meraGPT posts Decider 1 ahead of Jev on a teacher-labelled set

decider-4b v2
Mapika's open row at the top of the v1.4.2 harmonic mean, 64.13. v1.4.2.2 keeps that cell and ranks Imajev-4B and Plumb-4B above it. Intelligence is 49.4 against Jev at 53.1. The cost cell is an estimate from a Qwen3.5-4B list price, not a GPU bill.

JevBench v1.5 ranks Cygnet 73.7 and Jev 1.13.0 72.1

Decision 2.0
Six Apache-2.0 checkpoints from vLLM Semantic Router, posted October 3, 2026. The cards name Kai, Eos, Sol, Nox, Lux, and Vega. A call returns a probability for every listed option and does not write a reply.

Decision 2.0's Vega card prints 56.5 on its own Decision Index run

Decision 3.0 family
Six Apache-2.0 cards opened October 11, 2026. Their own 0.3.1 index cells are d3 64.7, d3-flash 59.0, d3-mini 54.2, d3-nano 37.2, d3-lite 29.0, and d3-edge 18.0.

Opened October 26, Decision Index 0.4.1 Full score for d3 is 67.15; d3-turbo and d3-ultra have their own pages

Decision API is not enabled
The HTTP 403 sentence from POST https://api.openai.com/v1/decisions on October 2, 2026, with this desk's key, and again from an empty body on October 4. everruns pull 3924 recorded the same sentence on September 30. On October 6 a call with model gpt-6-luna returned HTTP 200, and an empty object returned HTTP 400, missing model.

OpenAI Decisions API is generally available; this desk's October 23 POSTs returned HTTP 200

Decision head
The small stack trained to score a fixed set of options. Clef, Kev, Laya, and Unsloth each publish their own version of it.

Open decision models start from an open language model

Decision Index
A chance-corrected average of 40 public benchmarks in five equal areas. Zero is random guessing and 100 is perfect. Unanswered requests count as wrong. Edition 0.2 is dated September 24, 2026. The kit's test locks Jev at 51.67.

Decision Index 0.2 prints Jev at 51.67, and a later post names another first place

Decision LCR
Subquadratic's conversion of Artificial Analysis AA-LCR into 118 multiple-choice decisions over 72K-115K token document sets. The blog prints Snap 74.0 one-shot against Jev 48.0 chunked, and says the scores cannot be compared with published AA-LCR results.

SubQ Snap 1.1 prints 65 on Artificial Analysis Decision Index, $0.04 per million input

Decision Model Factory
Yuma Ichikawa's recipe pipeline for specialized decision models on Gemma 4 backbones. arXiv 2610.34956. Table 1 prints DF-JA-Large at 67.63 on S1MB Japanese Task Avg after specialization.

Decision Model Factory prints DF-JA-Large at 67.63 on S1MB Japanese Task Avg against a public snapshot high of 60.05

Decision rate
How often the sim asks Jev for a new path. The README caps this at 4 Hz in traffic and about 1.5 Hz on an empty road. Single-answer questions are resolved locally.

JevPilot is a playable driving sim that asks Jev which path to take

decision_weight
The multiplier on the summed Noul probabilities. Both published configs set it to 10.

On WANDS, more Jev questions move the mean to 0.610 and leave the median at 0.561

decision-v7
Author 10-source typed decision suite used in the MiniCPM5-2B-Jev README. The project prints 86.41% accuracy and ECE 0.0307 on that suite.

MiniCPM5-2B-Jev prints 78.79% on JevBench, first among open models at or under 2B

Decisions API
Venice's endpoint POST /api/v1/decisions, which accepts state and typed questions rather than a chat transcript. OpenRouter uses the same name for POST /api/alpha/decisions.

OpenRouter, Cloudflare, and Netlify start serving Jev Venice lists Jev on its API: same key, no copy of the state

degrees@f518286e
The scheme hash for this corpus. Five Score questions share one state. Each criterion has five levels, 0 through 4, worth 5 points on a 0 to 20 scale. Five criteria sum to the 0 to 100 score the tables print. Rewording a criterion changes the hash.

One Jev pass scores 1,072 translations for $0.3165

Development set
Together's 1,000-item main set and 300-item policy-transfer set. The card says the mixture informed training, so the 88% and 100% are not an untouched benchmark.

Together prices Tev1 input at $0.04, and Ollama serves Choice, Score, and Noul

DF-Long
The factory's long-context specialist on Gemma 4 26B-A4B, about 4B active parameters per token. Table 2 prints S1MB Japanese 63.57 and JQaRA nDCG@10 90.1.

DiffusionGemma as Jev
A one-step read of google/diffusiongemma-26B-A4B-it. The canvas is seeded with the answer template, and the label slots stay noisy. mmastrac/djev, Apache 2.0, is the example server in front of vLLM pull 57250.

DiffusionGemma as Jev reads one denoising step, and a hand chart sums to 198 of 201

diode
Jevsus's main test. A statement is offered as a forced true/false Choice, both option orders. The README also publishes a native yes/no probability, the same Choice with a decline option, and the forced pick under a perspective prefix. The four are not merged.

Jevsus ran a true/false diode on jev-1.13.0, and 45% of statements move with the wording

Direct logit readout
One forward pass over declared option tokens, with no sampled answer. SemIf's 3090 note: 1.023 s for 21 questions versus 5.332 s for a compact JSON array from the same weights.

SemIf, a 4B open rebuild that reads option logits, sits 0.7 behind Jev on JevBench

direct mode
A jev-gateway outcome. Jev is confident about the tool, and every argument is an enum, a boolean, or a constant, so the gateway writes the tool call and does not call the language model.

jev-gateway asks Jev which tool a coding agent should call

Direct question
One configured Noul, with true and false criteria, asked of each of the top 100 products. The blog labels this column jev_reranker. The repo calls it bag_of_decisions_direct.

On WANDS, more Jev questions move the mean to 0.610 and leave the median at 0.561

djev
Maisa's hosted decision API on DiffusionGemma, and the name Matt Mastracci used for DiffusionGemma-as-Jev. JevBench v1.2.8 lists the hosted row at 74.3.

djev reads DiffusionGemma as a decision API, and sits third on JevBench

djev-run
Daniel Lee's Cloud Run recipe, GitHub taeold/djev-run. It serves mmastrac/djev-spark on an NVIDIA RTX PRO 6000 and exposes POST /v1/systemone. The repository page lists no license.

A Cloud Run recipe serves DiffusionGemma-Jev at 35 to 60 ms

DocJev
Jerry Liu's Apache 2.0 library for classifying and splitting PDF, DOCX, and PPTX files. LiteParse reads pages locally; hosted Jev returns the category or the page-range boundaries.

DocJev classifies and splits real PDFs with Jev, 5.7x to 6.5x faster than Luna on the author's set

does_pass
The binary evaluator in jev-as-a-judge. Jev matched the human oracle on all 500 repeated decisions in this run.

LangChain ran Jev as a judge: 500 matching pass/fail labels, and a $0.34 bill against Claude's $28

Dr. GRPO
In this repository, the advantage is the rollout reward minus the mean reward of the other rollouts for the same question. The code does not divide by the group's spread.

Step-Jev scores 19.6% when the reward grades every search step

Drex DLM
The card and repository title for the weights Nace posted on October 6, 2026. The post calls the release Drex 1.1. The card does not print 1.1. Backbone NVIDIA Efficient-DLM-8B. POST /v1/systemone. Weights CC BY-NC 4.0. Nace code MIT.

Nace posts Drex 1.1, and the card titles the weights Drex DLM

drex-max
Nace's pinned hosted id for Drex Max. POST https://console.nace.ai/v1/systemone. Docs say drex-latest does not point at it, and a request that omits model is answered by drex-v2.0.

Dry run
Operating against live market data without private transaction keys, simulating order fills when trade prints cross the resting quote.

A buy-or-sell every Monad block, with a mock default model

dual encoder
One encoder reads the state and another reads the candidate action. Both are a frozen Qwen3-8B plus a 20M projection head. The answer is a softmax over dot products. Action embeddings can stay cached while the state changes.

CLM-8B caches the action list, and a fine-tuned head scores 31 of 38 DeepSWE holdouts

duckdb-jev
Prasanth J's Apache 2.0 native C++ DuckDB extension. SQL functions call TypeSafe's Jev over HTTP, with batching, streaming, and an optional connection cache.

A native DuckDB extension batches Jev over SQL rows at about 2,300 rows per second on a live run

E4c
The fresh sealed set from look-alike family C, 200 windows. The agreement gate settled 76 of them. Accept precision there is 0.579, and 21 of the 76 accepted windows were attacks.

hunch runs EmbeddingGemma2 as a CPU System One endpoint at 20 ms on text and 100 ms on images

evaluate
Vercel AI SDK's experimental method for Jev, passing state and questions to receive typed answers rather than text completions.

TypeSafe starts pulling people off the Jev waitlist

evidence unit
The slice asked about in one request: a function, a file outline, a pair of copies, or a test. Tree-sitter finds it on the machine. The upload is that slice, bounded by upload_allow and upload_deny.

JevGate turns one function at a time into a finding at 0.80

Expected Calibration Error
A score for how far stated probabilities sit from observed accuracy. Lower is better. Poly reports 0.081 for ModernBERT and 0.105 for Jev on this Banking77 run.

Charly Poly put Jev next to open encoders, not GPT-5.6, and it lost on calibration

Fail open
Every error path returns the original input as steer, so a classifier outage does not drop the utterance.

Sam Saffron tries Jev as a hidden control plane for GPT Live in term-llm

fail_open
LiteLLM's default when Jev is unavailable: send the original request to the generator without compaction.

LiteLLM adds day-0 Jev 1.14 images, box questions, and long context on both decision routes

fallbackReason
The form router's label for why Luna decided. null when Jev cleared 0.95. low-confidence, missing-confidence, or jev-error otherwise. A failed Luna call does not return a reason or a destination.

Vercel's form router keeps Jev's destination when confidence is at least 0.95

False admission
A negative case the model treats as acceptable. Lemkin reports 47 of 148 for Jev (32%) and 20 for Sonnet (13.5%) on this SaaStr Connect sample.

Jason Lemkin tried Jev on SaaStr Connect and stopped on a 32% false-admission rate

flat page search
One Choice whose options are the pages, each described by its own text. The README says the request has to fit in 32k tokens and a Choice stops at 255 options.

four scene types
Feature descriptions, negation, mention versus the intended target, and conversational padding. The post gives one English example of each. The item list is the reply's report image.

One post scores Jev at 100 and Laya's English checkpoint at 92, on 100 items

frozen template
The abstract's setup for jev-1.13.0. One prompt template per dataset, held fixed, zero-shot, on the full evaluation split. The open reference models see the same requests and are scored by exact next-token probabilities over the options.

A 37-dataset paper scores frozen jev-1.13.0 against two open models

fsdecide
ForkScape's 149M ModernBERT-base encoder, release fsdecide-base-v11e4s21. The comparison doc says it was trained on about 34,000 labelled decisions from five app questions, and that the 450 bench items were kept out of training. The local server speaks POST /v1/systemone.

fsdecide scores 91.3% on ForkScape review, and Jev scores 56.3%

Browser Use's open harness that turns a page into a numbered list of controls and asks a System One model which to click. HiddenLayer ran the checkout through that harness.

HiddenLayer prints Jev at 91% Confirm Price on a checkout ad, and this desk's jev-1.13.0 still chose place_order at 0.89

jev.batch_size
How many rows realZachi/pg-jev packs into one System One request. Version 0.2.0 defaults to 20. The README's ground-truth check was 100% at 1 to 20 rows and 92% to 98% at 40.

Zachi's pg-jev judges 2,000 Postgres rows in about 3.5 seconds

Jeva
Qi Li and Xinchao Wang's System One architecture and the Jeva-4B checkpoint, posted October 14, 2026. Apache-2.0, from Qwen3.5-4B. The paper prints 0 flips on 600 Choice items and BANKING77 at K=16 91.62 against Jev-1.13.0 at 82.50.

Jeva-4B prints 0 flips on 600 Choice permutations, and BANKING77 at K=16 is 91.62 against Jev 82.50

JevArena
The score printed on the Decision 2.0 cards for a frozen prompt set. The footnote says a missing or invalid answer counts as an error. The cards do not print how many prompts that set holds.

Decision 2.0's Vega card prints 56.5 on its own Decision Index run

JevBench public subset
The 231 public tasks in JevBench, out of 534. Original 72, easy 48, hard 111. The other 303 tasks are private or judge-only, so a score on this slice is not the full benchmark composite.

Open-Jev 27B v1.1 answers 197 of 231 public JevBench tasks

JevBench Score
Benchmark Heaven's composite for typed-decision systems: Intelligence, Calibration, Speed, and Cost at 25% each, combined with a geometric mean. v1.2.2 reports Jev 1.13.0 at 75.3.

JevBench v1.5 ranks Cygnet 73.7 and Jev 1.13.0 72.1

JevBench v1.4
The edition the post cites. On this desk the v1.4.2.2 harmonic mean has Jev at 63.29. The live page on October 1 is v1.5.4, and a search of that text found no Mercury Decide.

Inception calls Mercury Decide first on OpenRouter's JevBench v1.4, and prints no score

jevbench.app
Yusuke's playground of recorded Jev runs. It is not fstandhartinger/jevbench and not the Benchmark Heaven ranking.

jevbench.app replays recorded Jev answers on labeled examples, and one test is 20 of 21

jevctl
npm package for Nasrallah-AL/jev-cli. The command is jev. It wraps TypeSafe's Jev as verify, screen, classify, extract, find, rerank, match, route, ask, compact, and batch.

jevctl puts Jev on the command line, with a compaction hook that keeps lines verbatim

jevel
A folder with one JEVEL.md. Frontmatter names the model, the required state fields, and the questions. jevelry reads that file. The body is for people.

jevelry turns a Jev call into a folder, a verdict, and a log

JevEval
DeepEval's custom metric that sends bounded Noul, Score, and Choice questions to Jev in one request and returns a weighted mean in [0, 1]. Apache-2.0. This desk's invented-breeze case scored 0.254 on jev-1.13.0.

On DeepEval's Paris weather example, jev-1.13.0 scored 0.254 when the answer invented a breeze

Jevflake
Luke Kranz's dbt package (and Terraform module) that creates Snowflake SQL functions for Jev's noul, choice, and score questions. Default model jev-1.13.0.

Spring publishes a Java client that asks Jev before the chat model runs

jevmod
Omar Hernandez's MIT package, version 0.2.1. One Noul per moderation category. Adult text flags at 0.80.

jevmod scores sexual text at 0.984 AUROC, and ZeroNSFW keeps the pictures local

jevonian/auto
The virtual model that asks Jev once for the route and the thinking depth. A named phase, a real model id, or routing.mode set to off does not make that call.

Jevonian asks Jev which model should take the next coding turn

Jevons paradox
The economic observation that increases in resource efficiency can expand total demand. The product is named around this economic hypothesis.

Almeida's bet on Jevons paradox over chatbot price cuts TypeSafe leaves stealth and ships Jev, a model that refuses to chat

jevsearch
Kyle McLaren's MIT shadcn registry block for site search. A lexical pass answers first; Jev re-ranks the top candidates in one request.

jevsearch re-ranks keyword hits with Jev and scored 83% Hit@1 on the author's TypeSafe docs set

JGLUE test row
The README's shared-API table. LFM: JNLI 17%, JCommonsenseQA 69%. Sarashina Q4: 34% and 86%. ModernBERT-Ja 310M, trained on the JGLUE train split: 93% and 92%. The page says this is not a fair ranking of model ability.

jev_local's Sarashina row beats LFM on two JGLUE tests, and the README says that is not a ranking

Join order benchmark
JOB, a standard set of join-heavy queries over IMDB-style data, used here as the reported test. The thread does not list which query subset or Postgres version.

A hybrid Jev overlay sped up Postgres joins 12% on JOB, and made the planner slower

jsort
Khaled Eltokhy's MIT command, installed as jev-sort. It asks Jev which of two texts ranks higher on a plain-English comparative, fits a Bradley-Terry scale, and prints the file in that order with a standard error.

jsort ranks a file by asking Jev which of two texts is more of something

Judgment
One typed answer to one question about one document. 37 documents times 21 questions produced the 777 count.

Jevflake's recommended dbt table: one stored answer per key and question, resent only when the row, the questions, or jevflake_model change.

Jevflake puts Jev in Snowflake: noul, choice, and score as SQL functions

jym
The command from syumai/jevyoumean. It wraps a CLI, and on an unknown subcommand asks Jev which documented command the token resembles, then can run that correction.

jym asks Jev which real subcommand a mistyped one was aiming at

keep-threshold
jev compact's default 0.5. A tool call or its result is kept when Jev's probability is at least this. LiteLLM's similar guardrail defaults to 0.2.

jevctl puts Jev on the command line, with a compaction hook that keeps lines verbatim

kettei-fat
Sqwish Labs' hosted decision model, model id kettei-fat. POST https://api.sqwish.ai/v1/decide. Docs price input at $0.06 per million tokens, output free. Opened October 17, 2026, JevBench API board v1.7.46 ranks it first of 39 at composite 77.8.

limited preview
OpenAI Developers' wording on September 29. Access was limited to selected API customers for testing. The follow-up said a broad release was planned in the coming days. On October 6 the Developers post said public beta for all developers. The DevDay recap, opened that day, still used the September wording. On October 22 the Developers post said generally available.

OpenAI's Decisions API preview says results come back in 150 milliseconds

list_fallback
A field on the jev-router pipeline stage. The guide says the value models_ignored means the include list matched no pool model, so the router used the whole pool. excluded_models still applies.

Arena scores typesafe/jev-router at +3.6% and $0.155 a task

Listwise Choice
One Choice whose options are the candidate passages. Hindsight 0.10.1 uses that shape. The probabilities sum to 1 inside the call, so the top score is a rank in that pool.

CLERC top-1 moves from 5% to 18% when jev-1.12 reranks the shortlist

LiteParse
The default local parser in DocJev. It extracts complete page text on the machine. Decision timing in the published pilots excludes this step.

DocJev classifies and splits real PDFs with Jev, 5.7x to 6.5x faster than Luna on the author's set

Literal reading
Answering the words in the instruction rather than the intent behind them. The docs say to put boundary cases in the criteria, or split the judgment into two questions.

TypeSafe lists nine ways Jev 1.13 is still jagged, and asks for more

live shadow
The speed chart's footnote for the 4 times escalation bar. Thousands of production conversations, run in parallel with the current model. Offline escalation on the same chart is 1.9 times.

Hono's author routes HTTP by meaning, then warns you not to What Jev returns: System One in plain language

number type
A Span-02 question that returns a numeric value and a confidence, without listing candidate numbers. The card marks number, reasoning, and images as extensions of TypeSafe's System One API.

Span-02's card prints Decision Index 0.3 text index 63.62, and the blog prints thinking off at 61.2 against Jev 58.0

O at 0.5
A Jev probability of at least 0.5 is marked O. 342 items sit on 0.5 (49, 291, and 2 by section). Marking those as X moves the gaps from 38.3, 11.3, and 36.8 points to 36.7, 11.5, and 37.5.

Jev keeps the same direction on 28,074 classical-Korean sentences

one box per question
TypeSafe Box docs, reopened October 16, 2026. Every Box answer is a single rectangle. TypeLLM's 05:44 UTC post says Jev 1.14 cannot return an array of vehicle boxes. This desk's type array POST, Date header 08:19:46 GMT, returned HTTP 400, Invalid request.

TypeLLM said Jev 1.14 cannot return every vehicle box, including Tesla's flying Roadster; this desk's every-vehicle Box was one rectangle, n = 3, and type array returned HTTP 400

one run
JEV.md says experiment 12 put this evaluator's run-to-run range at 1.12 points, and that a single run reproduced the median of three at Pearson 0.998. The corpus therefore scores each language once. The same note says 12 of 268 port-check rows came back bit-identical, so the evaluator is not deterministic.

One Jev pass scores 1,072 translations for $0.3165

one sentence per call
The Jev run puts a single Korean translation in the state. The three chat models scored twenty sentences in one prompt. The note treats that as the remaining difference in conditions.

Jev keeps the same direction on 28,074 classical-Korean sentences

one shared screenshot
The cost table in awlevin's README. One decision, same screenshot and goal. Jev is $0.0002 and 0.13 to 0.38 seconds. Claude Opus 5 on the bare image is $0.032 and 5.2 seconds. The page says Opus read the dates from the pixels and this loop annotates them in code.

JevPilot is a playable driving sim that asks Jev which path to take

plpython3u
The untrusted Python language PostgreSQL needs for this extension. The README says the function performs external HTTPS work inside the statement, and that a rollback does not undo a request already sent.

pg-jev puts prompt_jev() in PostgreSQL and returns jsonb

pointer head
The small scoring head that replaces the language-model head. The blog says it is just over a million parameters and compares each option's hidden state with the hidden state at an answer position. The earlier slot head is described as worse.

JevBench v1.5 ranks Cygnet 73.7 and Jev 1.13.0 72.1

second reading
When the first pass is unsure, rev scores the options again in reverse and averages them. Confidence stays at the lower of the two readings, so a 0.9 gate still reflects one reading.

rev reads a frozen Qwen and posts 0.784 on public hard items

Seeded canvas
The fixed text of the answer is written into the diffusion canvas before the forward pass. One denoise step then returns a distribution at each noisy slot.

Set B
Per-company questions on standing and journalist shape, then a tier. A story can land on several of the 15 illustrative desks, or none.

Jev scored 384 morning headlines in 25 seconds; Opus 5 finished four

settle
After each action, dejevu waits until the DOM is quiet and the requests that action started have finished, with a cap per action type. The README contrasts that with fixed waits, and says jev-ultrafast discards 4 to 6 of 17 calls because the page changed under them.

dejevu books the same Flights search faster than the published Jev demo, on another machine

Shadow mode
Classify and log the label, then act as if control_plane is off. The PR default for live.classify.shadow is true.

Sthānika's Sieve-31B card prints Decision Index 0.3.2 Full score 63.8

signup pause
TypeSafe's September 22 statement that new Jev accounts were temporarily not being created, while accounts that already signed up kept working. On September 27 at 22:30 UTC the same account posted that signups were open again, and that new signups no longer get free credits. On October 6, 2026, at 17:05 UTC, a new console account on this desk showed available credits of $0.00, with no payment method and no billing history. On October 8, 2026 the same signed-in console still showed available credits of $0.00, no payment method, and no billing history. Usage for the last 7 days was $0.00, 0 tokens, and 0 requests.

Opened October 17, JevBench API board v1.7.46 ranks kettei-fat first of 39 at composite 77.8

sink, don't sort
postgres-search keeps a top-10 hit in place when its Noul is at least 0.30, and moves a lower score to the bottom of those 10 without reordering either group. The docs say a correct product scores near 1 for close variants too, so sorting by the probability would shuffle good rows.

postgres-search can sink a bad hit, and the README has not measured that step

Sistema 1
Coronado's name for the typed path. Six closed questions in one POST /v1/systemone, probabilities only, no generated text. On the realtime table, N=5, mean progress is 24.9% at 408 ms a decision.

Step Jev
A Qwen3.5-4B-Base LoRA that scores one observed search step. The score used in training is P(positive) minus P(negative).

Step-Jev scores 19.6% when the reward grades every search step

StreamDecisionBench
Jacob Lin's October 2, 2026 chart of the decision in force while the state keeps changing. The single-model score is normalized log-AUC from 0.5 to 8 seconds. The site HTML we opened did not render the table. The code link in the thread points at the same site.

StreamDecisionBench puts Kev-27B at 62.15 and Jev at 59.63

strict_mode
JevEval setting that returns 1 only when every applicable question is answered in its best way from Jev's probabilities, and 0 otherwise. Invented-breeze 0. Clean 1.

On DeepEval's Paris weather example, jev-1.13.0 scored 0.254 when the answer invented a breeze

Stripe shortlist
Eight passages this desk wrote about Stripe keys or webhooks, including Roll secret, the signing-secret page, HMAC verification, and a trap that rotates the API secret key instead.

On eight Stripe passages, a 0-9 Score put Roll secret at 8.86 and the other six at 2.42 or below

Stripe ticket
The October 6 desk sentence Hi, I've been trying to connect my Stripe account for 3 days and the integration keeps failing. I'm losing sales. Please help ASAP. On October 13, 2026, at about 03:00 UTC, Snap returned urgency noul 0.98, 119 input tokens, 0 output, desk clock 1,195 ms, then chose technical at confidence 0.90, score 0.98, noul 0.98, 235 input tokens, desk clock 2,291 ms.

SubQ Snap 1.1 prints 65 on Artificial Analysis Decision Index, $0.04 per million input

Structural invariant
A relationship you might expect between two questions, such as P(yes) on a Choice matching a Noul, or a Noul and its negation summing to 1. The docs say jev-1.13 does not guarantee those identities.

TypeSafe lists nine ways Jev 1.13 is still jagged, and asks for more

Structured read
OpenJev's path, as LocalJev describes it: a one-step DiffusionGemma pass that needs seeded canvases, read-only denoising, and selected-token logprobs, which stock oMLX does not expose.

djev reads DiffusionGemma as a decision API, and sits third on JevBench GitHub Next ships LocalJev, a prompted stand-in that speaks /v1/systemone

student graduation
In Mastracci's October 27 thread, the local student trains on EmbeddingGemma2 embedding vectors until it is confident it matches the teacher, then checks in only occasionally.

hunch runs EmbeddingGemma2 as a CPU System One endpoint at 20 ms on text and 100 ms on images

SubQ Snap
Subquadratic's hosted decision model. Docs opened October 23 name subq-snap-1.1 at $0.04 per million input tokens, output free. GET /v1/models listed subq-snap-1.1 and subq-snap-preview. Date headers 02:23:17 GMT to 02:23:20 GMT October 23, three POSTs from this desk returned HTTP 200. The October 12 blog prints Decision Index 0.2.1 at 61.7 against a Jev cell of 57.9.

SubQ Snap 1.1 prints 65 on Artificial Analysis Decision Index, $0.04 per million input

subq-snap-1.1
Pinned Decision model id on the Models page opened October 23. Whedon wrote that the preview slug routes to it. A POST with that id on October 23 named subq-snap-1.1 in the response. Artificial Analysis Decision Index prints 65, tied with d1-ultra and Elephant 9B.

SubQ Snap 1.1 prints 65 on Artificial Analysis Decision Index, $0.04 per million input

swift-jev
Daiki Matsudate's MIT Swift package and CLI. Choice answers are enum cases. Noul answers are probabilities. Score answers can fall between rubric levels. One evaluate call sends every question.

swift-jev types Choice, Noul, and Score, and routes at 0.60 and 0.85

System One
TypeSafe's term for a model returning structured decisions with probabilities rather than text output, inspired by Daniel Kahneman's distinction between fast and slow cognition.

TypeSafe leaves stealth and ships Jev, a model that refuses to chat

Target element
The specific page element receiving the selected action. The repository states that both heads share a request to avoid mismatched actions and targets.

Browser Use wires Jev into the click loop: 7 seconds, $0.0039

Task 1
Given-aspect valence and arousal on a 1 to 9 scale. Ten corpora, six languages. The headline is micro RMSE over every annotation. Lower is better. The paper's number is 1.0645.

A frozen Jev pipeline reports the lowest ten-corpus valence-arousal error in a SemEval table

teacher average
The blog's name for the reference on typed-decisions: the mean of three samples from teacher models. It says two single samples agree 73.5% of the time, so a model can match the average more often than one teacher matches another.

meraGPT posts Decider 1 ahead of Jev on a teacher-labelled set

ten-call clock
October 7, 2026 desk clocks on the Stripe sentence, ten measured calls per host after one warmup. Urgency alone: Jev median 330 ms, Decisions median 267 ms, openai-processing-ms median 64 ms. Three quickstart questions: Jev median 338 ms, Decisions median 269 ms, processing header median 68 ms.

OpenAI Decisions API is generally available; this desk's October 23 POSTs returned HTTP 200

Tev1
Together AI's experimental Qwen3.5 decision model, in 4B and 0.8B sizes. The Together chat call returns one letter. Ollama's library page serves it as Choice, Score, or Noul.

Together prices Tev1 input at $0.04, and Ollama serves Choice, Score, and Noul

three-set mean
The fourth column. It is the average of the three printed percentages. Jev 80.8%, Bonsai 2 67.2%, Luna 85.4%.

A Japanese table has Jev at 96.0% on one set and 56.0% on JamC-QA

Threshold
The minimum score required for a match (defaulting to 0.5). The first description whose Noul probability exceeds this value triggers its handler.

Hono's author routes HTTP by meaning, then warns you not to

THX-01
HAL-X's 322M decision model, Apache 2.0, on mmBERT-base. The card's support-ticket average is 98.4 against Jev 1.13 at 97.4 on 2,843 tickets.

THX-01 averages 98.4 on its 2,843 support tickets

THX-01 API
The docs page names POST https://api.hal-x.ai/v1/systemone and model thx-01. The October 11 post calls the API free. The docs page we opened does not print a price.

THX-01 averages 98.4 on its 2,843 support tickets

THX-01 number and excerpt
The card's question types add number, excerpt, and cite beside choice, noul, and score. Number lookup on the card is 93.4. Jev 1.13 on that line is 96.6.

THX-01 averages 98.4 on its 2,843 support tickets

tier 0
Hard denies in the offline eval that do not need a model. 12 of 22 catastrophic commands in the 80-entry corpus were caught there. The other 10 were caught by the degraded ask path.

Jevrail scores a shell command before it runs, and the printed corpus leaves the model off

ToddlerJev
Teenage Works' open-weight audio decision model, Hugging Face TeenageWorks/Toddler-Jev, Qwen Research License. Posted October 18, 2026. MMAU-mini 68.70%. Base Qwen2.5-Omni-3B with a rank-16 LoRA and a pointer head.

ToddlerJev prints 68.70% on MMAU-mini, with weights under the Qwen Research License

TokenBreak
HiddenLayer's 2025 attack that edits how words split into tokens. The October 14 Jev write-up used a denser, targeted form on 30 toxic prompts. At baseline both Jev and the analog flagged all 30.

HiddenLayer prints Jev at 91% Confirm Price on a checkout ad, and this desk's jev-1.13.0 still chose place_order at 0.89

top 128
After the local word match, JEV reads at most 128 candidates and moves the ones that fit the query. Files it does not check stay in the list as local matches. A search with no API key never makes that call.

JEV Search moves NFCorpus nDCG@10 from 0.322 to 0.377

tree search
PageIndex builds a hierarchy of titles and summaries. Jev picks a child at each level. The script keeps a beam of 3, then runs one Noul per candidate page, up to 16.

PageIndex walks long filings with Jev Choice calls and checks two answers

TrueForge
TrueFoundry's MIT-licensed agent harness. npm @truefoundry/trueforge 0.178.0, opened October 14, 2026, requires Node 22.14 or newer. Local mode is one process on SQLite.

On 40 client requests, Jev and Opus both scored 37 of 40, at $0.0015 against $0.005 to $0.015

Two-week paid-team reach
The October 2026 Production Index launch table's 35.3% of paid teams in Jev's first 14 days, gateway launch Sep 17. TechCrunch rounds that cell to 35%. 0.27% of spend in the summary, 0.3% on the scorecard, and 0.15% of September spend are three prints.

Vercel's October 2026 AI Gateway Production Index prints Jev at 35.3% of paid teams in its first two weeks

TypeSafe-Danger-Zone-
Prefix LiteLLM forwards to TypeSafe deployments only, opened October 15, 2026. TypeSafe-Danger-Zone-Images: true turns on images and box. TypeSafe-Danger-Zone-Long-Context: true raises both caps to 262k.

LiteLLM adds day-0 Jev 1.14 images, box questions, and long context on both decision routes

TypeSafe-Danger-Zone-Images
HTTP header, value true, required on every TypeSafe request that contains an image or a Box question. On October 15, 2026, Date header 01:22:14 GMT, a request with an image and no header returned HTTP 400.

A green Continue button scored noul 0.99 on jev-1.14.0, n = 3, and an empty field scored 0.02

TypeSafe-Danger-Zone-Long-Context
HTTP header, value true. Opened October 15, 2026, the models page sets both the per-request context and the per-question context to 262k tokens when this header is present. It works on Jev 1.14 and Jev 1.13.

TypeSafe-Danger-Zone-Long-Context raises both Jev context caps to 262k tokens

typesafe/jev-1.13
The OpenRouter model string main.py passes when use_jev is true. The script does not print a served version such as jev-1.13.0. The checked-in default is use_jev = False. results.json contains one true run and one false run.

A 100,000-line needle takes 18.0 minutes with Jev and 24.7 without

typesafe/jev-1.14
OpenRouter model id for Jev 1.14. Opened October 15, 2026, the page lists $0.042 per million input tokens, output free, and a 262K context. GET /api/v1/models did not list this id. This desk did not call OpenRouter.

On October 26 TypeSafe's jev-latest named jev-1.14.0, and both aliases point at 1.14.0

typesafe/jev-router
OpenRouter's chat model id for Jev Router. The guide says Jev scores the conversation and the router picks a model and a reasoning effort. The response is text from the model that served the request.

Arena scores typesafe/jev-router at +3.6% and $0.155 a task

TypeSafeClassifier
A LangChain Runnable that submits state alongside defined Choice, Score, or Noul queries to Jev, returning structured results rather than text generation.

LangChain ships a Jev classifier, then parks it on the agent loop

v1.5.4
The JevBench page we opened September 30. It numbers 106 systems. Cygnet stays 73.7, Winnow-12B Q8 stays 73.2, and Jev 1.13.0 stays 72.1. Former addenda now have official ranks and keep the addendum tag. The capability control says 60 Jev-class systems.

JevBench v1.5 ranks Cygnet 73.7 and Jev 1.13.0 72.1

v19
The reference Strands Decider recipe in the repository. At the 3072-token window it was preregistered at, the file prints 167 of 231. Served at 4096 tokens the same note prints 168. v20 scored 169 at 4096 and did not replace it.

Strands Decider 2B scores 167 of 231 public JevBench tasks

Vega, Decision 2.0
A different checkpoint, Decision-2.0-Vega-27B from vLLM Semantic Router. Its card prints Decision Index 0.2.1 at 56.5. The write-up is the Decision 2.0 page.

Vega, the vegaml package, scores 75.4% on 800 phishing emails against Jev at 61.9%

vegaml
NandhaKishorM/vegaml, Apache 2.0. Default checkpoint 0.8B on frozen Qwen3.5-0.8B, plus a 4B. The README's phishing row is 75.4% against Jev 1.13.0 at 61.9% on 800 emails.

Vega, the vegaml package, scores 75.4% on 800 phishing emails against Jev at 61.9%

Vela 2.0
Four Apache-2.0 checkpoints from KR Labs and vLLM Semantic Router, posted October 7, 2026. A call can return Choice, Noul, Score, Span, or Set. The model does not write a reply.

Vela 2.0's 9B card prints 41.63 on Decision Index 0.2.1

Verbatim keep
Retaining original tool outputs unchanged in context without summarization, preventing drift in variable names or error logs.

Compaction without summarization: score the tool calls and drop them

verdict
act, mark, or fall_back, chosen from thresholds in the jevel. act means the probability clears the bar to use the answer. mark means use it and flag it. fall_back means do what the code did before the call.

jevelry turns a Jev call into a folder, a verdict, and a log

verified run
In dejevu, a run counts only when code checks the final page. The README says the model announcing that it is done is not the check. Flights must show results. Wikipedia must land on the exact article URL.

dejevu books the same Flights search faster than the published Jev demo, on another machine

visual inputs
Tibo Sottiaux's phrase on September 29. The OpenAI Developers follow-up says to send text or images as context. The October 6 guide says images must be inline base64 data URLs. The GPT-6 Luna model page lists image as an input modality and marks image generation as not supported. This desk did not send an image.

OpenAI Decisions API is generally available; this desk's October 23 POSTs returned HTTP 200

VoxCeleb1-O EER
Equal error rate on a speaker-verification split. Qwen-Audio-Jev prints 6.50% for its Noul setup.

Qwen-Audio-Jev prints 78.70% on MMAU-mini and about 20x the base model's speed

Waitlist
TypeSafe's early-access queue from launch through September 20, 2026, when the company posted that Jev was open with no waitlist.

TypeSafe drops the Jev waitlist; new accounts start with $5 TypeSafe starts pulling people off the Jev waitlist

WaterSheep
Samrat Dutta's Apache-2.0 fine-tune of ModernBERT-base. The README serves POST /v1/systemone on port 8766 and adds a multi-label question type.

WaterSheep fine-tunes ModernBERT and serves /v1/systemone with a multi-label question

web context
In the Exa demo, search snippets placed into the state Jev judges. The page says Jev is asked the same yes/no question with that state and without it. No scored pair was printed on the page we loaded.

Exa posts a demo that puts web results into Jev's state

weekly-client-follow-up
Akshay Pachaar's TrueForge agent that shortlists 10 GitHub issues per client request and asks Jev which issue matches, or none. Accept at 80% confidence, 90% if the issue is closed.

On 40 client requests, Jev and Opus both scored 37 of 40, at $0.0015 against $0.005 to $0.015

Werdykt
basal's hidden benchmark, v1, exported October 4, 2026. 5,000 decisions, 10 categories in Polish and in English, 250 questions a cell. The questions are not published.

basal-1.5 scores 72.12% on Werdykt, and Jev 1.13.0 scores 81.64%

Werdykt v1
basal's hidden 5,000-decision set, 10 categories in Polish and in English. The ultra card prints 0.879. The questions are not published.

Opened October 19, JevBench ranks basal-omni-1.0-ultra first of 184 open systems on Capability at 82.5

Whole-document read
A question whose answer needs the page as a unit, not a short snippet. Kumar's 135-row extraction gate is the example: Jev matched later outcomes 68.6% and the probability swung by 0.5 between runs on the same page.

Aman Kumar ran about 16,000 Jev calls and called it a filter, not a classifier

Workers AI
Cloudflare's serverless inference runtime, executing queries via env.AI.run('typesafe/jev', { state, questions }).

OpenRouter, Cloudflare, and Netlify start serving Jev

WrangleBench
John Crown's chart of perfect matches per 200. The printed bars are 137.3 with Jev and 105.1 without. The post says the full benchmark is still to come.

Wrangle's chart prints 137.3 perfect matches per 200 with Jev

x_celeris.explain
Optional Celeris field that returns one sentence per question. Docs say explanations make the request slower. Output tokens, including those sentences, are free.

Celeris-1 Decision prints 80.0% on 3,210 jev-bench items at a 67 ms median, and Artificial Analysis lists it at 52

x402 wallet
A prepaid USDC path Venice lists next to a Bearer API key for authenticating decision calls.

Venice lists Jev on its API: same key, no copy of the state

Zero-probability miss
The model assigns probability 0 to the correct label. Poly reports this on 6.6% of Jev's decisions and on none of 1,155 decisions from each of the three open encoders. A zero cannot be recovered with a threshold.

Charly Poly put Jev next to open encoders, not GPT-5.6, and it lost on calibration

ZeroNSFWBot
SeYeD.Dev's Telegram bot. Pictures are scored on the host. Jev reads clipped profile and message text when a key is set.

jevmod scores sexual text at 0.984 AUROC, and ZeroNSFW keeps the pictures local
