Hosting = where inference runs; company = where the provider or lab is registered.
EU hosting means the route's inference runs inside the EU: an EU region, AWS Bedrock's EU cross-region (geo) profiles, Azure's Europe Data Zone, or a provider whose entire public fleet is documented as EU-hosted, each checked per model against the provider's documentation. Global deployments do not count, and neither does an EU billing region, an EU company or an EU control plane on its own. One disclosed company-policy exception stays in, marked “EU equivalent”.
Evidence requirements (benchmark evidence, priced provider, measured task tokens) sit above the table they apply to.
“Hide deprecated” removes retired models (every Artificial Analysis configuration retired, on no current DesignArena board) and older retired configurations of current models. Applies to model tables, charts, price views & model offers; benchmark evidence stays unfiltered.

Capability ranking of Jev-class systems
Capability Score averages Intelligence and Calibration. Imajev-4B leads the Jev-class systems with 66.3.
Jev-class means at most 2× the cost and median latency of Jev. How we choose ↘
Wide coloured bar = Capability Score (0–100). Thin bars: cost above, median latency below; shared log ratio scale 0.25× … 64× Jev, ticks at 1× and 2× (cap). Shorter is cheaper or faster. * = est. (estimated cost). # counts ranked Jev-class systems; “–” marks unranked or outside systems. Tap ⓘ or hover a row or thin bar for details.
Cost and latency are shown separately because they are nearly independent across systems (Spearman ρ = 0.17, n = 91).
Sorted by Capability Score, not numbered. Each row says which limit it misses, measured against Jev 1.13.0 ($0.040 per 1,000 decisions, median 0.65 s).
Jev-class = cost per decision at most 2× Jev 1.13.0's (≤ $0.080 per 1,000 decisions) and median latency at most 2× Jev 1.13.0's (≤ 1.30 s), the adjusted p50 — the same median the speed chart plots, not the four-axis Speed score. 52 of 93 systems qualify; the other 41, including the general-purpose LLMs, are listed below the divider in the ranking. JevK5 v0.2.0, OpenSourceJev have no recorded median latency; for them the Speed axis decides, at the 2× latency equivalent (Speed ≥ 77.2). The charts below show speed and cost beside Capability Score; the official JevBench Score weighs all four axes.
Jev-class systems are shown by default. Bubble size follows the official JevBench Score; official rank stays unchanged. The five most capable Jev-class systems are labelled.
Upper right is best: more capable and cheaper. Cost is USD per 1,000 decisions on a log scale. The dashed line is 2× Jev’s cost.
Upper right is best: more capable and faster. Speed here is the median-latency speed — the same adjusted median (p50) latency the Jev-class limit uses — a log scale, so each 20 points is 10× faster (median under the numbers). Self-hosted systems are plotted at the est. incl. network latency (2x measured + 150 ms); their measured loopback p50 (on-GPU, no network; not directly comparable with API latency) is in the tooltip. The dashed line is 2× Jev’s median latency.

Base-model notes
Weights are relative: each axis counts in proportion to its slider. The score stays a weighted harmonic mean with the low-axis gates; an axis at 0 drops out together with its gate. Only equal weights give the official JevBench Score and rank.
Score = 4 / (1/I + 1/C + 1/S + 1/K) (each 0–100; × (axis / 50)² for Intelligence, Speed or Cost below 50)
Pick any two. Four radars: the score axes, accuracy per tier including the sealed set, accuracy by family on the current v1.4 question set (hard tier and sealed set together), and the sealed set alone. Further out is better on every spoke; the link keeps the pair.
Imajev-4B has no published hard-tier family breakdown; families that need it are left out (—).

Greener = stronger within its column; faster counts as stronger. Badges: API sealed text went to the operator's endpoint · est. estimated price · ann. announced price not yet bookable · not ranked partial run or honorable mention · new first listed in v1.4.2.2.
* Self-hosted rows: the first value is the p50 we measured on our own hardware over loopback (on-GPU, or on-CPU where marked, no network). It is not directly comparable with API latency, which we time end to end from our measuring host, network included. “est.” is the est. incl. network (2x + 150 ms) that the ranking and the latency cap use for every self-hosted row. Model authors can ask us to time a hosted endpoint instead (on request).

One forward pass per decision: softmax over the declared options' answer-letter logits at the last position divided by the package's own T = 2.07 (jevk5_config.json), up to 16 options, 0 generated tokens; inputs over 16,384 tokens are refused rather than truncated. Disclosed by the author: no JevBench item was trained or tuned on and every checkpoint and temperature choice came from his own held-out sets, but the 231 public items were scored after each of five training rounds and that aggregate feedback shaped the recipe (hard mining, long documents, document length) — development against the public distribution, stated plainly. His own overlap audit dropped 9 training items sharing more than two 8-word spans with a public item. Independent top-five gate (25 Sep 2026): LEGIT — cost basis (same as its JevK5 parent), public-versus-sealed gap against like-for-like rows, an 8-gram screen of its released training data (no row shares more than two 8-grams with a public item) and an exact composite recomputation.

| 67 | JevAct †Requested in GitHub issue #66. The author published an endpoint and an evaluation client, not weights, and his API is not the TypeSafe wire format, so JevBench's own `jevact_api` adapter implements exactly the mapping table in his eval_code.zip: state to state, instructions to the question, the labels with their criteria text as the options in label order, noul as false/true, and results[0].options[i].probability read back as the probability of labels[i] by index. His server answers HTTP 400 with `all inference items exceeded max_context_tokens or contained reserved markers` for an input it cannot take, and his own client and test script record exactly that as one failed item and continue; the adapter therefore surfaces that one documented refusal as the harness's 422 refusal path, which scores it as a wrong answer and does not count toward the stop rule - the same treatment the swanOne and Cygnet packages get for their own 422. Any other 400 or an outage still stops the run. The endpoint reports no token accounting, so cost is the labelled 2B size-class estimate. The endpoint is one machine in China and the latency includes that distance; it is not a production API and gets the standard x2 self-host adjustment, without the +0.15 s that only our own servers carry. 237/308 sealed items answered validly (failures count as wrong) | 16.9 | 29.3 | 55.1 | 76.5 | 64.3 | 61.9% | 23.4% | +38.5 pp | est.$0.015 | 0.40 s | author demo |
| 68 | djev †Experimental full-generation path over the same DiffusionGemma checkpoint as djev-dev: thinking was enabled and the model could generate up to 8,192 tokens before returning its distribution. Current djev-dev itself hard-codes enable_thinking=false, diffusion_max_steps=1 and read_only=true, so this is not a switch in its published typed API. It is substantially slower/costlier, and 72/534 requests exhausted the output budget without a parseable distribution; those are failures. Cost uses measured tokens and a same-size hosted reference, not the H200 rental bill. 220/308 sealed items answered validly (failures count as wrong) | 15.2 | 71.6 | 87.8 | 75.2 | 26.9 | 87.4% | 60.1% | +27.4 pp | est.$0.274 | 0.426 son-GPU, no networkest. 1.00 s* | RunPod GPU |

| 76 | Instinct †Requested in GitHub issue #69. A free evaluation/demo endpoint that speaks TypeSafe's /v1/systemone wire format, so the unchanged typesafe adapter ran it and no mapping of ours was involved; we registered the account and created the key ourselves in their console. The author states frozen Qwen3.8-27B base weights with no fine-tuning, read in one forward pass per question with no autoregressive decoding; the serving stack is not public, so nothing about it could be reviewed and the row rests on the API's own behaviour. Cost is an ESTIMATE: ZooWork publishes no bookable price, so the base model's public reference price is used (OpenRouter model-level qwen/qwen3.8-27b, $0.42/M input, zero output for a direct-logit readout); the author-announced tariff is not used. Classified as a free evaluation/demo endpoint (no SLA, no status page, no terms, pricing 'to be announced'), so the x2 latency adjustment applies.

| 84 | verdict-small †Requested in GitHub issue #73. Run through the author's own `verdict serve` on our CPU, which speaks TypeSafe's /v1/systemone wire format, so JevBench's unchanged typesafe adapter ran it and no mapping of ours was involved. A 118M multilingual bi-encoder: every option is scored against the rendered state by cosine similarity, at the model's own scale (temperature 1.0, no calibrator fitted on JevBench items, as the author states). Structured state is rendered as `key: value` lines by his own code. Code review before the run: the only network call is the Hugging Face download of his own checkpoint, no telemetry, no key, no rule written against public items. The `usage.input_tokens` his server reports is a word count and not a tokeniser count, so the cost is the labelled size-class estimate rather than a measured token price. Self-host latency gets the standard x2 + 0.15 s adjustment. The author's own public-set figures were easy 0.938, standard 0.486, hard 0.396 on an Apple M5 CPU.

I = 0.8 × I_v1.3 + 0.2 × I_sealed, where I_sealed = 100 × max(0, (acc_sealed − 0.293) / (1 − 0.293)). Public and sealed scores are published only as aggregates.C = C_v1.3 + (C_v1.4 − C_v1.3) × min(1, 0.2 / 0.35).k = 1 generalization penalty reduces Intelligence when public accuracy exceeds sealed accuracy by more than 25 percentage points: I × (1 − max(0, gap − 25) / 100). It rewards systems that generalize beyond the public half.p = −1). Intelligence below 50 keeps its quadratic penalty; Speed and Cost each have a separate Jev-class gate below 50. Speed and Cost axis calculations are unchanged from v1.3.0.The chart and table above compare the tested systems, not marketing claims. These are the practical answers readers most often need before choosing a Jev-class decision model.
The highest-ranked open entrants in this run are Imajev-4B (#1, 67.4), Plumb-4B (#2, 65.8), Hopper (#7, 59.4), Winnow-12B Q8 (#8, 55.6). “Open” here means the tested row publishes code or weights; check the licence and exact configuration in the board before adopting one.
Open entrants with released code or weights can run on infrastructure you choose, including EU infrastructure. That can support data residency, but neither open source nor an EU server makes a deployment GDPR-compliant by itself. Assess your data, contracts, retention, subprocessors and security for the complete setup. See Benchmark Heaven's broader EU-hosting comparison.
jev-router.com offers self-hosted open decision models. Neutrality disclosure: it is run by the authors of this benchmark; it receives no scoring advantage and is not a ranked entrant.
The official score is the equal-weight harmonic mean of Intelligence, Calibration, Speed and Cost. Version v1.4.2.2 measures 534 public and 308 sealed decisions: 20% of Intelligence comes from the sealed set, a public-minus-sealed gap above 25 points costs Intelligence, and Intelligence, Speed or Cost below 50 each pull the score down quadratically. What changed in v1.4 · method and tiers.

New entrants use the same frozen harness and appear in a new version. For private data, see the custom evaluation options.
Every price here is US dollars per 1,000 decisions — not per 1,000 tokens. One decision is a whole question — state, rubric and options — about 950 input tokens for Jev 1.13.0, so at its $0.042 per million input tokens 1,000 decisions cost $0.0399.
One decision is a whole question, not a token. Jev 1.13.0 reads 950 input tokens per decision on average over the 534 v1.2 decisions. At its public tariff of $0.042 per MILLION input tokens (output tokens are free, https://docs.typesafe.ai/models), 1,000 decisions therefore cost 950 x 1,000 x $0.042 / 1,000,000 = $0.0399. That is what the Cost column shows: $0.0399 per 1,000 decisions, not per 1,000 tokens.
Systems with a public tariff (per token or per request) are priced at that tariff times the tokens we measured. Systems without one — open weights, author demos, models we ran locally — are priced as if a large inference provider hosted them: the OpenRouter list price of the same weights; if OpenRouter does not list them, the nearest larger sibling; if no model of that size class is on OpenRouter, the DeepInfra list price of the same weights or of the nearest larger model of the same class. We do not use per-minute GPU rental or our own CPU time — providers buy capacity in bulk or own the hardware, and price accordingly. Price × tokens per decision = $ per 1,000 decisions, marked “est.”.
Price rules from v1.4.3 and v1.5 on (disclosed before any v1.5 result): only public, bookable list prices that have been in effect for at least 30 days count; promotions, subsidies, credits and free tiers do not. The scoring price is never below the market reference price of the system's base model, found the same way as the estimates above. A later price change triggers a re-score with a visible note on the row.

A metered row uses the provider's own tariff and its own measured token counts, including the requests whose answer could not be parsed; an estimated row uses the reference tariff for its weights or size class and, when the run reports no usage, the input tokens of the gemini-3.1-flash-lite run on the same prompts over the same 314 decisions. usd_per_1000 = (v11 x 314 + hard x 220) / 534.

Capability and Jev-class (headline ranking). Capability = (Intelligence + Calibration) / 2. A system is Jev-class if its cost per decision is at most 2× Jev 1.13.0's and its median latency (the adjusted p50 — the median the speed chart plots, not the Speed-axis score) is at most 2× Jev 1.13.0's; rows without a recorded median latency use the Speed axis at the 2× equivalent (77.2). The headline ranks Jev-class systems by Capability; the others, including general-purpose LLMs, are listed below a divider. This is a way of presenting the same measurements; it changes no score and no official rank.
JevBench Score. Equal-weight harmonic mean of Intelligence, Calibration, Speed and Cost (power mean p=-1). If Intelligence <50 multiply by (I/50)^2. For Speed and Cost separately, if below 50 multiply by (axis/50)^2. The weight sliders re-score the same axes with other weights for exploration; only equal weights give the official score and rank.
Intelligence. 0.8 × v1.3 chance-corrected Intelligence on the frozen v1.2 items + 0.2 × 100 × max(0, (sealed accuracy − 0.293)/(1 − 0.293)); then multiply by 1 − max(0, public-minus-sealed accuracy gap in percentage points − 25)/100. Original tier weights: easy .14, standard .28, judge .28, hard .30.
Revision v1.4.2.2. v1.4.2.2 adds the verified Imajev-4B row to v1.4.2.1 using the exact live v1.4.2 scoring code. Earlier measurements and score fields are unchanged; only ranks and preset ranks move where the new row changes the ordering. A 28 Sep text-only amendment clarifies that full-forward input tokens are counted once for the single pinned server pass; no measurement, score, axis, rank, eligibility, or numeric value changed.
Every system sees the same state, instructions, rubric and exact label set; only the transport differs. Requests go out one at a time with no retries, so latency includes the network. Estimated costs are hosted-provider prices for the same weights or size class and are marked “est.” — hover one for its basis, or see how costs are estimated. Every system has a price; none gets a free 100.
A service running another entrant's model is listed, but not ranked against the models. Ranking it would rank the same model twice, once at the model's own price and once at the service's. The row keeps every number, axis, cost basis and per-task outcome; it carries no rank number. Which rows this applies to, and why: Honorable mentions — services built on another entrant's model.
v1.4 scores are not comparable with v1.3 or earlier (sealed blend, gap penalty and harmonic mean). The v1.3.0 board stays below as history; the v1.0 page keeps its own numbers, calibration plots and per-family tables.

Authors: if we tested the wrong configuration, tell us and we will rerun it. New entrants become a new version rather than silently changing this one.
