Jev-class = cost per decision at most 2× Jev 1.13.0's (≤ $0.065 per 1,000 decisions) and median latency at most 2× Jev 1.13.0's (≤ 1.23 s, the adjusted p50 — the same median the speed chart plots, not the four-axis Speed score). 55 of 98 systems qualify; the other 43, including the general-purpose LLMs, are listed below the divider in the ranking. The charts below show speed and cost beside Capability; the official JevBench Score weighs all four axes.

Capability against cost and speed

Jev-class systems are shown by default. Bubble size follows the official JevBench Score. The five most capable Jev-class systems are labelled.

Capability vs cost

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.

Capability vs speed

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). The dashed line is 2× Jev’s median latency.

Cygnet and Winnow-12B Q8 are joint leaders (statistical tie).

Whiskers are 95% bootstrap intervals. 74 of 83 adjacent pairs with published paired-bootstrap comparisons are statistical ties — read the order as a ranking, not the gaps as significant. No paired comparison is published for the other 14 adjacent pairs, so no tie classification is inferred.

Greener = stronger within its column.

Weights:
Adjust weights ↓

Weights are relative: each axis counts in proportion to its slider. The score stays a weighted harmonic mean with the low-axis gates; the gates still apply when an axis sits at 0. 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)

I, C, S, K = Intelligence, Calibration, Speed, Cost; the est. pill = estimated cost; ann. = announced price; API = the operator's endpoint saw sealed item text, without answers; $/1k decisions = US dollars per 1,000 decisions (not heat-shaded). Names link to each project.

Honorable mentions and Jev wrappers — listed separately, not ranked (1)

Eligibility rule: services that run on Jev itself may be measured and shown as honorable mentions, but are not competitors ranked against Jev and do not enter the field median gap (G_med) or tie markers. classifier.dev (TypeSafe) runs on Jev, so it stays unranked under this rule.

  • classifier.dev (fast tier)APIhonorable mention: runs on Jev (TypeSafe) - listed, not ranked (honorable mention, as in v1.4.2). Official (A) score 74.7.

Compare two systems

Pick any two. Four radars: the score axes, chance-corrected competence per request type on the open and sealed sets, and competence per tier on each set. Further out is better on every spoke; the link keeps the pair.

Axes, request types, latency and cost

Compare:

Every measured system, under the four score axes. Intelligence is 50% open (904 decisions) and 50% sealed (720); Gap = I_open − I_sealed, and the penalty applies only above the field median gap (G_med 5.2) plus 8. The per-type competence, latency and price of the same systems are in Types & cost. On a phone the name column stays put while the table scrolls sideways.

Cygnet and Winnow-12B Q8 are joint leaders (statistical tie).

Whiskers are 95% bootstrap intervals. 74 of 83 adjacent pairs with published paired-bootstrap comparisons are statistical ties — read the order as a ranking, not the gaps as significant. No paired comparison is published for the other 14 adjacent pairs, so no tie classification is inferred.

All three weight options (98 systems)

All three weight options

A is the official headline: equal 25/25/25/25 axis weights and an Intelligence floor of 50. B remains the secondary 40/20/20/20 axis-weight view; C retains equal axes with an Intelligence floor of 60. All three use equal Choice/Noul/Score weights. The CI column is the paired-bootstrap 95% interval of the A score.

What the run says

  • Among the 55 Jev-class systems, Jev 1.13.0 has the highest Capability, 80.0 (Intelligence 72.0, Calibration 88.0).
  • Cygnet leads the official JevBench v1.5.1 score (option A) with 73.7: Intelligence 71.1, Calibration 87.0, Speed 91.0, Cost 56.4 ($0.028 per 1,000 decisions).
  • The best open or open-planned rebuild, Winnow-12B Q8, is #2 at 73.2 — 0.5 points behind.
  • GPT-6 Luna (default medium reasoning effort) has the highest Intelligence (96.2) but places #33: Speed 73.2, Cost 38.3 — the harmonic mean does not let accuracy buy back a weak axis.
  • The strongest sealed Intelligence is 98.2 (Qwen3.8 27B, #96); sealed items carry half of Intelligence, and an open-minus-sealed gap beyond the field median plus eight points costs Intelligence.
  • 74 of 83 adjacent pairs with published paired-bootstrap comparisons are statistical ties — read the order as a ranking, not the gaps as significant. No paired comparison is published for the other adjacent pairs, so no tie classification is inferred.
  • All 9 systems joined by separately hashed roster addenda and have official ranks in this revision; their A/B/C ranks and intervals are in the addendum table below.
  • classifier.dev scores 74.7 but is not ranked: runs on Jev (TypeSafe) - listed, not ranked (honorable mention, as in v1.4.2).
  • SimpleJev Qwen3.6-35B-A3B did not complete the full suite; they are listed without a rank.

Jev alternatives, open source and self-hosting

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.

What are open-source alternatives to Jev?

The highest-ranked open entrants in this run are Cygnet (#1, 73.7), Winnow-12B Q8 (#2, 73.2), JevK5 v0.3 (#4, 71.9), Plumb-4B (#5, 71.6). “Open” here means the tested row publishes code or weights; check the licence and exact configuration in the board before adopting one.

Which Jev-class models can I self-host in the EU or use for GDPR-sensitive work?

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.

How is JevBench scored?

The official score (option A) is the equal-weight harmonic mean of Intelligence, Calibration, Speed and Cost — 25/25/25/25 — with an Intelligence floor of 50 and low-axis gates on Speed and Cost. Version v1.5.1 measures 904 open and 720 sealed decisions per system; Choice, Noul and Score each carry a third, sealed items contribute 50% of Intelligence, and an open-minus-sealed gap beyond the field median costs points. Method notes · options B and C.

How do I submit my model?

Open an issue in the JevBench repository with a reproducible endpoint or runnable code, the exact model and licence, and whether public JevBench items were used during development. New entrants use the same frozen harness and appear in a new version or a disclosed roster addendum. For private data, see the custom evaluation options.

What a decision costs

Every price here is US dollars per 1,000 decisions — not per 1,000 tokens. One decision is a whole typed request — state, rubric and options — not a single token.

How costs are estimated

Systems with a public tariff (per token or per request) are priced at that tariff times the tokens we measured — 3 rows carry a tariff. Systems without one — open weights, author demos, models we ran ourselves — are priced as if a large inference provider hosted them: the list price of the same weights, or the nearest larger sibling or size class when the exact weights are not listed. 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 (v1.5). Only public, bookable list prices that have been in effect for at least 30 days count; a manufacturer's standard, non-promotional launch list price counts from day one, and promotions, subsidies, credits and free tiers never do. The scoring price is never below the market reference price of the system's base model. A system without any eligible price is listed as unpriced — no Cost axis and no score until a price qualifies. A later price change triggers a re-score with a visible note on the row.

Roster addendum: newcomers scored on the same frozen protocol (9)

All 9 A1/A2 systems below completed all 1,624 decisions and now have official ranks in A, B, and C; the interactive score presets also include them. Their scores, individual 95% intervals, and the frozen v1.5.0 G_med are unchanged. No new paired-bootstrap comparisons were computed for addendum systems. Existing tie markers are retained only for base-system pairs that remain adjacent; no tie or separation is inferred for the other pairs.

Ranks follow option scores; score intervals are per system, not pairwise rank comparisons. Every slider preset sorts these same ranked systems using its selected weights.

Not ranked: partial, unpriced and unmeasured systems

These systems are part of the 103-system v1.5 roster but have no rank. Their numbers are never shown as zero or free.

Partial runs (1)

  • SimpleJev Qwen3.6-35B-A3BAPIpartial run: Partial run: 677 of 1,624 decisions answered; the missing ones count wrong and the row is not ranked.

Incomplete or not measured in v1.5 (3)

  • Jobe Qwen3.5-4B (frozen): not measured.
  • mica-v01-4bv1.5 roster addendum A1: The frozen refusal policy stopped the run after 1,088 of 1,624 rows: 27 documented refusals were mapped to HTTP 422, then three consecutive passthrough HTTP 400 refusals triggered exit 6. The remaining 536 rows have no scores, so this system is not eligible for an official rank. (1,088/1,624 rows; 536 missing).
  • OpenJev (DiffusionGemma 26B-A4B NVFP4, razorback16): not measured.

Incomplete and unmeasured systems receive no official rank. Existing results from earlier benchmark versions remain on their frozen version pages.

Method notes: what changed in v1.5

The four axes

Intelligence · 25%
How often answers are right above chance: each type is normalized against its task-specific random baseline (chance = 0, perfect = 100; below-chance tiers can be negative). Choice, Noul and Score count one third each. Easy, Standard, Judge and Hard items count 10%, 20%, 30% and 40%; the open and sealed sets count equally.
Calibration · 25%
How closely stated probabilities match what happens. It uses ECE and TVD for Choice, ECE and Brier for Noul, and normalized RPS plus top-level ECE for Score. The three types count equally; open and sealed items are pooled.
Speed · 25%
Serial response latency on open Standard and Judge items. The p50 and p95 each get a log score: 100 − 20 × log₁₀(seconds ÷ 0.1), then are averaged. Self-hosted and demo endpoints get the published ×2 plus 0.15-second adjustment.
Cost · 25%
Estimated or billed US dollars per 1,000 decisions, using pooled token use across 1,624 decisions and the documented price rules. The log score is 100 − 30 × log₁₀(cost ÷ $0.001). The price reference is $0.001 per 1,000 decisions.

The official score is the weighted harmonic mean of the four axes. Option A gives each axis 25%; option B (40/20/20/20) is a secondary view, while option C keeps equal axes and sets the Intelligence gate at 60. In A and B, Intelligence, Speed and Cost each have a quadratic gate below 50. To limit benchmaxxing on the public items, the open-minus-sealed Intelligence gap may be up to 8 points above the field median (G_med) before a penalty applies. Each further point lowers the multiplier on unpenalized Intelligence by one percentage point.

Frozen method METHOD-v1.5, SHA-256 c25d3d8b8512…; pricing addendum v1.5-M2, SHA-256 2fc44459ef80….

The method owner chose equal axis weights and equal weights for Choice, Noul and Score after reviewing the What-If Lab, preserving continuity with v1.4 and treating the three decision types equally. Disclosed headline amendment: equal-axis, equal-type A, SHA-256 752ddccc4e19…. B remains a secondary view.

  • 1,624 decisions per system: 904 open (601 published) and 720 sealed, drawn fresh from a private pool with the same tier mix as the open set. Sealed counts for 50% of Intelligence: base = 0.5 × I_open + 0.5 × I_sealed.
  • Three request types are scored natively and chance-corrected per item: Choice, Noul and Score each receive one third. Tier weights easy / standard / judge / hard = 10 / 20 / 30 / 40. A type a system does not support is excluded, never scored zero; only full-coverage systems are ranked.
  • Overfit penalty relative to the field: excess = gap − G_med, penalty = max(0, 1 − max(0, excess − 8) / 100). G_med for this batch is 5.2 CC points.
  • Calibration is typed (Choice ECE/TVD, Noul ECE with Brier, Score normalised RPS and top-level ECE), pooled over open and sealed. Speed and Cost formulas are unchanged from v1.4; self-hosted and demo endpoints carry the ×2 + 0.15 s adjustment. A manufacturer's standard, non-promotional launch list price counts from day one, but a newer price cut younger than 30 days does not. Rows without token counts use the measured proxy-token basis. A system without any eligible public, bookable price is listed as unpriced.
  • The frozen 25 Sep DeepInfra snapshot records Qwen3.5-4B as deprecated on 11 Jun 2026 and replaced by Qwen3.5-9B. Its frozen snapshot rates remain the v1.5 M2 reference; price basis tooltips and the correction note disclose this. Pricing disclosure correction SHA-256: 1b660648bd49….
  • Composite: weighted harmonic mean with the Intelligence, Speed and Cost gates below 50 (Intelligence below 60 in option C). The official headline A uses equal 25 / 25 / 25 / 25 axis weights and Intelligence floor 50. B remains the secondary 40 / 20 / 20 / 20 view; C keeps equal axes and Intelligence floor 60. Ties come from the paired bootstrap.
  • The nine full-coverage systems marked with a v1.5 roster addendum label are officially ranked in A, B, C, and every score preset. Their scores, individual intervals, method, pricing rules and frozen G_med are unchanged. No new paired-bootstrap comparison is inferred for addendum pairs.
  • Before every release we review the leaderboard for anomalies and close loopholes with general, documented rules. The page and Git repository provide transparent data and method details; Benchmark Heaven owns its rules.

Limits
  • 1,624 decisions per system (904 open, 720 sealed) is a measurement, not a census, and it is English-only.
  • The weights are a choice. Option A weights the four axes equally and uses a harmonic mean, so the weakest axis dominates; options B and C are published alternatives and the weight sliders re-score the same axes for exploration — only the official option gives the official score and rank. If a wrong decision costs you more than a slow or expensive one, read the Intelligence column and the per-type competence rather than the score alone.
  • The latency adjustment (×2, +0.15 s on our own servers and demo endpoints) is an assumption, not a measurement. We ran the self-hosted and demo endpoints one request at a time (parallelism 1, no other load), so their latency is likely better than the same model on a busy production server. Serving under load trades per-user speed for throughput. The +0.15 s stands for infrastructure our self-hosted tests lacked: authentication, load balancing, logging, billing and an API gateway. Both numbers are assumptions; raw p50/p95 latencies are in the table and the repo.
  • Held-out decisions are sent to the evaluated services to get predictions. Not public is not the same as not seen.
  • Latency is one origin at one time of day; hosted endpoints, public demos and our own pods are different kinds of latency. Public demo endpoints are shared with everyone else using them.
  • Estimated costs describe what a large inference provider would charge for a model of that size, not what the author pays; a system on a tariff pays its tariff.
