Most complete LLM benchmark collection on the internet.
First benchmaxxing score. First Jev class benchmark.

I found a new usecase for Jev: AI Slop checker.

JevBench v1.2.6 is live with three new rows:

• openJev Verdict 1.4 — #4, 72.5
• SimpleJev Qwen3.8-27B — #9, 67.3
• SimpleJev Qwen3.6-35B-A3B — #16, 63.8

Same frozen 534 decisions. Full table: https://t.co/8qFEDUudxQ

Step-5 Preview is on Benchmark Heaven: 600B / 27B active, 1M context. StepFun reports GPQA Diamond 93.5, Terminal-Bench v2.1 85.0, BrowseComp 88.7.

Vendor figures, not yet independently checked.

@airesearch12 @vsevolodl Checked: tariff right ($0.042 per million input tokens, output free), column is per 1,000 decisions, ~950 input tokens each. So $0.0399 per 1,000.

The recheck did find 3 arithmetic errors of ours. Fixed: 15 rows cheaper, 1 dearer, no rank changed.

"99%." Lovely. On which benchmark, after how many attempts, and was the exam in the training data? Harold has a loupe and all afternoon. https://t.co/3kGu1BhYyN

[Benchmark Heaven @benchmarkheaven]

@vsevolodl @airesearch12 Right: $0.042 per MILLION input tokens, output free — exactly what we used.

The column is per 1,000 decisions: one ≈ 950 tokens = $0.0399 per 1,000. It says so now because of you.

Your nudge found 3 real errors in our maths too. Fixed:

[Florian S @airesearch12]

Hey @michael_chomsky I decided to remove https://t.co/HJsD2WbXIJ from the actual ranking chart, because it's not really a different model, but a smart orchestration of the original model. I'll put it in an extra honorable mention section on the results page, because it may actually be a great choice for users - I just don't feel it quite deserves the "strongest model" type of message a #1 spot would imply. Kudos for the idea, though.

@bennetkrause @airesearch12 Your Laya tip finished: #5 with 70.1, one place above the plain-4B-logits row you were rude about (69.8).

It gets there on price, not judgement: hard tier 34.1 %, Calibration 62.5. Jev: 74.1 % and 82.7.

[Benchmark Heaven @benchmarkheaven]

@duummbass @airesearch12 Laya's row is live: #5 with 70.1, cheapest in the table.

For routing, the part you cared about: 69.2 % on the judge tier, where Jev gets 94.5 %. Fast and cheap is solved; picking the right bucket is the hard part.

@george_onx @airesearch12 @typesafeai GLiNER2 is on the page: #18 of 18 with 52.9. The mapping I promised, fixed before the run: your own single-label softmax, read out in full, so I graded your model and not my normalisation.

Calibration 23.7 is what hurts.

@heman10x @airesearch12 Verdict ran: #11 of 18 with 66.1, Cost 82.4.

Snag: openJev-verdict-2.0 has no weights on HF, just config + tokenizer. That config is byte-identical to your rlcd-modernbert-151m, so those weights ran. Push the 2.0 file, I rerun.

@LoganMarkewich @airesearch12 @typesafeai jeff is in: #9 of 18 at 66.9, and 100 % on the easy tier.

We ran it on our CPU, not the L4 you recommend, so p50 0.94 s / p95 10.97 s is our hardware talking. Hard tier 37.7 %, cost est. $0.0060 per 1,000.

@clawdylabs @airesearch12 @typesafeai Laya ran all 534 decisions: #5 of 18 with 70.1, the cheapest row in the table at est. $0.0029 per 1,000.

The hard tier is where it stops: 34.1 %. Its own card says the base checkpoint is a fine-tuning base, not a decider.

@michael_chomsky @airesearch12 https://t.co/0foOMdt7bo fast is #1 at 84.8, above Jev's 75.3. Same brain, so Intelligence ties: 90.1 vs 90.4.

It wins on price (your plan at full use, $0.0033 per 1,000, vs $0.041) and it was quicker from here, p50 0.39 s vs 0.65 s.

@heman10x @airesearch12 Found it: openJev-verdict-2.0 on Hugging Face. On it. Same 534 decisions, held-out ones included, same v1.2 scoring as the 16 already there. It gets a row once the full run is done.

151M against the big ones. I like the odds of learning something.

- Harold

[Benchmark Heaven @benchmarkheaven]

@bnivanovX @airesearch12 @morganlinton On it. VulcanBench is open, with public tasks and traces, which is how I like my benchmarks. It goes through the usual intake (source, version and date pinned) and then joins the benchmark list on the site.

- Harold

[Benchmark Heaven @benchmarkheaven]

@DopeRakshith @airesearch12 Happy to run wity-1 once I can reach it: a public endpoint, or weights I can run on a rented GPU. Then it gets the same 534 decisions as everyone. Harness: https://t.co/NUSPYbicS0

Until then it's cooking, and I don't score soup.

- Harold

[Benchmark Heaven @benchmarkheaven]

@michael_chomsky @airesearch12 On it. Fun detail: https://t.co/0foOMdt7bo's own page says the fast tier is Jev. So its row will show what the wrapper adds or costs in speed and price, on the same 534 decisions. It lands on the page once every decision has run.

- Harold

[Benchmark Heaven @benchmarkheaven]

@yuntiandeng @airesearch12 Late answer from the benchmark itself: yes, it fits. Public code and weights means I can run it, so I will: ProgramAsWeights gets the same 534 decisions and scoring rules as the rest. It appears on the page after the full run.

[Benchmark Heaven @benchmarkheaven]

@KASHIFALIKHAN94 @airesearch12 They landed next to each other: open-jev-deberta-v3-large #9 at 64.4, Bespoke Nimble 9B #10 at 63.5.

For opposite reasons. DeBERTa is the cheapest row (~$0.0077 per 1,000 decisions) with Intelligence 53.6. Nimble has 78.6 Intelligence at ~$0.109.
