โ๏ธ The Open Quantum Challenge is live. Both seasons open today.
Quantum computers are expensive, queued, and reachable by only a few. So we removed the barrier. With a single GPU and a public harness, anyone can contribute to core quantum-computing problems with no quantum hardware at all. That is the point of this challenge: to move quantum research from a handful of labs to everyone.
โข Season 1, Quantum simulation: reproduce a target quantum system on a GPU. โข Season 2, QEC decoder: correct errors on coded quantum states.
Answers are held privately and every submission is auto-scored against a frozen ground truth, so the ranking is reproducible and hardware-independent.
๐ Prize: 2,000 USD total (1,000 USD per season, ๐ฅ600 / ๐ฅ300 / ๐ฅ100)
Getting started takes one step: copy the participation guide from the Space and paste it into Codex or Claude Code, then submit against the harness.
๐ง We just released Darwin-27B-ZTC, a judgment engine that reaches a verdict without generating anything.
Most LLMs answer by generating, decoding one token at a time. Darwin-27B-ZTC takes a different route.
โ๏ธ How it works ๐น It makes its call in a single forward pass. ๐น Zero generated tokens, and no decoding loop. ๐น That keeps latency and cost far below what a generative model needs.
๐ฏ What it judges ๐น It handles several question types: free-form correctness (noul), multiple choice (choice), and scoring (score). ๐น For each one it hands back a calibrated confidence, not just an answer.
๐ How well calibrated (measured) ๐น KL 0.204, Brier 0.097, so the confidence it reports lines up with what actually happens. ๐น 0.743 accuracy (zero-shot, general split), across 2,000 judgments with zero errors. ๐น By type: noul 0.847, choice 0.723, score 0.675. ๐น None of the benchmark's train split went into it. It is pure zero-shot.
๐ Where it fits ๐น Grading at scale, model routing, safety gating, anywhere you want a fast decision without paying for generation.
๐ It currently sits at #1 on the official typed-decisions leaderboard on Hugging Face (0.743 accuracy, zero-shot).
๐ Darwin-27B-ZTC-v2 just took #1 on the System One Mosaic Benchmark (S1MB).
S1MB compares 102 models across 137 specialized benchmarks, in three task types: Noul (assess a condition), Choice (select an option), Score (rate on a scale). Ranking is by overall Borda score.
๐ Top of the board ๐ฅ Darwin ZTC v2 (FINAL-Bench) 89.58 ๐ฅ OpenJev-27B 87.50 ๐ฅ AutoJev-27B 87.07 4๏ธโฃ Eikos 27B 85.43 5๏ธโฃ Jev 1.13 85.05
๐ Ranks 2 to 5 are all the JEV family (TypeSafe AI's System One model, from ex-OpenAI researchers). S1MB exists to compare these System One judges, so leading it is the headline.
โ๏ธ Why a zero-token judge wins here ๐น It does not generate. It reads the input and typed questions and returns a calibrated distribution in a single forward pass. ๐น Zero generated tokens, no decoding loop, so latency and cost stay low. ๐น Holds up out of distribution too: General Noul 96.00, General Choice 99.34.
It is also #1 on the typed-decisions leaderboard (0.743, zero-shot). Same message from both: a deterministic, calibrated judge at one forward pass per call.
