๐งฌ Darwin-180B-RSI โ an AI that learns from itself and knows when it's right ๐ FINAL-Bench/Darwin-180B-RSI
๐งฌ Darwin โ crossbreed and evolve the parent Darwin diagnoses strong parent models like an MRI, inherits only their best parts, and evolves the weak spots โ producing a child stronger than its parents. Father model: Qwen3.8-Flash-Next (180B MoE).
๐ RSI ร ๐๏ธ ZTC RSI (recursive self-improvement): solve โ verify against real answers โ learn only the correct reasoning โ repeat. ZTC (Zero-Token Confidence): reads the model's internal state once, before answering, and returns the probability the answer is right โ zero extra tokens. Returns answer + confidence as JSON. {"answer": "...", "confidence": 0.97, "truncated": false}
โจ Synergy: ZTC finds where the model wavers โ RSI learns exactly there โ confidence gets sharper. Low confidence = stop, so agents don't act on wrong answers. โก Same accuracy, 11% shorter reasoning โ faster and cheaper.

Run it on defaults and it takes 244 s. Switch to 3 steps and it's 48.6 s. Add VAE tiling and it's 46.4 s.
The biggest culprit was the default. Z-Image Turbo is distilled to paint in few strokes, but the tool's default is 20. We were throwing away 5ร for no reason. So were we, at first.
3 is the floor. Put 4 and 3 side by side and you cannot tell them apart. At 2 it collapses โ water droplets and wood grain vanish, and the surface turns cloth-like.
The cost of a judging gate is usually quoted as a number. This puts it on a Tetris board.
Three boards get the same piece order, and on every move the same proposal and the same noise โ a paired comparison. The gate decides one thing: keep this move, or draw again. Each board gets the same 60 seconds of gate time.
The text-writing gates get through 15โ22 moves. The generation-free gate gets through 40โ50. The boards that stop simply run out of clock.
It does not win on accuracy: on the same 2,018-question LODO set, JEV scores AUC 0.7350 against ZTC-Judge-27B's 0.7289. The separation is elsewhere. Clock โ 2.1 s vs 0.0615 s per call, and on a 200-candidate agent screen one judging call measured 3.206 s generative vs 0.033 s readout, same server. Calibration โ a gate is a threshold, and at ECE 0.4985 (vs ZTC 0.0245) a threshold stops carrying information. Mechanism โ a text judge can name option 42 when there is no option 42; a scoring readout cannot. Not a lower error rate. No path.
The curve in the ZTC panel is real online fitting, scored prequentially โ predict first, learn after โ with base weights untouched. Not recursive self-improvement.
Limits, also stated on the page: Laya's AUC and latency are not our measurements and are set equal to JEV's, so calibration is the only measured axis it differs on. The page is a simulation driven by measured constants.
