π 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.
π Top of the board π₯ Darwin ZTC v2 (FINAL-Bench) 89.58 π₯ OpenJev-27B 87.50 π₯ AutoJev-27B 87.07 4οΈβ£ Eikos 27B 85.43 5οΈβ£ Jev 1.13 85.05
π 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.
βοΈ Why a zero-token judge wins here πΉ It does not generate. It reads the input and typed questions and returns a calibrated distribution in a single forward pass. πΉ Zero generated tokens, no decoding loop, so latency and cost stay low. πΉ 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.
π» Data-center AI, now on a laptop: POCKET-Darwin-180B
We're releasing a 4-bit GGUF build of Darwin-180B-RSI, #1 on seven official Hugging Face leaderboards (self-reported), that runs without a GPU.
π¦ 360 GB β 111 GB (4-bit GGUF, 4 files) π₯οΈ No GPU: one server CPU (16 threads) at 18.4β21.0 tokens/s π» RTX 5060 laptop (8 GB VRAM) + 32 GB RAM: 4.17 tokens/s π§ 128 GB mini PC: whole model in memory, no GPU needed π― MMLU-Pro, 2,000 questions, paired: original 87.65% = 4-bit 87.65%
How? Β· Only ~3B of 180B parameters are active per token (10 of 512 experts) Β· llama.cpp streams just the needed experts from SSD, so 32 GB RAM is enough Β· Graft quantization: we took the proven Unsloth UD-Q4_K_XL base build and swapped in only the 300 tensors our RSI training changed (300/300 verified)
Under the hood is Model-level Recursive Self-Improvement. The model solves verifiable problems, keeps only its own solutions that check out as correct, and trains on them. No human-written solutions or reasoning traces.
Built for teams that can't send data to an external cloud (defense, finance, public sector) to run a top-tier model fully offline.
𧬠Darwin-180B-RSI β an AI that learns from itself and knows when it's right π FINAL-Bench/Darwin-180B-RSI
𧬠Darwin β crossbreed and evolve the parent Darwin diagnoses strong parent models like an MRI, inherits only their best parts, and evolves the weak spots β producing a child stronger than its parents. Father model: Qwen3.8-Flash-Next (180B MoE).
π RSI Γ ποΈ ZTC RSI (recursive self-improvement): solve β verify against real answers β learn only the correct reasoning β repeat. ZTC (Zero-Token Confidence): reads the model's internal state once, before answering, and returns the probability the answer is right β zero extra tokens. Returns answer + confidence as JSON. {"answer": "...", "confidence": 0.97, "truncated": false}
β¨ Synergy: ZTC finds where the model wavers β RSI learns exactly there β confidence gets sharper. Low confidence = stop, so agents don't act on wrong answers. β‘ Same accuracy, 11% shorter reasoning β faster and cheaper.
