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).
๐ป 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.
๐ฆ 360 GB โ 111 GB (4-bit GGUF, 4 files) ๐ฅ๏ธ No GPU: one server CPU (16 threads) at 18.4โ21.0 tokens/s ๐ป RTX 5060 laptop (8 GB VRAM) + 32 GB RAM: 4.17 tokens/s ๐ง 128 GB mini PC: whole model in memory, no GPU needed ๐ฏ MMLU-Pro, 2,000 questions, paired: original 87.65% = 4-bit 87.65%
How? ยท Only ~3B of 180B parameters are active per token (10 of 512 experts) ยท llama.cpp streams just the needed experts from SSD, so 32 GB RAM is enough ยท 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.
