Darwin-180B-RSI

180B Mixture-of-Experts · vision-language · GPQA Diamond 94.44 % — #1 on the Hugging Face leaderboard · self-improving

reasoning · MoE 512 experts · 262K long context · image + text · Korean + English · self-improvement · ZTC

The newest flagship of the Darwin family — #1 on GPQA Diamond, and a model that gets better by learning from its own verified work.

🧬 The Darwin Family

Darwin is VIDRAFT's measurement-driven reasoning model family — 50+ official models, 400+ community derivatives, and now two places in the GPQA Diamond top 3 (Darwin-180B-RSI #1 · Darwin-397B-ZTC #3).

🧬 Darwin — evolve the parent, keep what works

Darwin treats a strong open model as a parent. It measures where the parent is weak, and strengthens exactly those parts — instead of re-training everything and risking what already works.

Diagnose before you change. Every Darwin generation starts from a measured weakness map of the parent.
Change little, precisely. Darwin modifies a small, targeted fraction of the network. Knowledge stored in the experts is preserved.
Proven capability over new guesses. Earlier Darwin generations grafted the best-performing expert/FFN blocks from other strong models onto a base backbone; Darwin-180B-RSI adds a new ingredient — the model's own verified work.
Measured, not claimed. Every change must beat the parent on held-out tests before it ships.

Model	Scale	GPQA Diamond
Darwin-9B-NEG	9B	84.3
Darwin-27B-Opus	27B dense	86.9
Darwin-36B-Opus	36B MoE	88.4
Darwin-28B-REASON	28B + DELPHI	89.39
Darwin-397B-ZTC	397B MoE (FP8)	93.43

🔁 RSI — a model that improves from its own work

Recursive self-improvement (RSI) is the core of this generation. Instead of distilling a bigger teacher, the model improves by learning from itself:

Solve — the model works through practice problems it has never seen in evaluation.
Verify — its answers are checked against verifiable references (answer keys, executable checks). Nothing unverified is learned.
Learn — it is re-trained on the reasoning that turned out to be correct.
Repeat — the improved model becomes the next solver.

What it bought in this release:

	Parent (Qwen3.8-Flash-Next)	Darwin-180B-RSI
Average reasoning length (MMLU-Pro)	4,320 tokens	3,833 tokens (−11 %)
MMLU-Pro accuracy	88.04 %	88.12 %

Same or better accuracy with shorter reasoning — cheaper and faster to serve. Practice sets are deduplicated against every evaluation set we report (8-gram overlap filter).

🏛️ ZTC — it knows before it answers

Zero-Token Confidence (ZTC) reads the model's own internal state once, before generation, and returns the probability that the answer it is about to give is correct — no extra tokens, no second model.

{"answer": "...", "confidence": 0.93, "ztc_score": 1.84, "truncated": false}

Use it to gate actions: when confidence is low, do not call the tool, escalate, or answer "I don't know". The ZTC readout for this model is being fitted and will ship in ztc/ (same format as Darwin-397B-ZTC).

Chat Completions (OpenAI-compatible)

from openai import OpenAI
c = OpenAI(base_url="http://localhost:8000/v1", api_key="-")
r = c.chat.completions.create(model="FINAL-Bench/Darwin-180B-RSI",
    messages=[{"role": "user", "content": "Explain why the sky is blue in two sentences."}],
    temperature=1.0, top_p=0.95, extra_body={"top_k": 20})
print(r.choices[0].message.content)

Transformers

from transformers import AutoProcessor, AutoModelForImageTextToText
model_id = "FINAL-Bench/Darwin-180B-RSI"
processor = AutoProcessor.from_pretrained(model_id)
model = AutoModelForImageTextToText.from_pretrained(model_id, torch_dtype="auto", device_map="auto")

Tip: this is a thinking model. Give it room — a thinking budget of 32K–131K tokens is recommended for hard reasoning. Short budgets truncate the reasoning and cost accuracy.

⚠️ Limitations and disclosure

Scores are self-measured with the settings stated in the Results table; majority-vote numbers use several samples per question.
Very long reasoning is normal for hard problems; a short thinking budget will truncate answers and lower accuracy.
Like every LLM, the model can be confidently wrong — use the ZTC confidence readout to gate high-stakes actions.
