Darwin-180B-RSI

VIDRAFT, a Korean AI company, put Darwin-180B-RSI on Hugging Face on 28 September 2026 as an open-weight reasoning model. It is a fine-tune of Alibaba's Qwen3.8-Flash-Next and reads both text and images. Its results are the developer's own, and no independent evaluation had been published when the sources were read.

Features

• Reasoning on text and images: keeps the parent model's vision encoder and a context of about 262,000 tokens.
• Self-checked training: the model solves practice problems and keeps only answers that match an answer key, then retrains on them.
• Confidence readout: a score given before the answer estimates the chance it is correct, letting an application escalate or decline.
• Shorter reasoning: the developer reports reasoning about 11 per cent shorter than its parent, which reduces the work needed per answer.
• Self-hosting: the model card describes serving it with vLLM and names no hosted API.

Who it serves

Teams that can host a 180-billion-parameter model themselves and want a reasoning model that reports its confidence before it answers.

Key facts

• Developer: VIDRAFT, a Korean AI company.
• Size: 180 billion parameters on the model card, although press reports disagree on the figure.
• Parent model: Alibaba's Qwen3.8-Flash-Next.
• Licence: Qwen Community License 1.0, which a business should read before commercial use.
