New Release: Darwin-60B-DUO: Two SOTAs, One Endpoint — 88.38% on GPQA Diamond
We're excited to release Darwin-60B-DUO, the Darwin family's first DUO model. Take two domain-verified specialists, hide them behind a single OpenAI-compatible endpoint, and let a router decide which one (or both) answers. You see one model, one API — but get the best of both.
The number that matters: on the full 198-question GPQA Diamond, Darwin-60B-DUO hits 88.38%. The constituents alone land at 69.70% (Darwin-28B-REASON) and 77.27% (AWAXIS-Think-31B); a naive cascade only reaches 83.84%. The DUO clears them all. Two small specialists, intelligently routed, beat one big generalist on cost and quality. Both are independently verified — Darwin-28B-REASON is #3 on the HF GPQA Diamond leaderboard, AWAXIS-Think-31B is #1 on Korea's national K-AI Leaderboard (MSIT).
The brains is a Hybrid-A router picking one of five strategies on the fly. Korean → AWAXIS, English/STEM → Darwin (single-backend, ~70% of traffic at 1× cost). When a Korean answer needs rigorous English reasoning, split_refine fires — Darwin drafts, AWAXIS polishes; MCQ/short-answer runs both with self-consistency + cross-verify. Net effective cost: only ~1.3× a single 30B model.
The part the community will care about: the gateway is model-agnostic and Apache-2.0. Point it at any two OpenAI-compatible backends and you've got a DUO in minutes — teach router.py when to use which, and parallel calls, response merging, and routing transparency via _duo_route are handled for you. Fork it and tell us what you built.
Painless deploy: docker compose up for both vLLM backends + gateway; FP8 30GB colocates on a single B200/H100. One git clone (120GB). Text-only for now, streaming in v1.1.

Looks like it's uploaded in an odd way? Is it the model in the subdirectory awaxis-31b?

Thanks for checking.
This repo is not a single standard model uploaded in the usual root layout. Darwin-60B-DUO is a DUO/router-style model that orchestrates two underlying 31B-class models. The awaxis-31b subdirectory is one of the routed component models, not the whole model by itself.
So yes, the structure may look unusual if you expect a single model at the repo root. The intended design is closer to a mixture-of-models / routed ensemble, with a custom DarwinDuoOrchestrator wrapper.
I’ll update the README to make this clearer and document which subdirectories are component models and how the DUO router is intended to load them.
