OUI-1: open DiffusionGemma finetune for Generative UI (71.7%)

· opgehaald 21:15

Thesys/OpenUI released OUI-1, a 26B/4B-active DiffusionGemma finetune that emits openui-lang UIs at 71.7% on the Generative UI Benchmark (5.5× base), open weights on Hugging Face under Gemma terms, runnable on an RTX 5090 at FP8.

On 8 Sep 2026 OpenUI introduced OUI-1: SFT + parser-verified self-distillation on DiffusionGemma across 27 component libraries, lifting Generative UI Benchmark from 13% to 71.7% while recovering most of the base model’s speed. Weights are on Hugging Face (Gemma ToU); the team positions it for local, sub-second agent-driven interfaces versus cloud-only setups like AppLess on Cerebras.
