Open-weights Muse Spark powers a browser computer-use agent — full HF tutorial shipped
mervenoyann · x · 2026-10-19
mervenoyann shipped an end-to-end tutorial for building a browser agent environment using open-weights Muse Spark (including NVFP4) as a computer use agent, built with OpenEnv, Helium and Hugging Face Sandboxes.
- Helium Browser Environment wraps a Chromium browser: clients send typed actions one at a time, the environment executes via Helium + Selenium and returns observations with fresh screenshots and URLs
- The recipe adapts to any model; notably a truly multimodal agent that doesn't use browser state for decisions
- Includes a visualized demo run and full documentation
