	tl;dr: Muse Code is a new terminal coding agent (beta) for macOS/Linux that handles complex tasks across large repositories using persistent async subagents and a replay-exact event log for crash recovery. It's powered by Muse Spark 1.2, a coding-focused model co-trained with the agent and optimized for long-horizon tasks like whole-repo generation and iterative GPU kernel optimization over 1,000+ tool calls. The model is available now via Muse Code and the Meta Model API.
	HN Discussion: ~Meta's discounted 'contributor' pricing for training data access is notable but raises privacy concerns ↓Benchmarks are marketed misleadingly by comparing against weaker competitors and still losing ↓Distrust of Meta accessing user code, even open source, limits adoption appeal ↓The model isn't truly capable since Meta can't even use it to port Muse Code to Windows ↑The built-in orchestrator/subagent pattern in Muse Code is the genuinely interesting innovation
