Muse Code: Async Agents That Survive a Crash

Meta just entered the coding-agent wars

On August 5, 2026, Meta Superintelligence Labs shipped Muse Code, a terminal coding agent, together with Muse Spark 1.2, a model co-trained with the agent that drives it. Within 48 hours it was the loudest developer story of the week: VentureBeat framed it as Meta entering the coding-agent wars against Claude, GPT, Gemini, Grok and Kimi, and the launch trended across r/LocalLLaMA and Hacker News. The hook that got everyone talking is not a benchmark number. It is that a Muse Code session can run for 24 hours across 1,000+ tool calls and survive a crash without losing its place.
