Muse Code

Meta is rolling out Muse Spark 1.3 in Muse Code and the Meta Model API for coding and agentic work. Meta says it uses about 20% fewer tool calls and 25% fewer tokens than version 1.2.

Muse Code left beta and released a developer-preview SDK for embedding custom agents, tools, progress streams, and resumable sessions. Its new workflows can split work among focused agents that pass intermediate context between sessions.
