Meta releases Muse Code terminal coding agent and Muse Spark 1.2 model

Muse Code and Muse Spark 1.2

Meta launched Muse Code (beta), a terminal agent for complex software engineering, paired with the coding-focused Muse Spark 1.2 model. Persistent background subagents cut redundant info gathering, and a local event log enables exact crash recovery. The model leads on Terminal-Bench 2.1 and DeepSWE 1.1, and a case study shows 24-hour GPU kernel optimization. The post doesn't mention pricing or open-source plans.

Why it matters: Meta shipped a terminal coding agent with parallel sub-agents and checkpoint resume — real engineering improvements. No pricing or internal model comparison data disclosed, so it stays below 85.
