Meta released Muse Spark 1.3, an agentic coding model aimed at long-horizon work with usability features like sustaining long threads and confirming consequential actions. Meta reports it used about 20% fewer tool calls and about 25% fewer tokens than Muse Spark 1.2 in internal comparisons. The model is available today in Muse Code and the Meta Model API (with closed weights), improving coding efficiency and agent run behavior while self-hosting remains unavailable and top reasoning mode stays gated.
