Meta’s Muse Spark 1.1 AI promises faster smarter agent workflows

Meta has introduced Muse Spark 1.1, an advanced AI model focused on improving intelligent agents and programming for complex multimodal tasks. Unlike its predecessors, it is not open-source, aligning with Meta's shift towards closed-source commercial models. The model enhances agent capabilities, reducing latency in multi-agent systems and intelligently managing workflows across applications.

Coding performance is moderate, achieving a score of 61.5 on the SWE-Bench Pro evaluation, which is better than some models but less than others like Claude Opus 4.8. Muse Spark 1.1 is available through the Meta Model API with specific pricing for token usage and is currently limited to developers in the U.S.
