Meta's latest foundational model, Muse Spark 1.2, has achieved high scores in third-party performance analyses, demonstrating rapid improvement since the Muse series' debut four months ago. The model notably surpassed Grok 4.5 on the Artificial Analysis Intelligence Index and showed enhanced capabilities in agentic tasks, coding, and customer support benchmarks. Despite its strong performance and cost-effectiveness compared to competitors, Muse Spark 1.2 slightly trails behind top-tier models like Claude Opus 5 and GPT-5.6 Sol in certain advanced benchmarks.
