Muse Spark 1.2

Meta · Multimodal · Released Aug 2026

Muse Spark 1.2 is Meta's multimodal reasoning model that processes text and images together with a 1-million-token context window.

Strengths: Handles multimodal input and extended reasoning tasks across long contexts, supporting agentic and coding workflows.
Best for: Long-context multimodal reasoning, agent-based applications, and coding tasks where text and images are both inputs.
Limitations: Superseded by Muse Spark 1.3, released in September 2026; consider the newer model for production multimodal reasoning workflows.
