Muse Spark 1.1 is the July 2026 upgrade to Meta Superintelligence Labs’ Muse Spark series. It is a multimodal reasoning model specialized for agentic tasks, delivering major gains in tool calling, computer use, coding on large codebases, and multimodal understanding (images, video, PDFs). The model supports a 1-million-token context window that it actively manages across extended sessions and multi-agent orchestration. It is available in Thinking mode on meta.ai and via the new public-preview Meta Model API.
