Developers building computer-use agents with long context can use it, though Spark 1.3 has since replaced it at the same price.

Kenning's take

What it does

Muse Spark 1.1 is a multimodal reasoning model for agent tasks that can manage a context window of 1 million tokens, compacting earlier work while keeping the important steps. Meta says it is better at computer use across several applications and at work on large codebases. It launched in Thinking mode in the Meta AI app and on meta.ai, and through the Meta Model API in public preview.

  • 1 million token context window with active compaction
  • Computer use across multiple applications
  • Better work on large codebases
  • Image, video and audio understanding

Who it suits. Developers building agents on Meta's models, and Meta AI users of Thinking mode.
