Meta released Muse Code, a beta command-line coding assistant, together with Muse Spark 1.2, a coding-focused update to its proprietary model. The cheapest pricing tier costs a fraction of the standard rate but grants Meta permission to train on the code and prompts sent to it, so teams with confidential codebases must choose the dearer tier. Meta's own benchmark charts place the model second to Anthropic's Claude on all three tests shown.

What changed

Meta's developer offering centered on freely downloadable Llama weights, with no coding agent of its own.

What it unlocks

Running a terminal-based coding agent from Meta that keeps helper agents alive through a session, works on parallel isolated copies of a repository, and resumes exactly where it stopped after a crash.

  • contributor tier $0.10/$0.20 per 1M tokens
  • standard tier $1.25/$4.25 per 1M tokens
  • 60 vs 3,000 requests per minute
  • 82.9% Terminal-Bench 2.1

What you need to act on it

  • macOS or Linux
  • Meta account
  • payment method on file even for the cheap tier
  • opting into standard pricing to keep code out of Meta's training data
