About

Meta Superintelligence Labs builds Muse Spark, a coding-optimized model with a one-million-token context window, visual input, and reliable tool calling — built for long agent sessions that keep repository state across turns.

On Brainbase, Muse Spark is platform-billed ($1.25 in · $4.25 out per 1M tokens, $0.15 cached input) and runs inside any open harness — Codex Agent, OpenCode, or Qwen Code — selected per task like any other platform model.

Available on Brainbase:

  • Muse Spark: Meta Superintelligence Labs' first model family; the Brainbase id tracks the current 1.2 release, including Muse Spark 1.2

Run these models in Codex, OpenCode, or Qwen Codeselected per task like any other platform model.
