Meta Muse Spark 1.2: 1M Token Window for Devs

Meta has released Muse Spark 1.2 and an early beta of Muse Code. Muse Code is Meta's first coding agent designed for complex software development. What's interesting is Muse Spark 1.2 offers a one-million-token context window. This allows developers to keep thousands of files and legacy code available in one session. The model is optimized for tasks like multi-file refactoring and extended debugging. Muse Code provides an auditable record of the agent's activity through a replayable event log. It can also break larger projects into tasks for parallel subagents, each in its own isolated Git worktree. This lets multiple agents modify code without interference. Meta is expanding global public-preview access to Muse Spark through Muse Code and the Meta Model API. Muse Spark 1.2 is also available via OpenRouter. The bottom line is these new tools aim to streamline and enhance multi-agent software development workflows.
