Meta just made its play for the AI coding agent wars. The company has officially launched Muse Code in beta, moving the tool into direct competition with Anthropic’s Claude Code and OpenAI’s Codex.
Powered by the Muse Spark 1.2 model, Muse Code is a terminal-based AI coding agent built for complex software engineering tasks. It handles planning, code modifications, testing, and multi-agent coordination through persistent background sub-agents, all from the command line.
Pricing designed to undercut the competition
The standard tier charges $1.25 per million input tokens and $4.25 per million output tokens through the Meta Model API. A “contributor” tier is priced roughly 10 to 20 times cheaper than the standard option. The catch: you grant Meta permission to use your usage data for model improvements.
The API itself is designed to be compatible with existing SDKs from OpenAI and Anthropic. Installation is available via command-line for macOS and Linux users.
