Meta released Muse Code in beta, a terminal-based coding agent powered by its Muse Spark 1.2 model that splits large engineering jobs into parallel sub-agents working in isolated worktrees. The company is pitching aggressive pricing ($1.25/1M input, $4.25/1M output tokens) against OpenAI's Codex and Anthropic's Claude Code, while some coverage has flagged data-privacy tradeoffs and observers question whether it actually outperforms rivals on real projects.
- Meta launched Muse Code, a terminal-based AI coding agent in beta, powered by its Muse Spark 1.2 model, that fans out work to parallel sub-agents in isolated worktrees.
- Meta is undercutting rivals on price ($1.25/1M input, $4.25/1M output tokens), positioning the tool against OpenAI's Codex and Anthropic's Claude Code.
- Coverage from The New Stack raises concerns that the low cost may come with data-privacy tradeoffs.
- Some commentators remain skeptical about whether Muse Code actually outperforms Claude or GPT-4 on real-world projects rather than just being cheaper.
