Muse Code: Meta Attacks Claude Code and Codex, Targeting Developers

Meta has entered the competitive AI coding assistant market with Muse Code, announced on August 5, positioning it as a direct rival to Anthropic's Claude Code and OpenAI's Codex. The autonomous agent, available in beta, can break down entire projects into tasks, write code, and self-verify quality, while also coordinating multiple sub-agents for parallel work—a feature highlighted by Mark Zuckerberg. Pricing is consumption-based at $1.25 per million input tokens and $4.25 per million output tokens, with a tenfold discount for users who allow their usage data to train future models. This aggressive strategy is part of Meta's broader push to become a major AI player, following its investment of over $14 billion to acquire 49% of Scale AI and appoint Alexandr Wang to lead Meta Superintelligence Labs.
