Meta has launched Muse Code, a terminal-based AI coding agent powered by the Muse Spark 1.2 model, competing directly with Anthropic's Claude Code and OpenAI's Codex. The key differentiator is aggressive pricing: $1.25 per million input tokens and $4.25 per million output tokens for standard tier, with a contributor tier priced at $0.10 and $0.20 respectively—substantially cheaper than Anthropic's Sonnet 5. For enterprises processing large volumes of code daily, this cost advantage could drive significant migration from competitors, making pricing the primary competitive lever.
