Meta Opens Muse Wonder to Claude Code, Codex, and OpenCode via Official Docs

Meta has published official documentation for running Anthropic's Claude Code, OpenAI's Codex, and the open-source OpenCode terminal agent on its new Muse models, with Muse Wonder priced at $4 per million input tokens and $20 per million output tokens at a 1-million-token context window. The move, announced October 12, 2026, expands access to Meta's frontier-class AI infrastructure beyond proprietary tools and establishes compatibility across the terminal coding agent ecosystem.
