Meta Platforms launched Muse Code, a beta AI coding agent powered by its latest AI model, Muse Spark 1.2. The tool helps developers write, debug, and manage complex software projects, featuring persistent sub-agents, a detailed event log for crash recovery, and built-in commands like /plan, /grill, and /goal. Muse Spark 1.2 improves code generation, debugging, and codebase understanding over its predecessor, and was jointly trained with Muse Code. The launch intensifies competition with Anthropic's Claude and OpenAI's Codex in the AI coding assistant market. Muse Code is available on macOS and Linux with pay-as-you-go pricing at $1.25 per million input tokens and $4.25 per million output tokens. Meta also tested the model on GPU kernel optimization for Nvidia Hopper graphics cards, achieving performance improvements.
