On August 6, 2026, Meta officially released its first AI programming agent, Muse Code, positioned as a low-cost alternative to Anthropic's Claude Code and OpenAI's Codex. Developed under the leadership of Alexandr Wang, Meta's head of artificial intelligence, the tool is built on the latest Muse Spark 1.2 model and optimized specifically for programming tasks. Muse Code operates via terminal command line, supporting complete software engineering tasks such as planning code changes, writing code, and verifying results, while coordinating multiple sub-agents to work in parallel. Developers are billed based on usage, with input priced at $1.25 per million tokens and output at $4.25 per million tokens. New users default to the "Contributor" tier upon installation, enjoying lower costs. Meta emphasizes that Muse Code offers significant cost advantages, particularly suited for price-sensitive workflows and application scenarios. Currently available in beta, the tool is already being used internally by some Meta employees, with plans to further expand its adoption.
