Meta has launched Muse Code, its first proprietary AI coding agent, to compete with Anthropic and OpenAI. Led by Alexandr Wang, the tool performs end-to-end software engineering tasks (planning, coding, verification) in a single interface and is available in preview. Pricing starts at $1.25/$4.25 per million tokens for input/output, with a 10x discounted tier for data-sharing agreements and enterprise no-log options. This reflects Meta's strategy to monetize AI infrastructure investments and compete on cost.
