Meta released Muse Code, a terminal coding agent, in beta. Zuckerberg said it handles complete software engineering tasks. The launch comes as Meta faces pressure to monetize AI.
Meta Platforms released a terminal coding agent called Muse Code in beta, the latest addition to its AI tool lineup as the company faces mounting pressure to turn its heavy AI spending into revenue.
“Releasing Muse Code in beta today,” Chief Executive Officer Mark Zuckerberg said in a post on X Wednesday. “It’s a terminal coding agent that takes on complete software engineering tasks across large repos: planning changes, writing code, validating the results. Powered by Muse Spark 1.2, a coding-focused model update.”
In follow-up replies, Zuckerberg said the agent runs specialized background agents that build context over time instead of starting from scratch on each task. It keeps a local event log so that if it crashes mid-task, it resumes where it left off. The tool can be installed with one line, and users can start on a contributor tier at low cost.
Muse Spark 1.2 is an upgraded version of the coding model Meta introduced in April. At the time, Meta said Muse Spark “excels at visual coding,” letting users create websites and mini-games from a single prompt.
The beta launch comes after a June report that Meta was under substantial pressure to prove it can monetize its AI tools, including the Muse Spark model, and provide meaningful growth to justify its massive AI investment. Meta has been spending heavily on computing infrastructure and model development, and analysts have been watching for signs of return on that spending.
Other AI companies are also racing into coding agents. OpenAI announced in June that it plans to expand the capabilities of its Codex agent by acquiring Ona, a provider of secure cloud execution and orchestration technology. OpenAI said Ona’s technology will let Codex users delegate work that may take hours or days to the agent without being tied to a single device or active session.
Google, meanwhile, is in talks with AI coding startup Mechanize to hire some of its talent and sign a non-exclusive licensing agreement for the company’s technology, as reported Wednesday. About a year earlier, in July 2025, Google recruited several top executives and researchers from AI code generation startup Windsurf.
Coding agents represent a fast-growing segment of the AI market, one that could directly affect how software teams allocate time and resources. The AI Board Member: The 20-Minute Fix for a 3-Hour Waste piece earlier this year explored how similar automation tools are reshaping workflows in corporate settings.
Zuckerberg framed Muse Code as an early step. “Muse Spark 1.2 is our next step as we push toward frontier, with larger, more capable models on the way,” he said in another reply. “Install it, use it, tell us what you think.”
