Meta Launches First AI Coding Agent Muse Code; Shares Drop on Weak Revenue Outlook
Meta launched Muse Code on Wednesday, its first AI coding agent built on the Muse Spark programming model, competing with Anthropic and OpenAI. The agent installs with a single command and handles full software engineering tasks, including planning, coding, and verification, and is now in beta. It uses a multi-agent architecture that spawns sub-agents to work in parallel on isolated work trees for large codebases. Chief Executive Mark Zuckerberg said an internal test built six independent game features simultaneously without conflicts. The launch follows last week's earnings report showing weak revenue guidance and a decline in second-quarter free cash flow, which dragged down the share price.
Meta officially launched Muse Code, its first AI coding agent, on Wednesday. The product, built on the previously released Muse Spark programming model, competes with comparable offerings from Anthropic and OpenAI. According to Meta AI head Alexandr Wang, users can complete installation with a single command, after which the agent can handle complete software engineering tasks, covering application scenarios such as planning code changes, writing code, and verifying output. Muse Code is now in beta testing.
In terms of architecture, Muse Code employs a multi-agent coordination mechanism for large software codebases. When faced with large tasks, the system automatically spawns multiple sub-agents that work in parallel in isolated work trees without interfering with one another or requiring modifications to the local working copy. Meta Chief Executive Mark Zuckerberg revealed that in internal testing, Muse Code built six independent features simultaneously in a game project without producing any conflicts.
Meta continues to increase investment in AI research and computing infrastructure. The company released its earnings report last week, showing weak revenue guidance and a decline in second-quarter free cash flow, which pushed its share price lower.
