The model is also available via the Meta Model API with expanded global access, following the July release of Muse Spark 1.1.", "body_md": "Meta is entering the AI coding-agent race with Muse Code, a new terminal-based tool now available in beta for macOS and Linux.\n\n## Muse Code arrives alongside Meta’s new Muse Spark 1.2 model\n\nPowered by the new Muse Spark 1.2 model, it is designed to handle complex software engineering work across large repositories.\n\nFor Mac users, Muse Code installation is [a one-line command](https://research.meta.ai/blog/introducing-muse-code-and-muse-spark-1-2):\n\n```\ncurl -fsSL https://dev.meta.ai/install.sh | bash\n```\n\nUnlike ChatGPT Codex and Claude Code, there’s currently no dedicated app interface for Muse Code.\n\nMeta says Muse Code can plan changes, write code, validate its work, and coordinate persistent background agents that remain active throughout a session.\n\nIts local event log records model calls, tool use, approvals, and edits, allowing work to resume after a crash. Built-in commands can also generate a plan, stress-test it, or continue working toward a specified goal.\n\nMuse Spark 1.2 is described as a coding-focused update with gains in code generation, debugging, codebase understanding, and long-running developer workflows.\n\nThe model is available through both Muse Code and the Meta Model API with expanded global access.\n\nThe release follows Meta’s July launch of Muse Spark 1.1, which upgraded the model’s agentic and multimodal abilities and introduced Meta’s paid API service for developers.\n\nBefore that, Meta [replaced Llama with the original Muse Spark](https://9to5mac.com/2026/04/08/goodbye-llama-meta-unveils-muse-spark-ai-with-new-contemplating-mode/) in April, then used it to [expand the Meta AI app](https://9to5mac.com/2026/05/12/meta-ai-app-enhanced-with-new-features-using-muse-spark-heres-whats-new/) and power [new image-generation features](https://9to5mac.com/2026/07/07/meta-ai-app-adds-image-generation-also-powering-whatsapp-and-instagram-features/) across Meta’s apps.\n\n**Do more with your Apple products**\n\n[Apple AirTag 2 | Add Find My tracking to keys, bags, bikes, more](https://amzn.to/4vjNWN1)\n\n[AirPods 4 | Apple’s newest wireless headphones](https://amzn.to/43ndewV)\n\n[AirPods Pro 3 | Apple’s best wireless headphones](https://amzn.to/4ut3FYp)\n\n[Beats USB-A to USB-C Cable | The official CarPlay cable](https://amzn.to/4mpKs7K)\n\n*FTC: We use income earning auto affiliate links.* [More.](https://9to5mac.com/about/#affiliate)\n\n[our homepage](http://9to5mac.com/)for all the latest news, and follow 9to5Mac on\n\n[exclusive stories](https://9to5mac.com/feature/exclusive/),\n\n[reviews](https://9to5mac.com/guides/review/),\n\n[how-tos](https://9to5mac.com/guides/how-to/), and\n\n[subscribe to our YouTube channel](https://www.youtube.com/9to5mac)", "url": "https://wpnews.pro/news/meta-launches-muse-code-ai-coding-agent-for-macos-and-linux", "canonical_source": "https://9to5mac.com/2026/08/05/meta-launches-muse-code-ai-coding-agent-for-macos-and-linux/", "published_at": "2026-08-05 19:25:19+00:00", "updated_at": "2026-08-05 19:50:47.465894+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-products", "ai-tools", "generative-ai"], "entities": ["Meta", "Muse Code", "Muse Spark 1.2", "Muse Spark 1.1", "Meta Model API", "ChatGPT Codex", "Claude Code"], "alternates": {"html": "https://wpnews.pro/news/meta-launches-muse-code-ai-coding-agent-for-macos-and-linux", "markdown": "https://wpnews.pro/news/meta-launches-muse-code-ai-coding-agent-for-macos-and-linux.md", "text": "https://wpnews.pro/news/meta-launches-muse-code-ai-coding-agent-for-macos-and-linux.txt", "jsonld": "https://wpnews.pro/news/meta-launches-muse-code-ai-coding-agent-for-macos-and-linux.jsonld"}}
