Muse Spark Open 於 AI Gateway 正式上線

Muse Spark Open from Meta is now available on AI Gateway. The open-weight reasoning model is designed for coding and agentic workflows, including multi-file refactoring, debugging, and understanding large codebases.

Muse Spark Open supports text and image input with a 1M-token context window, allowing agents to work with code and screenshots in the same request. It is available with ZDR and no training, without creating separate provider accounts.

Use meta/muse-spark-open as the model name across all API formats and coding agents. The model is available across the AI SDK, the OpenAI-compatible Chat Completions and Responses APIs, the Anthropic-compatible Messages API, and coding agents connected to AI Gateway.

To use it in Claude Code, Codex, Cursor, and more, install the latest Vercel CLI and run setup:

Then select meta/muse-spark-open in the agent. See the coding agents guide for details.

Try Muse Spark Open in the model playground.
