Details
Meta's Muse Spark Open is now available on AI Gateway, offering an open-weight reasoning model designed for coding and agentic workflows. The model handles tasks such as multi-file refactoring, debugging, and understanding large codebases, supporting both text and image input within a 1M-token context window.
Integration and Usage
Developers can access the model using the identifier meta/muse-spark-open across various API formats, including the AI SDK, OpenAI-compatible Chat Completions and Responses APIs, and the Anthropic-compatible Messages API. It integrates with coding agents like Claude Code, Codex, and Cursor by installing the latest Vercel CLI and running the setup command.
Platform Features
Accessing the model through AI Gateway includes Zero Data Retention (ZDR) and ensures no training on user data, without requiring separate provider accounts. The gateway provides a unified API for tracking usage and cost, configuring retries, and optimizing performance, while reflecting provider pricing with no markup or platform fees on inference.
