Muse Spark 1.1 from Meta is now available on AI Gateway.

It is a multimodal reasoning model with a 1M token context window built for agentic tasks, accepting text, image, video, PDF, and audio inputs.

Muse Spark 1.1 plans and orchestrates work across tools and services, operating as a main agent or as a subagent, and it works with new tools, MCP servers, and custom skills without examples. The model supports parallel tool calling, structured output, and built-in search with citations.

To use Muse Spark 1.1, set model to meta/muse-spark-1.1 in the AI SDK:

import { streamText } from 'ai';

const result = streamText({

model: 'meta/muse-spark-1.1',

prompt: 'Read this product spec PDF and implement the API it describes.',

});

AI Gateway provides a unified API for calling models, tracking usage and cost, and configuring retries, failover, and performance optimizations for higher-than-provider uptime. It includes built-in custom reporting, Zero Data Retention support, budgets for API keys, routing rules, and more.

AI Gateway reflects provider pricing with no markup and does not charge a platform fee on inference, including on Bring Your Own Key (BYOK) requests.
