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.…
