Meta Superintelligence Labs' multimodal, agentic reasoning model — and the first time Meta has charged developers for API access.
Muse Spark 1.1 launches at $1.25 / 1M input and $4.25 / 1M output on the Meta Model API, with $20 in free credits to test before pay-as-you-go pricing kicks in.
Meta introduced Muse Spark 1.1 on July 9, 2026, the latest model from Meta Superintelligence Labs under Alexandr Wang — and a milestone: it's the first time Meta has charged businesses for access to its models. Where Meta's earlier releases leaned on open weights, Muse Spark 1.1 ships a paid tier on the Meta Model API at $1.25 input and $4.25 output per 1M tokens, with $20 in free credits to start.
It's a multimodal reasoning model built for agentic tasks, with major gains in tool and computer use, coding, and multimodal understanding. Meta says it beats Google's latest Gemini release on benchmarks measuring coding and reasoning. The model can actively manage its 1M-token context window rather than treating it as a static buffer.
Muse Spark 1.1 can write and debug code, use software and external tools, understand text, images, and video, and carry out complex multi-step tasks with less human intervention. That agentic profile — plus a low output price — positions it against the mid-tier flagships from OpenAI, Anthropic, and Google, at a time when Meta is accelerating its AI push.
| Model | Input / 1M | Output / 1M | Context |
|---|---|---|---|
| Meta Muse Spark 1.1 | $1.25 | $4.25 | 1M |
| GPT-5.6 Terra | $2.50 | $15 | 1M |
| Claude Sonnet 5 | $3 | $15 | 1M |
| Gemini 3.1 Pro | $2 | $12 | 1M |
| Grok 4.5 | $2 | $6 | 500K |
On price, Muse Spark 1.1 undercuts every mid-tier flagship listed here on output tokens — cheaper than Gemini 3.1 Pro, Claude Sonnet 5, and Grok 4.5 — while claiming benchmark wins over Gemini. It's an aggressive debut for Meta's first paid model.
