Meta Launches Muse Spark 1.1, Its First Paid API Model, Priced Below Sonnet
Meta opened a developer API for Muse Spark 1.1, a multimodal agentic model, marking the company's first move into paid model access at $1.25/$4.25 per million tokens.
Meta has opened a public preview of a developer API for Muse Spark 1.1, its first model ever offered as a paid product rather than free through its own apps. The launch pushes Meta directly into the agentic coding market where Anthropic and OpenAI have set the pace.
- Pricing: $1.25 per million input tokens, $4.25 per million output tokens, plus $20 in free credits for new accounts
- Context window: 1 million tokens
- API compatible with both the OpenAI SDK and the Anthropic Messages format, base URL api.meta.ai/v1
- US-only at launch; model name muse-spark-1.1
- On Meta's own benchmarks it leads on tool and computer use but trails Opus 4.8 and GPT-5.5 on pure coding tasks
The price sits above OpenAI's entry-level mini tier and Anthropic's Haiku 4.5, but undercuts Sonnet-class pricing, another sign of the token price war that has already pulled in xAI's Grok 4.5 this week. Compare it yourself in the coding arena.
