Meta Opens a Paid Model API With Muse Spark 1.1, Its Turn Toward Metered Access

The Superintelligence Labs model ships a one-million-token context window and agentic tool use, priced at $1.25 per million input tokens and $4.25 per million output tokens.

Meta Opens a Paid Model API With Muse Spark 1.1, Its Turn Toward Metered Access

Meta released Muse Spark 1.1 on July 9. For the first time, it made a first-party model available only through a paid, metered endpoint called the Meta Model application programming interface (API), now in public preview for developers in the United States. The company describes Muse Spark 1.1 as a multimodal reasoning model built for agentic tasks, with a one-million-token context window and improvements in tool use, computer use, coding, and multimodal understanding. It is the second model from Meta Superintelligence Labs and an upgrade of the original Muse Spark that debuted in April.

Pricing is what makes this release significant. Meta lists $1.25 per million input tokens and $4.25 per million output tokens, with $20 in free credits for new sign-ups before pay-as-you-go rates apply. That places the model in direct price competition with the metered APIs from OpenAI, Anthropic, and Google, rather than in the download-and-self-host approach Meta established with Llama.

The capability claims come from a vendor launch, and independent reproductions of the tool-use, coding, and long-context benchmarks are not yet available. What is verified is the commercial structure. There are no downloadable weights, there is a published rate card, and the preview is limited to one region.

Veracity: Corroborated

88/100

If true, who benefits: Closed-API incumbents gain a well-capitalized price rival, and Meta shifts revenue toward inference billing, while the framing pressures anyone standardized on downloadable Llama weights.
The nuance: The commercial structure (paid US-only endpoint, $1.25 and $4.25 per million tokens) is independently confirmed, but the "retreat from open weights" is a narrative Meta has not stated, and every capability benchmark remains vendor-supplied and unreproduced.

An open-source-intelligence read of how likely this story is true with its real nuance, not a judgment of any outlet. It assesses the claim, weighing independent and adversarial reporting. How we label confidence.

What this means

The mechanism here is monetization, not capability. Meta built its standing by distributing Llama weights for download. A metered model with no downloadable weights shifts revenue toward inference billing and away from the open-weight ecosystem it helped create. Closed-API incumbents gain a well-capitalized price competitor. Teams that standardized on downloadable Llama models would lose their largest Western supplier of that tier if Meta routes its best models to the API only.

What to watch

Whether Meta continues to ship downloadable weights for its strongest models alongside the API, which would signal a dual strategy rather than a full retreat from open weights.
Independent benchmark reproductions of Muse Spark 1.1 against GPT, Claude, and Gemini, because the agentic and coding claims are so far vendor-stated.

Observations to monitor, not financial advice.

US Labs Close Weights to Monetize

Western frontier labs increasingly retreat from open weights toward closed, metered APIs to capture revenue, ceding the downloadable open-weight tier to Chinese suppliers and splitting the market by license as much as by capability.
