Meta opened a developer preview of Muse Spark 1.1 through a paid API on Thursday, making it the company's first paid artificial-intelligence model, with Reuters reporting the preview, The New Stack identifying the shift from model release to billable access and a Reuters syndication report corroborating the debut. [1][2][3]

The paid interface belongs beside the paper's July 8 finding that data-center forecasts accounted for 45 percent of PJM's last three auction costs, because Muse Spark creates a possible source of income against Meta's physical computing costs without showing whether customers will pay enough to offset any meaningful share.

The missing terms matter more than benchmark talk because the available reporting does not specify the API's price, billing unit or contractual limits, identify which weights, tools and deployment routes remain open or free, or supply verified developer uptake and reproducible economics; a preview proves that Meta can charge at the interface, not what demand or revenue will follow.

Reuters and The New Stack emphasize paid access, while the verified X post repeats the Muse Spark debut without proving demand or supporting a claim that Meta abandoned open models; until Meta publishes its price and billing unit, readers cannot compare API income with power, chips or server capacity, although access that once looked only technical can now produce a charge for each use.
