The model shipped in April. The interface developers need to build on it has slipped repeatedly, with no firm date until Meta said this week it would arrive this month.
A model without an API is a demo, not a platform. That is the awkward position Meta’s Muse Spark has occupied since April, when the company launched the model but held back the application programming interface that outside developers need to build on it. According to the Wall Street Journal, Meta has pushed that release back repeatedly and, as of Tuesday, had no scheduled launch date.
The gap has now stretched close to two months. Meta’s AI chief told developers to expect the API “soon” after the April launch, the Journal reported, citing people familiar with the matter, and soon has kept receding. For developers who have built product plans around Muse Spark, an indefinite delay on the interface is the part that actually bites; the model exists, but the means of using it at scale does not.
Meta’s account is more upbeat. A company spokesperson told Reuters on Wednesday that Meta is already testing the API with some early partners and expects to release it this month. The two versions are not flatly contradictory. A limited private test running while a public launch date stays unset is exactly the situation the Journal described, read from the optimistic end.
