June 3 (Reuters) – Meta has repeatedly pushed back plans to release its new Muse Spark AI model ​API to developers, and as ‌of Tuesday, had no scheduled launch date, the Wall Street Journal reported, citing people familiar with the matter.

A Meta spokesperson told Reuters ‌on ​Wednesday that the ⁠company is already testing ⁠the Application Programming Interface (API) with some early partners and is looking forward to releasing it this month.

An API ​is a type of software interface that determines how two software ⁠systems will interact.

“The muse ⁠spark API will be coming ​soon,” Meta AI Chief Alexandr Wang announced ​in a post on X in ‌April.

Meta unveiled Muse Spark in April as the first model built to close the gap with rivals. Muse ⁠Spark is the first in a new series of models created by the company’s Superintelligence ⁠Labs.

Earlier ‌on Wednesday, Meta unveiled an ⁠AI agent aimed at helping ​businesses ‌carry out day-to-day operations, hinting ​at the ⁠company’s ambitions to compete with rivals such as OpenAI, Anthropic and Alphabet’s Google.
