Developers Are Still Waiting for Access to Meta's Latest AI Model

In the race to release AI models and ways for developers to use them, Meta appears to be lagging behind.

The Wall Street Journal reported Wednesday that, according to those familiar with Meta's plans, there's no firm release date for an API, which stands for application programming interface, for Muse Spark, an advanced AI large-language model the company released in April. At the time, the company said a release of the API, which allows developers to use the closed-source, proprietary model, was coming soon. That still hasn't happened two months later.

A Meta spokesperson said in an email to CNET that the API should be available in June.

"We know people want the API, and we're excited to get it into their hands," the representative said in the email. "We're already testing with some early partners and look forward to releasing it this month."

The spokesperson also pointed to an April 10 X post where Meta's chief AI officer, Alexandr Wang, said, "the muse spark API will be coming soon!"
