Aug. 10 (UPI) -- Meta announced on Monday that its most powerful AI model will be open source, challenging models by OpenAI and Anthropic.

Meta CEO Mark Zuckerberg made the announcement in a post on Instagram and a blog post, saying the company's newest AI model Muse Spark 1.2 can now be used by all. He also announced the incoming launch of Muse Glimmer, a new family of open source models that are laptop friendly.

"Foreign labs currently hold several advantages here since American labs have to comply with many additional restrictions on training data," Zuckerberg wrote in a blog post on Meta.com. "[U.S.] policy must reduce this additional friction if we want American open source models to lead over time."

Zuckerberg added that he does not believe restricting access to foreign AI models is "an effective solution."
