Meta Platforms Inc (NASDAQ:META, XETRA:FB2A, SIX:FB) shares climbed more than 4% on Thursday after the company unveiled an upgraded version of its flagship AI model, which its AI chief says now matches offerings from Anthropic and OpenAI.
The new model, Muse Spark 1.3, marks Meta's "biggest jump so far on model performance," according to Alexandr Wang, the company's AI chief.
Meta said the update improves agentic and coding capabilities and is designed to be easier to use in everyday scenarios.
Developers can already access and pay for Muse Spark 1.3, with availability on Meta's social platforms and Meta AI to follow.
In a blog post, Meta said Muse Spark 1.3 delivers improved performance across agentic and coding tasks, building on lessons learned from months of adoption of Muse Code and the Meta Model API. The company said the model is also easier to use in real-world settings.
"Smarter and more practically useful, Muse Spark 1.3 advances our work toward personal superintelligence," Meta said.
The model is rolling out in Muse Code and the Meta Model API. Previously available reasoning modes are live now, with a max reasoning mode expected shortly once additional safety testing is complete.
Meta said Muse Spark 1.3 is designed to handle open-ended, longer-horizon tasks by pulling context from varied sources, correcting its own plan as it goes, and delivering a final result across a single extended thread.
Meta said its roadmap ahead includes larger models and an open weights release for Muse Spark, among other developments.
