Meta has released Muse Spark 1.2, marking its third model release in just four months. The model scores 54 on the Artificial Analysis Intelligence Index, showing significant improvements in agentic knowledge work capabilities.

This performance places Meta in a tie for third place among US labs alongside xAI, narrowly trailing current frontier models like Claude Opus 5, GPT-5.6 Sol, and Kimi K3. Observers note that Meta has successfully leapfrogged competitors in model quality and is maintaining an impressive shipping velocity, with the even more capable Watermelon family still on the horizon.
