Zuck's Muse to Spark joy with open weights release 'soon'

Meta will release an open weights version of its flagship AI model Muse Spark "soon," CEO Mark Zuckerberg promised in an X post on Wednesday. In the meantime, Muse Spark 1.3 — the smarter, less yappy, and more efficient version of the model — is now live on the Facebook parent's API service and Muse Code CLI. Since releasing Muse Spark in April, Meta has released several refinements in order to keep pressure on the competition and convince investors its rampant capex isn't for naught.
