Muse Spark Open framed as Meta's open-weight gambit in the US-China AI race
An analysis argues that Meta's release of Muse Spark Open, its 816B open-weight model for coding and long-horizon agent work, is an attempt to regain ground in the open-weight race as China gains strength in the field. The contest is shifting from which lab builds the most powerful proprietary model to whose open-weight model becomes the default developers build on. Meta positions it as the most capable open-weight model to come out of the US.
