According to Latent Space's AINews briefing, Meta's Muse Spark 1.3 has reached parity with GPT-5.6-Sol. The newsletter frames the result as confirmation that Meta Superintelligence now belongs in the top tier of frontier AI labs.

The more striking detail is the reported economics: training the model came at a discount of more than 90 percent. If accurate, that suggests Meta matched a leading model while spending far less on compute, a significant shift from the usual assumption that frontier training requires enormous budgets.

Latent Space describes the development as a comeback story for Meta, which has often been seen as trailing in the race for frontier AI. The report is based on the newsletter's own coverage and has not been independently verified.
