Meta's Muse Double Play: Open 816B Model, Closed Frontier Bet
Meta released Muse Spark Open, an 816-billion-parameter open-weight AI model built for coding and agentic work, alongside its closed frontier models Muse Wonder and Muse Wonder Full. Researcher Nathan Lambert calls Spark Open the strongest American-made open model by a wide margin, saying it cuts the US-China open-model gap roughly in half.
