Meta's Muse Spark Open narrows the gap with Chinese open models, but its license may hold it back
AINathan Lambert says Meta's Muse Spark Open is now the strongest American-made open-weight model, with 816B total and 42B active parameters and a 1M-token context window. He argues its custom license, which includes a revenue gate above $20M per month and an acceptable use policy, makes it far less open than standard open-source licenses and could weaken adoption.
