Meta releases Muse Spark Open, an 816-billion-parameter open-weight model for local use
Meta has released Muse Spark Open, a model with 816 billion parameters of which 42 billion are active per token, a one-million-token context and text, image, video and audio input. It ships under a custom license that allows modification and redistribution, with a separate agreement for large model-serving businesses. Running it locally takes hundreds of gigabytes of memory; Meta points to two paired Mac Studio computers. On an independent index the model scores below several Chinese open models.
