### AI overview

Meta released open weights for Muse Spark Open, an 816-billion-parameter model designed for coding and long-running agent work. The report describes its multimodal inputs and million-token context window, tests involving coding tasks and tool use, and license terms for developers and hosted providers. Meta says it scored strongly on an agent tool-use benchmark, while Chinese open models scored higher on the coding benchmark cited.

### Source excerpt

Meta Platforms Inc. today released open weights for its Muse Spark artificial intelligence model, which had been proprietary since its April debut. The release, called Muse Spark Open, is built for coding and long-running agent work. Meta describes it as the most capable open-weight model to come out of a U.S. lab so far. Only [...] The post Meta releases 816B-parameter Muse Spark Open for coding and agent work appeared first on SiliconANGLE.

### AI overview

Meta launched Muse Spark Open, an open-weight multimodal model designed to run locally on Macs. It has 816 billion parameters and a one-million-token context window, and Meta says it is built for complex coding tasks and agentic workflows. Running it locally requires at least 1 terabyte of RAM; Meta also says it is available through several API platforms.
