Oct 15 : Meta Platforms on Thursday released an open-weight version of its Muse Spark artificial intelligence model for coding and AI agents, expanding developers’ ability to download and adapt the technology.
Open-weight models make trained parameters available for developers to modify, unlike proprietary models that remain under their creators’ control. They can offer businesses a lower-cost alternative to closed systems.
• Meta said Muse Spark has 816 billion total parameters, with 42 billion active at a time, and can handle a context window of up to 1 million tokens
• The model can run locally on two Apple M5 Ultra Mac Studio computers and is also available through some API providers
• CEO Mark Zuckerberg has argued that advanced AI should not be concentrated among a small number of companies
• While open-weight models can give companies greater control over their data, they can require significant computing resources and technical expertise to operate at scale
• In August, Meta had released Muse Glimmer, a smaller open-weight model
