Meta releases open-weight Muse Spark model for coding, agentic tasks

Oct 15 (Reuters) - 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
