Meta has recently announced that it plans to focus its main attention on developing large language models with "open weights". As a first step, the company has released a new model called Muse Glimmer and promised to make its more powerful model, Muse Spark 1.2, available as open-source to developers in the coming weeks.
Alongside this news, Mark Zuckerberg, the CEO of Meta, outlined his company's new philosophy regarding AI governance in a detailed article. In this piece, he sought to distinguish Meta from competitors like OpenAI and Anthropic, which use proprietary and closed models. Zuckerberg believes that the open-source approach not only benefits the developer community, but also serves as a response to rival companies' efforts to monopolize the AI market through lobbying governments.
