Meta returns to open weights, Brex innovates agent security, SwitchBot adds smart home AI

Meta has re-entered the open-weights LLM space with the release of Muse Glimmer, a 30B parameter model, marking their first open-weights release in over a year. In a contrasting approach to agent security, Brex has developed CrabTrap, an open-source HTTP proxy designed to monitor network traffic rather than policing agent code directly. Additionally, SwitchBot has integrated an LLM assistant named Kata into its smart home app, offering voice control for home devices, albeit with a daily processing limit. Meanwhile, Anthropic has described its approach to watermarking AI-generated text, though details on detection remain scarce. AI

IMPACT Meta's open-weights release could spur further development in the open-source LLM community, while Brex's agent security approach offers a novel perspective on managing AI risks in production environments.
