Philips Hue Picks Open-Weight GLM Models Citing Silent Behavior Drift in Closed LLMs

At IFA, Philips Hue revealed its Custom AI Behaviors assistant runs on open-weight GLM models. Head of technology George Yianni said closed-source models "can change in the background and significantly change behavior," while open-source ones "give control over what runs." Hue pinned a specific model version to prevent automations breaking from upstream API changes. The automation engine executes locally on Hue Bridge Pro.
