Z.ai has made its GLM-5.3 language model available through an OpenAI Chat Completions-compatible API, according to VentureBeat. The posted rate is $1.40 per million input tokens and $4.40 per million output tokens, unchanged from GLM-5.2. Developers on the prior GLM Coding Plan remain limited to that protocol; Z.ai has not set a date or license for open model weights.
