What changed
Source summary
Amazon Bedrock added general availability of Z.ai's GLM 5.3 model for agentic coding and long-running software engineering tasks. It is a mixture-of-experts model with 753B total parameters (about 40B active per token), the same base model as GLM 5.2 with gains from scaled post-training, offering a 1-million-token context window and up to 128K output tokens. Reasoning is always on with a selectable effort level to balance latency and token use against quality, and Bedrock adds explicit prompt caching to reduce latency and input costs on reused context. Access is limited to eligible enterprise customers via US and Global cross-Region inference profiles.
