TMTPOST — Amazon Web Services has made Zhipu AI’s GLM-5.3 large language model available on its Amazon Bedrock platform. The model, developed by Z.ai (Zhipu), is a mixture-of-experts system optimized for coding and long-horizon agentic tasks. It offers a 1-million-token context window and is accessible to eligible enterprise customers through fully managed APIs, including prompt caching and cross-Region inference. Chinese media reports state that AWS will share revenue with Zhipu based on model invocation volume. Official AWS announcements confirm the model’s availability on Bedrock but do not detail commercial terms.
