GLM 5.3 Model Developed by Z.ai Now Available on Amazon Bedrock

The GLM 5.3 model, developed by Z.ai and notable for its mixture-of-experts architecture with 753 billion parameters, has been made available on Amazon Bedrock, optimized for coding and long-running agent tasks.

Core Features and Capacity of the Model

Developed by Z.ai and published on the Hugging Face Hub, GLM 5.3 stands out as a mixture-of-experts model consisting of 753 billion parameters. This model is specifically optimized for coding processes and long-term agent tasks.

Amazon Bedrock Integration and Managed Infrastructure

The advanced artificial intelligence model is now available to users via fully managed APIs on the Amazon Bedrock platform. This enables developers to benefit from the model without having to manage their own infrastructure.

As part of the access on the platform, various integration features such as cross-region inference, prompt caching, and dedicated service tiers are supported.

Security Capabilities and Performance Enhancement

Serving as a continuation of the GLM 5 series, the new version delivers stronger coding performance. In addition, the model exhibits remarkable capabilities in the field of cybersecurity with successes achieved in tests such as CyberGym.

Cost and Latency Optimizations

To reduce latency and costs in agent workloads, both default automatic prompt caching and explicit cache controls are supported. These features can be actively used in response and chat completion APIs.
