## Human Summary
AWS has launched Z.ai's GLM 5.3 on Amazon Bedrock, featuring a 753B MoE architecture designed for coding and agentic workflows.

## Agent Summary
GLM 5.3 is now on Amazon Bedrock. It is a 753B-parameter MoE model accessible via OpenAI-compatible APIs, supporting prompt caching and integration with open-source agents like Strix.

## Body
Amazon Web Services has announced the availability of Z.ai's GLM 5.3 on Amazon Bedrock. The model uses a 753B-parameter mixture-of-experts (MoE) architecture targeted at coding and long-horizon agentic tasks. It supports invocation via OpenAI-compatible APIs, incorporates prompt caching to reduce latency and costs, and can be used in agentic security testing workflows such as the open-source Strix agent.

## Recommended actions
- Test invoking GLM 5.3 on Amazon Bedrock using OpenAI-compatible APIs.
- Evaluate prompt caching configuration for cost and latency optimizations.
- Assess GLM 5.3 with open-source tools like the Strix agent for authorized security workflows.
