Key points

  • Coding and agentic workloads are asking more of AI models than ever: refactor a repository spanning hundreds of files, sustain a multi-hour agentic workflow without losing context, and reason through complex systems problems with tool use at every step.
  • GLM 5.3, as published on Hugging Face Hub, is a 753B-parameter mixture-of-experts model optimized for coding and long-horizon agentic tasks.
  • In this post, we show you how to invoke GLM 5.3 on Amazon Bedrock using the OpenAI-compatible APIs and reduce cost and latency with prompt caching.
  • GLM 5 arrived on Amazon Bedrock earlier this year.
