README

GLM-5.3-Flash is Z.AI's faster, lower-cost model with a 1M-token context window and up to 128K output tokens, built for coding, agentic, and multimodal workloads.
  • GLM-5.3-Flash is Z.AI's faster, lower-cost model, suited to coding, agentic, and multimodal workloads.
  • Served through the Claude Messages API (POST /v1/messages), the same low-friction path as GLM-5.3.
  • Cached input pricing reduces cost for repeated prompts, templates, and policy-heavy workloads.
