Glm

Learn how to integrate a cheaper $18 AI model (Z.ai GLM) as a worker agent within Claude Code and Codex to save costs. Discover the optimal workflow for delegating well-defined tasks while keeping your existing setup, tools, and context intact.

Z.ai's GLM-5.3 keeps the same 743B base model as GLM-5.2 but extracts massive gains through post-training scaling alone. Terminal-Bench 3.0 jumps 514%, and unexpected cyber capabilities have already found 2,436 real-world vulnerabilities.
