GLM vs Qwen tool calling differences force separate handlers in Codex proxy
TheZachMueller · x · 2026-10-05
TheZachMueller shares a detail from his Codex third-party model setup: GLM and Qwen each want tool use called slightly differently, so he needed separate handlers for the two models in his proxy. A concrete illustration of why compatibility layers are unavoidable when mixing open models in agent tooling, and how far agent protocols remain from standardization.
