glm-5.1 now disables GLM thinking by default via extra_body (LiteLLM strips top-level thinking under drop_params but forwards extra_body verbatim to z.ai). New glm-5.1-reasoning alias = same upstream with thinking enabled, so reasoning is opt-in. Operator call 2026-06-11; primary driver is the pi coding harness. Verified live: glm-5.1 reasoning_tokens=0, glm-5.1-reasoning reasoning_tokens>0.
