zai-glm-4.7 deprecated August 17, 2026, keeps default logprobs shape until then

zai-glm-4.7 is scheduled for deprecation on August 17, 2026 and will keep its existing default logprobs response shape until then. Requests that explicitly set the X-Cerebras-Version-Patch: 2 header still receive the separated reasoning_logprobs field. This affects only the placement of reasoning-token logprobs. See API Versions.
