OpenRouter's catalog drops the December 31 expiration date for Z.ai: GLM 4.5V

OpenRouter's model catalog no longer shows an expiration date for "Z.ai: GLM 4.5V" (z-ai/glm-4.5v). The entry had listed December 31, 2026 since October 24. The model, listed since August 11, 2025 with a 65,536-token context, remains in the catalog. This is a catalog field; neither OpenRouter nor Z.ai has given a reason for adding or removing the date.
