OpenRouter's catalog gives seven OpenAI models, GPT-5 and o3 among them, an expiration date of December 11

OpenRouter's model catalog now shows an expiration date of December 11, 2026 for seven OpenAI models: GPT-5, GPT-5 Mini, GPT-5 Nano, GPT-5 Pro and GPT-5 Image (each with a 400,000-token context, listed between August and October 2025), and o3 and o3 Pro (200,000 tokens, listed in April and June 2025). None of the entries had an expiration date before. This is a catalog field only; the entries do not say why or what happens to the models after that date.
