- This record represents the GPT-5 Nano release whose API page identifies gpt-5-nano-2025-08-07 as the fixed snapshot behind the gpt-5-nano alias; OpenAI's deprecation page lists that snapshot for shutdown on 2026-12-11 with gpt-5.6-luna as the recommended replacement. ChatGPT, the GPT-5, GPT-5 Mini, and later GPT-5.x releases, fine-tuned derivatives, and the OpenAI API platform itself are separate service, application, or model boundaries.
