- This record represents the GPT-5.4 Pro release whose API page identifies gpt-5.4-pro-2026-03-05 as the fixed snapshot behind the gpt-5.4-pro alias; the API deprecation page carries no retirement entry for this line as of review. ChatGPT, the GPT-5.4, GPT-5.4 Mini, and GPT-5.4 Nano siblings, later GPT releases, fine-tuned derivatives, and the OpenAI API platform itself are separate service, application, or model boundaries.
