- This record represents the GPT-4.1 Mini release whose API page identifies gpt-4.1-mini-2025-04-14 as the fixed snapshot behind the gpt-4.1-mini alias. OpenAI's February 2026 retirement of GPT-4.1 mini from ChatGPT explicitly leaves the API unchanged, and the API deprecation page carries no entry for this snapshot as of review. ChatGPT, the GPT-4.1 and GPT-4.1 nano siblings, later GPT releases, fine-tuned derivatives, and the OpenAI API platform itself are separate service, application, or model boundaries.
Risk statements
The developer publishes no risk-threshold statement for this release. Absence is not evidence of safety.
