OpenAI retires older ChatGPT models, creating a workflow migration checkpoint
OpenAI announced the retirement of GPT-4o, GPT-4.1, GPT-4.1 mini, and o4-mini from ChatGPT while noting that the API was not affected at that time. Product and API lifecycles are not the same.
OpenAIChecked against OpenAI’s official announcement. This is an archive seed, not today’s live report.

A workflow tied to one model name can change when prompts, formatting behavior, or output quality shifts. Replacement paths should exist before a retirement date arrives.
How this affects your work
Inventory the instructions, custom GPTs, document workflows, and quality baselines your team relies on. Test replacements before the old option disappears.
