ChatGPT web app update includes references to new models like 'GPT-4.1', 'GPT-4.1-mini', 'GPT-5 Thinking Mini', 'GPT-5-mini', 'GPT-5.2', 'GPT-5.3', and several 'gpt-5' and 'gpt-4o' variations, alongside numerous internal feature flags and internal API endpoints.

READY TO POST:

looks like openai is testing a bunch of new gpt models internally! saw gpt-4.1, gpt-5 mini, and even a 'gpt-5 thinking mini' in the latest chatgpt web app deploy.

major gpt model updates possibly coming soon? new strings in the chatgpt frontend hint at gpt-4.1, gpt-5 variants, and lots of internal-only features. could be a big one.
