I believe this is just a case of OpenAI's naming scheme being weird and confusing. The default model I see on chatgpt.com is GPT 4o-mini, which is not o1-mini.

I believe this is just a case of OpenAI's naming scheme being weird and confusing. The default model I see on chatgpt.com is GPT 4o-mini, which is not o1-mini. OpenAI describes GPT 4o-mini as "Our fast, affordable small model for focused tasks" and o1/o1-mini as "Reasoning models that excel at complex, multi-step tasks".
