This was mentioned in OpenAI's report. People rated o1 as the same or worse than GPT-4o if the prompt didn't require reasoning, like on personal writing tasks.
Given the rate limits are 30 reqs/week most probably want to start with:
- Try it a bit with 4o, see if you're getting anywhere
- Switch to the new o1 model if it's just not working out, take your improved base prompt and follow ups with you so it only counts as 1 req
- If your request requires reasoning, switch to o1 model.
- If not, switch to 4o model.
This applies to both across chat sessions and within the same session (yes, we can switch between models within the same session and it looks like down the road OpenAI is gonna support automatic model switching). Based on my experience, this will actually improve the perceived response quality -- o1 and 4o are rather complementary to each other rather than replacement.
