Is GPT4-o dumber in Assistans API than in normal chat?

[tobson]

Hello,

I am asking myself if the new gtp4-o model ist working differently via assistants API than via the casual chat in the browser?

I would like to use the vision capabilities to transcribe handwritten notes. If I put a photo of my handwritten notes into ChatGPT gpt-4o it perfectly transcribes my ugly written notes. But if I am creating an assistant in the playground (of course using the gpt-4o model too) it gets a lot of things wrong and starts to hallucinate.

I tried it a bunch of times and the result is always the same: Via the normal chat it works perfectly, in assistants API it works badly.

How can that be? Isn’t it the same model, so the results should be the same?

Thanks!

Got the same behavior in the same tasks.

GPT-4 omni text recognition via API works worse than on chatgpt_com

Hello all! I’m investigation poor text recognition via API with GPT-4 Omni. The original OpenAI chat on chatgpt_com is working like a charm, text is 100% equal to PNG, no fictional words or sentences. If I us API call to GPT-4o for a one page text I always get only the first paragraph almost correct, the others are fictional. I tried custom prompts to stop using Tesseract and use internal vision capabilities. But no luck. What should I do? [proof]

Will you find the reason or a workaround?

Same here, the performance of vision in assistant is significantly worse compared to classic gpt4o.

Same, with just a regular text, any solutions?
