Custom gpt vs assistant api

I completely agree. I originally built my GPT, and it is working exactly how I want, giving exactly the right answers based on the supporting documents and data provided. I have then built an Assistant using GPT-4-1106 Preview, and I’m getting ok answers, but it’s nowhere near the level that my GPT is giving me.

I copied the instructions from the GPT to the Asistant to make them both as close as possible but still not getting the same level of response. It’s almost like GPTs are using GPT5 and Assistants are using GPT-4-1106 Preview as mentioned.

If only OpenAi would let us port a GPT to Assistant so we can make it available outside of the openai website. or enable API access to the GPT and have the pricing model be metered.
