Once you're happy with your GPT, you can go ahead and generate an assistant from it. To do this you will need to go to the edit GPT screen and then select the Configure option.

1) In another tab, open the OpenAI API page, and go to the Assistant's tab. Click on the button to create new assistant or open the assistant you would like to mirror the GPT onto.

2) Find your GPT instruction and files by going to GPT explore page then selecting Edit on your desired GPT. Next, toggle the Configure option. Paste the instruction into the Assitant's instruction field in the API page.

3) Download all the uploaded documents from the GPT configure page, then go to the Assitant detail page and upload the documents there.

4) Make sure the settings for GPT capabilities are mirrored exactly in the Assistant's settings.

5) Save the Assistant, wait until it updates and you'll have an Assistant that's generally as close to your GPT as you can get. You should continue to use the GPT builder to evolve your GPT. Just remember to update the instructions in the Assistant page to keep it up to date!

Add the Assistant to your website
