Assistants are being deprecated by OpenAI
End of life is planned for mid-2026. We recommend using OpenAI models directly with the appropriate tools instead. For knowledge bases, you can use a Vector Store directly, which provides the same capabilities as Assistants (and often better performance). AI Engine is focusing development efforts on the Responses API going forward.

First, you will need to access the AI Engine dashboard and, under the “Server Modules” tab, enable the Assistants feature.

This action will generate a new section in the settings where you can view all of your OpenAI assistants. This is a read-only section, you wont be able to modify or add assistants from there, everything will be done on the OpenAI side.

To create them, head to the OpenAI Assistants dashboard.

Once you’ve created one or have some assistants ready, return to the AI Engine Assistants section and click the refresh button in the top right corner. You should see it/them appear in the table.

There’s no need to return to this tab anymore. Now that the assistant is available, let’s proceed to use it!

If you don’t see your assistants after refreshing the list, make sure that your server can communicate with OpenAI and that your WordPress REST API is operational and you have the right permalinks configured.

For this, navigate to the chatbot tab where you operate your regular chatbots for AI Engine. Select or create a new chatbot, and in the Main Setting section, you will be able to change the chatbot mode to assistant.

And it’s done! You are now using your OpenAI assistant directly within AI Engine. Have fun! 😊

When using an Assistant this enables your users to send files directly through your chatbot, to learn more please read this documentation.

Organizations’ assistants

You can connect to your OpenAI account and go to the API Keys section to select your default organization. If it’s already the case, switch to personal, confirm the dialog box, and switch back to your organization to reset. Then, you’ll need to create a new API Key so that the header matches. Once this is done, you can refresh the assistant in AI Engine, and you should see it appear! 😊
