Getting 'openai module has no Thread attribute' error when using OpenAI Assistant API

I’m building a chat application with OpenAI’s Assistant API but I keep running into problems when I try to use the Thread class. Every time I attempt to create a new thread with openai.Thread.create, Python throws an AttributeError saying the openai module doesn’t have a Thread attribute.

Here’s my current code:

import openai

openai.api_key = "your_api_key_here"

def chat_handler(message_text, bot_id):
    conversation = openai.Thread.create(assistant=bot_id)["id"]
    
    openai.Message.create(
        thread=conversation,
        role="user",
        content=message_text
    )
    
    execution = openai.Run.create(
        thread=conversation,
        assistant=bot_id
    )
    
    responses = openai.Message.list(thread=conversation)
    return responses["data"][-1]["content"]

if __name__ == "__main__":
    bot_id = "your_assistant_id"
    while True:
        message_text = input("User: ")
        if message_text.lower() in ["quit", "exit"]:
            break
            
        bot_reply = chat_handler(message_text, bot_id)
        print("Bot:", bot_reply)

The error I get is:

Traceback (most recent call last):
  File "chat_app.py", line 28, in <module>
    bot_reply = chat_handler(message_text, bot_id)
  File "chat_app.py", line 6, in chat_handler
    conversation = openai.Thread.create(assistant=bot_id)["id"]
AttributeError: module 'openai' has no attribute 'Thread'

What am I doing wrong here? Is there a different way to work with threads in the OpenAI library?

This is a version issue with the OpenAI library. The Thread class moved - you can’t access it directly from the main openai module anymore. You need to go through the client’s beta interface since Assistants API is still in beta. Create your OpenAI client first, then use client.beta.threads.create() instead of openai.Thread.create(). All the other operations work the same way - they’re all under the beta namespace now. Had this exact problem last month when I was migrating a project. Update to the latest library version and switch from the old direct module calls to the new client pattern.

i think ur using an outdated OpenAI library. try updating it with pip install openai --upgrade. then, switch to the new syntax: client = openai.OpenAI() and use client.beta.threads.create(). the assistant API was moved to beta not long ago.

u r stuck with the old API structre. OpenAI rewrote their library and Thread isnt accessible that way anymore. You need to create the client first, then use the beta endpoints: client = openai.OpenAI() then client.beta.threads.create(). Messages and runs work the same way - they’re all under client.beta now.

Had the same frustrating issue when I started with the Assistant API. You’re mixing old and new OpenAI library syntax. The Thread class isn’t directly accessible from the openai module anymore - they reorganized it under the client structure. You need to create an OpenAI client first, then access threads through the beta interface. Replace openai.Thread.create() with client.beta.threads.create() and update other calls like openai.Message.create() to client.beta.threads.messages.create(). Make sure you’re running the latest openai library version since the API structure changed big time in recent updates. Assistant functionality is still beta so everything goes through that namespace now.
