The Assistants API cannot access files for some reason

For some reason, every time I attach a file_id to a message, the assistant cannot retrieve it. The purpose of the file is for retrieval. I would always get a message along the lines of this:

I’m sorry, but as an AI, I do not have the capability to download or view files. However, you can tell me about the contents of the document or ask questions, and I will do my best to provide relevant and accurate information based on the data and knowledge I have been trained on up until April 2023.

And some other variations of this message.

Here’s a sample code:

thread = client.beta.threads.create()

message = client.beta.threads.messages.create(,
    content="Tell me about this document.",

run = client.beta.threads.runs.create(, assistant_id="asst_xxx"

while True:
    retrieve_run = client.beta.threads.runs.retrieve(,

    if retrieve_run.status == "completed":

messages = client.beta.threads.messages.list(

Has anyone encountered the same issue? I would like to know how you solved it. Thanks!

I had the same issue earlier today - and then a few hours later it worked again as expected. I suspect this is just the consequence of work being done behind the curtains on the API.

Tried it out again, and somehow it now works. Previously it would fail 100% of the time.

Whenever I mention the word “document” in my prompt, it seems to be able to find the file. However if I don’t mention the word “document”, it’s kind of a hit or miss.

Also, sometimes when it does detect the file, it will mention things like:

I’m unable to access the entire document, but based on the sections I was able to review, it appears to be related to…

or something like

The file seems to be an … However, the text appears to be corrupted or garbled, making it difficult to comprehend.

Would you mind telling me the instructions that you gave to the assistant?

Yeah I’m seeing this exact language for many of my requests as well. Has anyone found a solution here or gotten the attention of the OAI team?

Still experiencing this for PDFs on December 11th with both GPT-4 preview and 3.5-turbo.

I am using the following code with gpt-4-turbo-preview, which is copied directly from the OpenAI documentation:

thread = client.beta.threads.create(
                    "role": "user",
                    "content": "my prompt"
                    "file_ids": [],

Every time I run it, I get some version of this message:
I’m sorry, but I can’t directly access or analyze the content of files uploaded. However, if you could provide some details or excerpts from the documents, I would be happy to help analyze those based on the instructions you’ve provided.

I read from others in this chain that it may be an intermittent problem. However, it has not worked for me no matter how many times I run it over the past few days.

I am assuming the problem is on OpenAI’s end and not with the code. If on their end, has anyone come up with a workaround?

FIX: Rookie Mistake. I misunderstood the documentation. I thought that, because I was not storing the docs with the Assistant, that I did not need to turn “Retrieval” on for the assistant. Once I did that, everything worked fine.
