The model `gpt-5` does not exist or you do not have access to it.\

I can’t access gpt-5 and other v5 models through the API. I first got a message saying I need to verify my org, which I did. But now I’m getting a new error message:

> curl --request POST   --url https://api.openai.com/v1/responses   --header "Authorization: Bearer $OPENAI_API_KEY"   --header 'Content-type: application/json'   --data '{
        "model": "gpt-5",
        "input": "How much gold would it take to coat the Statue of Liberty in a 1mm layer?"
}'
{
  "error": {
    "message": "The model `gpt-5` does not exist or you do not have access to it.",
    "type": "invalid_request_error",
    "param": null,
    "code": "model_not_found"
  }
}

It’s already been like 15 minutes after verifying that I still can’t access these.

GPT-5 Rollout

We are gradually rolling out GPT-5 to ensure stability during launch. Some users may not yet see GPT-5 in their account as we increase availability in stages.

I’d see it here:

I’ve been verified for many months but get the same errors. It must not be rolled out yet.

We haven’t started roll-out yet! I will post in Announcements when available, and an email blast will go out as well.

openai has done it again, you guys outperformed the world. congratulations to everyone involved. just tested it on a couple of things via the api. i guess those 80-120h a week really did pay off. best of luck on the launch, i see you all on the other side, godspeed.

I had GPT-5 - started testing, then it disappeared & I am back with the previous options of GPT-4o and variants.

I had only run about ten prompts when it vanished.

Did OpenAI hit a pothole?

You’re not alone – same thing happened to me.
I was already deep into testing GPT‑5 (and starting to get really excited), and suddenly – poof – gone without a trace.
Back to GPT‑4o like nothing ever happened.
It’s like the AI gods gave us a taste… then hit the undo button.
Here’s hoping this was just a temporary rollback or a phased rollout misfire. Fingers crossed!

Here in Scotland. Gpt5 coming up in the YouTube feed; nothing in the app or web versions coming up ! Wondering if it’s because I used up all my agent messages for the month?

11

Same here, good to know I was not hallucinating :smiley:

I am also getting this error with my batch GPT-5:

The model `gpt-5-2025-08-07-batch` does not exist or you do not have access to it.

I am using gpt-5-2025-08-07 in my batch file, but it appears it is getting updated to gpt-5-2025-08-07-batch when it is run.

I ran a batch file on the 8th which had a number of failed rows. I have been trying to re-run those errored rows, but I keep getting that same error.

i am suddently started getting same error today, it worked for serval days but now. i ran a simple batch using

{“custom_id”:“t1”,“method”:“POST”,“url”:“/v1/responses”,“body”:{“model”:“gpt-5”,“input”:“Say hello #1”}}
{“custom_id”:“t2”,“method”:“POST”,“url”:“/v1/responses”,“body”:{“model”:“gpt-5”,“input”:“Say hello #2”}}
{“custom_id”:“t3”,“method”:“POST”,“url”:“/v1/responses”,“body”:{“model”:“gpt-5”,“input”:“Say hello #3”}}

and got response
“response”: {“status_code”: 404, “request_id”: “XXXX”, “body”: {“error”: {“message”: “The model gpt-5-2025-08-07-batch does not exist or you do not have access to it.”, “type”: “invalid_request_error”, “param”: null, “code”: null}}}

It seems to be working today. Does it work for everyone again, and does anyone know if the issue might happen again?

15

This is resolved and verified OK now, OpenAI identified the issue and implemented a fix as of twelve hours ago.

Is GPT-5 globally available to all API developers or just selectively available? We verified our organization yesterday but still got this message today:

”No. I’m not GPT-5. I’m a GPT-4–class OpenAI model (ChatGPT). If you’re looking for specific capabilities, tell me what you need and I’ll let you know what I can do.”

Anybody else having the same issue - not having access to GPT-5 API?

18

If your API request is not failing with "model":"gpt-5", then you are getting gpt-5. The model snapshot name will be returned in the response object.

If you want to ask what the AI is, you have to tell the AI what it is. That is what the developer message role is for.

There is an application-breaking system message injection by OpenAI on GPT-5, saying, “- You are ChatGPT, a large language model trained by OpenAI…You are an AI assistant accessed via an API.” Don’t make them add even more uselessness there with “why doesn’t it know?”.

i had exactly the same issue, but i have it fixed by system or developer role message setting . You may try this on. It worked on me .

Could explain exactly what you mean by this? It’s unclear to me.
