`Error: Unable to contact model provider` for GPT-5 (non-codex) family of models

colinrsmall · November 11, 2025, 7:15pm

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I am unable to use any of the GPT-5 (non-codex) family of models within the Cursor IDE, either by providing my own key or using my Cursor credits. Using my own key reproduces the same prompt-cache-retention error that has already been documented (Issue when using custom OpenAI Key with GPT 5 High Fast). Using my Cursor credits displays a non-informative Unable to contact model provider error. Depending on how Cursor catches and displays errors to the user, it might be the same prompt-cache-retention error that is breaking GPT-5 in both modes (just with BYOK displaying a more informative error message).

Steps to Reproduce

Select a GPT-5 family model (high/fast, medium/normal, etc.)
Submit any prompt into the prompt message box

Expected Behavior

The prompt should be handled normally.

Operating System

MacOS

Current Cursor Version (Menu → About Cursor → Copy)

GPT-5 family

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey, thanks for the report. You’re right - this looks like the same “prompt_cache_retention” bug affecting both paths. The BYOK issue is under investigation: Cursor is sending parameters that GPT‑5 High/Fast/Medium/Normal don’t support, and in your case gpt models also don’t work with your subscription.

Could you test this workaround?

Disable your OpenAI API key (if enabled)
Try GPT‑5 Codex with your Cursor credits
Let me know if it works

Additional debugging steps:

If you have MCP servers enabled, try disabling them temporarily
Check for errors in DevTools console (Help > Toggle Developer Tools)

GPT‑5 Codex is confirmed to work with BYOK, but I need to verify if it also works with Cursor credits. If Codex also fails when using credits, that points to a broader issue that needs escalation.

colinrsmall · November 12, 2025, 7:02pm

Sorry, should have been more clear in the original post. I can confirm that GPT-5 Codex works fine while using Cursor credits. Have also tried disabled my MCP servers and that has not fixed the other GPT-5 models not being accessible.

and in your case gpt models also don’t work with your subscription.

I’m on the $20/mo. Pro tier. That should give me access to GPT/other OpenAI models, right?

Here are the logs from the dev console while using GPT-5 with my Cursor credits, but I don’t see anything too enlightening:
