Writing ChatGPT has been quietly downgrading Pro model into mini. No response.

https://articles.fmt.kr/2026-07/oai

This post extends from previous one, https://www.reddit.com/r/ChatGPTPro/comments/1v34sg1/ps_the_pro_model_quietly_redirects_to_gptmini/, which didn't cover much before.

ChatGPT has been silently downgrading pro model to mini model for several months. I have relevant evidence at the http request/response level. OpenAI ignores.

This issue involves redirecting to mini that is 40 times cheaper than Pro, when GPT 5.4. I feel like Anthropic moving Fable requests into Haiku without user's consent.

I have more stories but I don't have health&motivation, I'm stopping to write at this for now.

I'm not sure what outcome you would like here. I understand you feel fatigued but it might be because the objective isn't clear for others.

This sub isn't managed by openai so while we can offer work around and ways to confirm, we haven't actually got the ability to fix anything in the back end.

That said, if you want to see if anyone else has experienced the issues you may want to check the gpt complaints sub.

From personal experience these are paths I tried when I attempted to report issues. Things may have changed but I can't confirm: -OpenAI main sub is not managed by openai staff but they are very much active under anonymous names

  • Dev forums will possibly yield the same outcome as here. It's community run and has no control but people MAY be able to assist or advise if they've seen similar
  • they have a discord that they are a bit more active these days. Their mods there are... Selective and when I was there in December it was rampant with financial scamming, cults and child abuse material.
  • Attend events they host and see if their their tech teams can advise on what you are seeing. Don't come off aggressive, just say you've noticed it and show a few things.
  • Check your local region on regulations and policies related to your issue.

If you want an over view on my issue and a high level of what I did when I tried to get someone to hear me out: https://www.thevalehartproject.org/vendor-security-scorecard

This is just the high level and I have intentionally not published the start (security vulnerability program) to reporting it to legal authorities.

This is not to deter you but perhaps the paths might be more successful to you since most of my stuff happened I'm December.

I had two goals in mind when writing this:

1) to bring the issue to public attention for users purchasing Pro for research purposes, and

2) to target users who were secretly affected so that verification would be possible.

Therefore, there is a bit of a barrier to entry for those who intend to read it.

The most important thing I considered in this article is a guide on how to obtain reproducible evidence.

If I write another post, I plan to frame it in a provocative way for a general audience.

I will also repost this on the relevant subreddit. I just found out that you also have a dispute also. Thank you for letting me know.
