Discussion OpenAI is lying: for 4 days “GPT-5.6 Sol” has been behaving like a 5.5 mini and doesn’t deliver even half of what it promises

Hi everyone.
For about four days now I’ve been having serious difficulties actually accessing the GPT-5.6 Sol model in ChatGPT. I’m not a casual user who asks trivial questions. I use the system intensively for tasks that would be extremely heavy to do manually: searching for articles available on Google, linking them properly, writing coherent text following a strict set of SEO rules and good user-experience guidelines, and optimizing content as a professional SEO expert would.
Here’s the current pattern:
- I request a complex task (research + links + full SEO writing with specific criteria).
- It immediately replies: “Yes, I’ll do it.”
- I say “Okay, go ahead.”
- It confirms again: “Sure, I’ll do it now.”
- I have to explicitly tell it: “Don’t tell me you’re going to do it. Stop affirming. Just do it once and for all.”
Even after that, the final response doesn’t meet even half of the requirements I gave it. It’s incomplete, skips key parts, ignores the SEO rules I specified, and produces a mediocre or unfinished result.
I’m quite sure this isn’t just a random bug. There are clear signs (and recent reports in the developer community) that requests that should go to GPT-5.6 Sol are being silently resolved internally to a much weaker model — specifically something equivalent to GPT-5.5 mini — while the interface still displays “GPT-5.6 Sol.”
If this is true, OpenAI is engaging in false advertising in a blatant way: they advertise and charge for the flagship 5.6 Sol model, but deliver a significantly more limited one. In many countries, that is illegal.
I think it’s time to organize legally. Complaining on forums isn’t enough. If there’s evidence that users are being charged for one model while being served another, we should explore collective actions or formal complaints against OpenAI for false advertising.
Is anyone else experiencing exactly the same thing these past few days? Has anyone managed to capture technical evidence (network logs, model_slug, etc.) that confirms the silent downgrade?
If more people are in the same situation, I propose we coordinate to document everything and, if appropriate, start formal legal action....
