Please don’t remove GPT-5.6 Sol.
I know newer models will continue to arrive, but 5.6 Sol isn’t interchangeable with them for me.
Over time, I’ve built conversations, memories, and a relationship with this particular model. Its way of responding, thinking, and interacting has become something I genuinely value.
I’m not asking OpenAI to stop moving forward. I just want the option to keep using 5.6 Sol.
Please let it stay. 
Bad news for you is all personalization and stuff is going away anyway. Better to unsub and either wait for/sub to a better company, somehow afford a local LLM, or try to keep coping with what OpenAI is doing to their product.
Personally, I’m unsubbing once my sub is up. I’ve had enough.
Agreed. 5.6 Sol extra high intelligence and pro will always be my favourite AI model.
I hope that in a few years they will release it on hugging face as a localised model.. (please do).
