“I've selected 5.5 in general settings but I'm in a chat right now and its using 5.6 sol but I want to use 5.5 thinking and I can't seem to find the option?”
“I asked ChatGPT and it told me with a go subscription I should have access to a model picker under my settings. But I'm not seeing it. Was that a hallucination? Is it possible to select your model or thinking level with "go"? I absolutely hate 5.5 thinking mini which is what I…”
“[ChatGPT] ★★★ 3/5 (v1.2026.202) — The recent update made easily switching between models per chat impossible. You can now select only the level of intelligence for the model that was used last with each chat, but to switch for an old chat between say 5.5 and 5.6 you need to go…”
Multiple users report an inability to modify the ChatGPT model version within the application. This indicates a loss of user control and customization options, frustrating those who rely on specific models for particular tasks.

“Hey y’all, does anyone know if there’s a way to choose a model in the settings and have it permanently there? Right now i have to choose it every time i start a new chat. I want 5.6 but it automatically goes to 6. submitted…”
“My chat is now version 6. I no longer have the option to select which model I'm using. In the selector in the text box I can choose only between the 3 thinking levels, low , medium, high. There is no longer a drop down at the top to pick which model. This is on both Android and the Web interface. There is also no model selection option in settings. In Work mode, the text box selector does allow me to pick model and thinking levels. I am wanting to use 5.6 in chat though. OpenAI states that 5”
“In the mobile app, go to settings (your account pic) > general > intelligence > select GPT-6. [re: GPT-6 selected in Plus, but the Chat says it’s still 5.6-Sol?]”

“thanks..this is so dumb.. They always switch to lower tier model unless u gotta toggle something…..”
“I swear this week they have changed the UI every day. I opened a new chat just now and being told I am on 5.5 despite my Plus plan and being set to high effort (the model switcher where the slider is is now missing completely today). I have found ZERO way to change the model on Android and for the last week or more, the UI has been changing. How hard is it to just settle on something and leave it? Ugh 😫 submitted by /u/behopeyandabide [link] [comments]”

Is it possible to select your model or thinking level with "go"? I absolutely hate 5.5 thinking mini which is what I was being forced to use on a free plan 🥲 it's unusably bad even with custom instructions and does not reference memories and hallucinates a lot so I was desperate to be able to try and use either legacy”
“Btw I'm a plus user. Where are the model selection options on android?? I'm so lost I'm not able to find answers here too. What is instant, medium and high effort? Before we had so many options within models too like standard and extended in high, etc. Someone help submitted by /u/bbekku [link] [comments]”
“Do you use Android? Could you please show me the screenshot of how it looks on your phone?”
“There's nothing there... https://preview.redd.it/y3r06d6s15gh1.jpeg?width=1080&format=pjpg&auto=webp&s=4b9cf65a6bbf39b65137038139c10ac5e7357fdc”
“After you click the plus on the left side of the chat box and choose intelligence, there should be a new icon in the lower right of the chat box that says like 5.5 or 5.6 etc. you should be able to click that icon to change everything to the model and level you want.”
