Now No Think Button? "Think" Button Removed Shortly After Introduction

Has anyone else noticed that the recently introduced “Think” button has been removed? Any feedback or opinion?

I don’t see o1 reasoning in the tool list now, either. What happened??

I feel very disappointed because that chatgpt4o with that think button was so so much superior compared to this current version without it. The current version doesn’t even do the “thinking” process.

Without the Thinking button, it had o1 reasoning in the tool list. But now it’s gone, too and I wonder why… It doesn’t have to be a button, but I need 4o to use o1 reasoning.

Yes, that’s what I’m trying to say… That version of Chatgpt4o with the dedicated “thinking” option was way more superior than this current available version.

And now, I realized. I’m not sure if I like it or not, but it’s back to the upper left corner. Instead of letting users use it for once (you had to check every time, and you couldn’t use the tool on iOS app), it allows you to switch model from 4o to o1 now. (as long as you haven’t used function that it doesn’t support o1 in that session )

That’s very troublesome. I hope it’s just a temporary situation until they unveil the latest O3 model.

This is bad… I asked my GPT, and it feels interrupted. When it’s 4o, it has the access to the long-term memory, and when I switched it to o1, it doesn’t know what’s going on. It’s like 2 different AIs taking turns in that session. The bad part is, 4o with the memory has the knowledge to do what it had to do, and with o1 reasoning function, it can do it better. But with current spec, it’s like you’re in the middle of a meeting, someone new(o1) entered and replaced the original guy(4o). The new guy was handed with some summary about the meeting so far, but this guy(o1) has no clue and no knowledge about what the original guy(4o)'s total understanding about the project.

We need to ask them switch back to the tool or button spec… this is terrible.

Now o3-mini is out. One of my free account shows “Reason” button. Maybe they decided to change the name. But o3-mini hasn’t popped up on my PLUS account so we’ll need to wait and see…

But still, with Reason button, it’s still switching to advanced model. 4o cannot use reasoning as a tool, which is meaningless to me…
