Using Google Antigravity and Google AI Studio, I have noticed that Gemini models, which includes 3.1 Pro and 3.5 Flash, are increasingly stucking in thinking loops. It has become much more common. So I did a 100 tasks test and out of them, 3.5 Flash got stuck in a loop 23 times, while 3.1 Pro was a lower 16 times.
Was this not the case earlier? I've had it stuck in loops from day 1, even when Gemini 3 came out. I've never been able to actually use it for anything because it goes absolutely mental after a handful of turns.
I find when I use Gemini Web Chat that it often just starts over mid-conversation and doesn't remember the rest of the context of the conversation whereas Claude and ChatGPT never do that.
I have the website which I built in which it got stuck in a thinking loop. But it won't show any of the 100 tests I did. I am thinking of writing an article on this though. If you want to see, the site's Nasengetu. It is indexed so you can find it in Google search.
I have multiple examples. Just yesterday, when I was trying to implement a caching system for my website Nasengetu, and it completely stuck in a loop-where it runs a log fetch using the git command and then thinks about the result, then runs the command again, and think again. And this repeated until I stopped it when it almost completely exhausted my five hour request limit.
