In the past I've usually found that Gemini (pro, flash) would get stuck on a problem and then seemingly start to do some kind of random search trying this and that just burning through tokens. When this would happen I'd switch (in antigravity) to Claude sonnet 4.6 and it would cut right to the chase and find the problem quickly. But the other day I was out of Claude tokens so I went back to Gemini 3.1 Pro and asked about a verilog simulation problem that Claude had been stuck on - and it figured it out in a few minutes.
