We were using gpt-4o for our chat agent, and after some experiments I think we'll move to flash 2.0. Faster, cheaper and a bit more reliable even. I also experimented with the experimental thinking version, and there a single node architecture seemed to work well enough (instead of multiple specialised sub agents nodes). It did better than deepseek actually. Now I'm waiting for the official release before spending more time on it.
