This is something that’s only started happening more recently, but as a relatively heavy user of antigravity, i’ve noticed many instances where the agent has gotten stuck and just constantly repeats itself, especially annoying if this happens in teamwork-preview where I have to take manual intervention, often not noticing for a while. Seems to be a model issue as i’ve had this happen to me in the IDE, subagents, and just regularly interacting through the 2.0 interface.
Not sure if this an issue in regards to its frequency penalty setting or what. But regardless, it doesn’t seem to be something that I’m able resolve on my end.
Edit - it seems as though this would be directly linked with the recent update of the gemini 3.5 flash model as well.
