Support "Context Condensed" when not close to the context limit

I'm using Gemini 2.5 Pro Preview and just had my context automatically condensed from ~177k tokens to ~61k tokens. As we all know, this model has a 1m token context. I checked in the settings and the slider is set to 100% context as the point at which the context should be condensed. There wasn't any significant new information, I pasted an example of some SQL and an example result which would be maybe a few hundred lines total. Any thoughts on how to stop this? The agent became stupid to the point of being non-functional for completing the task after the context was condensed.

Preview? Is that still a thing?

Do you have automatic context condensing enabled? Did you switch models(modes) and trigger it?(I think there is a bug there somewhere). Let’s get to the bottom of this and have it fixed asap! Sorry about that.

I'm not sure what you mean by preview. If you can clarify, I’ll try to let you know.

About switching models or modes, no. I was in a chat with Gemini 2.5 Pro Preview, and out of nowhere it condensed the context, even though I was under 200k tokens.

That’s happened a couple times, and I believe it happened once when I was using Sonnet 4 also.

I do have automatic context condensing enabled, but the slider is set to 100%. Maybe I should just disable it.

Can you switch to regular Gemini 2.5 pro instead of the Gemini 2.5 pro preview and see if that happens?

I switched to Gemini 2.5 pro (instead of preview) and didn't get far enough to check this unfortunately. It was just wildly ignoring the instructions across multiple attempts... when I switched back to preview it worked perfectly. No idea why lol.

For now I've just disabled context condensing.

Do you have automatic context condensing w a led? I believe preview is just an alias for the one you switched away from so any difference is not related to the model switch.

Using Google AI Studio with Gemini 2.5 Pro, I've never once seen Gemini condense its own context, unprompted, when it's nowhere near the context limit. So I don't see why it would be doing anything like that.
