Bug: 4K Image Option Missing from Dropdown in Google AI Studio Web UI

30-06-2026 (Started around 6:00 PM IST)
I was generating 4K images perfectly fine until 6:00 PM today (June 30). Suddenly, the 4K option completely disappeared from the settings dropdown menu. Right now, only the 1K option is showing up.

I haven’t changed any of my settings or my account type. It feels like a quick bug or a glitch from a recent evening update.

Can you please check if the 4K and 2K options can be brought back to the menu?

Attached is the screenshot for your reference.
Thanks!

HI @Vishal_Pisote

The current model selected is 3.1 Flash lite Image(https://ai.google.dev/gemini-api/docs/models/gemini-3.1-flash-lite-image) , which only supports 1k images
For 4k and 2k images you can use 3.1 Flash Image (https://ai.google.dev/gemini-api/docs/models/gemini-3.1-flash-image)
