Google AI Studio’s API keys, nano banana 2 cannot generate 4K quality images, only 512K-2K quality.
The type of apikeys is: Level 1 · Post-paid. An unknown issue has occurred; it is not clear if others are experiencing the same problem, with the error message: 503.
Last week, I was able to use the same apikey to generate 4K images.
It may be that the policy has changed, but Google did not notify it. Now if we want to generate 4K pictures, how should we solve it?
