gemini-3-pro-image (Nano Banana Pro) hitting 503 at 4K · Google compute congested
The root cause is a performance/compute issue on Google’s side: gemini-3-pro-image frequently returns 503 at 4K. To be clear — this is not an account-pool issue: it still returns 503 even when the account has quota left, so it’s genuinely compute congestion on the official side; Google’s lane is crowded right now.
Current status by resolution / model (pick whichever fits):
gemini-3-pro-image(Nano Banana Pro) 4K: frequent 503gemini-3-pro-image(Nano Banana Pro) 2K: relatively normal; 2K is a reasonable choice unless 4K is requiredgemini-3.1-flash-image(Nano Banana 2): currently more stable
