Nano Banana Pro hitting 503 at 4K · Google compute congested

2026/6/24 10:57 (UTC+8) · Model Status · Google ⚠️ 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 503
gemini-3-pro-image (Nano Banana Pro) 2K: relatively normal; 2K is a reasonable choice unless 4K is required
gemini-3.1-flash-image (Nano Banana 2): currently more stable

We keep tracking the recovery of Google’s compute and will sync progress — thanks for your patience.
