# Nano Banana Pro/2 Blurry at 4K and 2K · 1K Normal
> Since this morning, Nano Banana 2 / Pro (gemini-3.1-flash-image, gemini-3-pro-image) have returned blurry images; 4K and 2K are now near-constant while 1K is still fine. Assessed as a 100% Google-side issue. Meanwhile you can use gpt-image-2-vip, the official-relay gpt-image-2, or 1K output while waiting for Google to recover.

⚠️ **Nano Banana Pro / 2 blurry at 4K and 2K · 1K still normal · Google-side issue**
Since this morning, `gemini-3-pro-image` (Nano Banana Pro) and `gemini-3.1-flash-image` (Nano Banana 2) have been returning blurry images; by now **4K / 2K are near-constant** while **1K is still fine**. We assess this as a 100% Google-side issue, not an APIYI channel factor.
Other image channels you can use meanwhile (pick as needed, status below):
* `gpt-image-2-vip`: regained its `size` parameter last night, supports 2K / 4K
* official-relay `gpt-image-2`: billed by tokens, same price as OpenAI's official site
* Nano Banana series at 1K: 1K resolution still generates normally
We'll sync an update the moment Google recovers. For consumer-facing products, it's worth integrating multiple models so you can switch at any time.
