# Nano Banana Pro/2 at 2K and 4K Now Usable · Concurrency Scaled Up

> Following the Vertex failover: 2K and 4K on Nano Banana Pro (gemini-3-pro-image) and Nano Banana 2 (gemini-3.1-flash-image) are now confirmed generating normally, and we've added more concurrency — the earlier ~100 RPM cap on the temporary Vertex route has been relaxed, so you can call it freely; we're still watching for AIStudio to recover and route back to the regular channel.

✅ **Nano Banana Pro / 2 at 2K and 4K now usable · concurrency scaled up**

Following the [Vertex failover](/en/live/2026-06/nano-banana-2k-4k-via-vertex): 2K / 4K on `gemini-3-pro-image` (Nano Banana Pro) and `gemini-3.1-flash-image` (Nano Banana 2) are now confirmed generating normally, and we've added more concurrency — the earlier \~100 RPM cap on the temporary `Vertex` route has been relaxed, so you can call it freely.

Nothing changes on your side — keep using your existing key and just call it directly.

We're still watching for `AIStudio` to recover and will route back to the regular channel, syncing an update the moment it changes.
