2026/10/23 11:21 (UTC+8) · New Model · Google 🚀 The community ComfyUI node Comfyui-LuckNanoBananaPro now supports Nano Banana 2.1 The author luckdvr updated the plugin on 2026-10-23: gemini-nano-banana-2.1 is added to the model dropdown and is the default for newly created nodes, while gemini-3.1-flash-image-preview, gemini-3-pro-image-preview and gemini-2.5-flash-image remain available. Existing workflows do not switch automatically — to use NB2.1, just pick it in the model dropdown of your existing node. How the node behaves with NB2.1:
  • Resolutions 1K / 2K / 4K are supported; 512 is not
  • It waits at least 360 seconds; for 4K or multi-image editing, set the timeout to 600 seconds
  • 429 / 503 / connection-setup timeouts are retried with backoff; after a read timeout or disconnect it stops auto-resending — the server may still be generating and billing, so check your call logs before re-running
