Google Nano Banana 2 Edit (Channel Edition)

Nano Banana 2 is Google's Gemini 3.1 Flash image model - the speed-quality hybrid of the lineup that Google insists on calling a fruit. It's a genuinely fast, capable image editor, and it lives behind closed APIs with a Google account and a usage policy. This BizyAirPlus node is the workaround: Google's editing model, reached through BizyAir's channel, inside a normal ComfyUI graph. You don't need a Google account, just BizyAir credits.

What it is

A "Channel Edition" BizyAir node - BizyAir resells access to Google's model, so the API contract and billing are BizyAir's. The I2I (image-to-image) mode is the edit node: images + prompt in, edited image out, with a resolution default of 2K and an aspect_ratio default of 16:9. It's the node for "change this photo's background," "make it a different season," "swap the outfit" - instruction-based editing on a fast modern model.

How it works

Your reference images get uploaded and encoded as context, the prompt drives the edit, and Google's model does the generation remotely. Because it's a modern instruction-based editor (the same family that made Qwen-Image-Edit and Kontext the standard answers to "change this"), edits keep the subject while altering what you ask for. Multiple reference images are supported via the images input, which matters for consistency across edits.

The inputs that matter

• images - required. The picture(s) to edit; more references means more consistency to work from.
• prompt - required. The edit instruction. This is the entire creative surface.
• resolution - 2K by default; drop it for cheaper fast iterations.
• aspect_ratio - output shape, default 16:9.

api_config and skip_error are the standard pack options.

Outputs

image → save/preview. request_id is the cloud job ID. urls are direct links to the edited files.

Installing

ComfyUI Manager → search "BizyAirPlus", or:

cd ComfyUI/custom_nodes
git clone https://github.com/siliconflow/BizyAirPlus.git
cd BizyAirPlus
python -m pip install -r requirements.txt

Restart, toggle the BizyAirPlus button ON, enter your BizyAir API key from bizyair.ai.

Where people get burned

Set expectations honestly: Nano Banana is powerful but the community's verdict is "unimaginative" - it does what you ask, cleanly, without surprising you, and it's aggressively censored (Google's IMAGE_SAFETY filtering got stronger in 2026, and output carries an invisible SynthID watermark). So use it for production edits, not creative wildcards. And watch the bill - 2K renders at metered prices; iterate at lower resolution first. Also, closed-model output is closed-model output: the watermark means you should treat anything you produce commercially with the platform terms in mind.
