Symbiotica Wavespeed Nano Banana 2 Edit Fast

Last of the four Nano Banana 2 wrappers, and the least interesting on paper - but it's the one that maps to a real workflow. It's the Edit node's fast lane: same Google Gemini 3.1 Flash image model over Wavespeed, same up-to-14 reference images, fewer knobs, and a shorter default timeout because the fast endpoint is supposed to get back to you sooner. Use it when you're iterating on an edit - trying several prompts against the same reference sheet - and use the full Edit node when the result matters.

The mechanism is identical to the other three: images and prompt are posted to google/nano-banana-2/edit-fast on Wavespeed's API, the node polls until the task completes, and the first output image comes back as a ComfyUI IMAGE.

What's different from the full Edit node

• resolution only offers 2k (default) and 4k.
• No enable_image_search - web-search grounding only (enable_web_search, off by default).
• timeout defaults to 180s instead of 300.

Everything else matches the Edit node: images (up to 14; bigger batches truncate with a console note), prompt (required, non-empty), aspect_ratio, output_format (png/jpeg), optional api_key. Outputs are the usual trio - image, task_id, result_url.

Install

One node of the Symbiotica pack:

cd ComfyUI/custom_nodes
git clone https://github.com/symbiotica-ai/comfyui-nodes.git symbiotica
pip install -r symbiotica/requirements.txt

Restart ComfyUI, or ComfyUI Manager → search Symbiotica → install. Needs a Wavespeed key - Settings → Symbiotica, or export WAVESPEED_API_KEY=.... No model downloads for this node.

Common issues

• Timeouts at 180s - fast endpoint or not, 4K edits with web search can run past the default. Bump timeout.
• Silent 14-image truncation - feed a big batch and only the first 14 frames go. For template-pipeline work, pass the sheets, not the whole folder.
• Refused edits - Google's filter applies at the model. Nothing the node can do about that; it's the cost of a closed model.

Four variants, one model, and a sensible division of labor: full node for the keepers, Fast for drafts. The EditFast is the draft lane for edits, and that's all it needs to be.
