Nano Banana by Ace Data Cloud

Nano Banana for ComfyUI by Ace Data Cloud

Generate or edit images with Nano Banana, retrieve the same task ID, and load the completed image into ComfyUI's standard IMAGE type. These nodes call a hosted Ace Data Cloud API; no local model or GPU is needed. Generation and editing consume Ace Data Cloud Credits at the current service price.

| Node | Purpose | | --- | --- | | Nano Banana Generate Image | Submit one paid text-to-image task | | Nano Banana Edit Image | Submit one paid edit using public HTTPS reference image URLs | | Nano Banana Retrieve Task | Query or wait for the same task ID | | Nano Banana Retrieve Tasks | Read multiple existing task IDs without new generation | | Nano Banana Load Image / Load Images | Decode one result URL or a URL array into ComfyUI IMAGE |

The package offers all nine model IDs currently listed by the Ace Data Cloud Dify Nano Banana plugin:

nano-banana, nano-banana-2-lite, nano-banana-2, nano-banana-2.1, nano-banana-pro, nano-banana:official, nano-banana-2-lite:official, nano-banana-2:official, and nano-banana-pro:official.

Model availability, resolution limits, and pricing can differ. Check the current service documentation before a paid run. nano-banana and nano-banana-2-lite support only 1K; choose a model that supports 2K or 4K when requesting those sizes. A count of 1–4 is available; the Load Images node returns a batch when the output images have matching dimensions.

Install

When the Registry version is active, open ComfyUI-Manager → Custom Nodes, search Nano Banana, confirm publisher acedatacloud and package Nano Banana by Ace Data Cloud, then install and restart ComfyUI. The planned Registry ID is nano-banana; the source repository is AceDataCloud/NanoBananaComfyUI. Source availability does not prove Registry or Manager discoverability.

For local source testing:

cd /path/to/ComfyUI/custom_nodes
git clone https://github.com/AceDataCloud/NanoBananaComfyUI.git
cd NanoBananaComfyUI
python -m pip install -r requirements.txt

Restart ComfyUI and search the node picker for Nano Banana. The package uses ComfyUI's existing PyTorch, NumPy, and Pillow installation for image decoding.

Set your Ace Data Cloud key

Use an application key with Nano Banana access. Set it in the ComfyUI process environment and restart:

export ACEDATACLOUD_API_KEY='paste-your-key-here'
python main.py --cpu

ACEDATACLOUD_API_TOKEN is also accepted. Keep the key out of workflows, screenshots, issues, and the repository. If you restrict API paths, allow /nano-banana/images and /nano-banana/tasks.

Generate and retrieve

Import 01-submit-nano-banana.json with File → Open, choose a model and price, then run it once. Copy the task ID from Preview as Text. A submitted task is not a completed image. If submission times out without a task ID, check Ace request history before paying for another generation.

Import 02-retrieve-and-preview.json, replace the placeholder task ID, and run it. It connects Retrieve Task → Load Images → Preview Image. Retrieve waits up to 240 seconds for the same ID. If still pending, rerun only the retrieve workflow. A finished task supplies image URLs; Load Images decodes them into a normal ComfyUI image batch.

For editing, import 03-edit-nano-banana.json and replace its placeholder source URL with a public HTTPS reference image. You can also enter a JSON array or one URL per line. It uses the same /nano-banana/images endpoint with action: edit. Reuse the retrieval workflow for the returned task ID. Reference images are submitted to Ace Data Cloud for processing.

Check usage and troubleshoot

Check the submitted task or trace ID in the Ace Data Cloud Console. Read-only task queries and media downloads should not create another generation.

| Symptom | Action | | --- | --- | | Key missing | Put ACEDATACLOUD_API_KEY in the actual ComfyUI process environment, then restart. | | HTTP 401/403 | Check key validity, service access, path restrictions, and content policy. | | HTTP 429 | Wait for the service limit; keep any accepted task ID. | | Pending | Query the same task ID again, without rerunning Generate or Edit. | | Submission timeout or HTTP 5xx | Inspect request history before resubmitting; the paid task may have been accepted. | | Image download error | Confirm the task succeeded and its Ace media URL is available. |

The nodes send prompts and reference URLs to api.acedata.cloud; completed images are downloaded from Ace CDN. See privacy notes. Only submit content you have permission to process.

Development

python -m unittest discover -s tests -v
python -m py_compile __init__.py client.py nodes.py

pyproject.toml declares the short Registry ID nano-banana, publisher acedatacloud, and a 400×400 proportional resize of the canonical Ace logo.
