Ace Chat by Ace Data Cloud

Ace Chat for ComfyUI by Ace Data Cloud

Use a dynamic model ID with Ace Data Cloud's chat completions API from a ComfyUI graph. This package mirrors ModelProviderDify, whose model is configured by an exact ID rather than a finite selector. A read-only node lists the IDs currently returned for your Ace key. Chat completions may consume Credits at the current model price.

| Node | Purpose | | --- | --- | | Ace Chat List Models | Read /v1/models and optionally filter IDs; no chat generation | | Ace Chat Completion | Send one non-streaming /v1/chat/completions request using an exact model ID |

The chat node returns assistant text, tool calls JSON, usage JSON, response ID, and response model as standard ComfyUI strings. model_id is free text so newly available IDs are not blocked by a stale package enum. The model list can include IDs that use another API surface; choose a chat-compatible ID and check its current access and price. The node returns function tool calls but does not execute those functions.

Install

When the Registry version is active, open ComfyUI-Manager → Custom Nodes, search Ace Chat, confirm publisher acedatacloud and package Ace Chat by Ace Data Cloud, install, and restart. Registry ID: ace-chat; source: AceDataCloud/AceChatComfyUI. Source availability or Registry upload alone does not prove Manager installation.

For local source testing:

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

Restart ComfyUI and search for Ace Chat.

Set your key

Set an Ace key with chat access in the actual ComfyUI process environment, then 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 /v1/models and /v1/chat/completions.

Choose a model and chat

Import 01-list-models.json with File → Open and run it. This is a read-only request. Copy an exact chat-compatible ID into Ace Chat Completion. The Dify provider uses the same fixed /v1 endpoint and a customizable model ID; this ComfyUI node follows that contract. The model list can change without a package release.

Import 02-chat-completion.json, check the selected model's price, and run once. The example is a paid-call template. prompt plus optional system_prompt creates a simple conversation. messages_json can instead contain a full nonempty JSON message array; when present it takes precedence over those two fields. tools_json can provide an OpenAI-compatible function tool array. A temperature of -1 omits the parameter and uses the model default; max_tokens limits output.

If the paid request times out, inspect Ace request history before another run. The node does not automatically retry chat submissions. To inspect current usage, use the Ace Data Cloud Console. See privacy notes.

Development

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

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