OpenAI DALL·E 3 Node

Learn how to use the OpenAI DALL·E 3 API node to generate images in ComfyUI

OpenAI DALL·E 3 is part of the ComfyUI API Nodes series, allowing users to generate images through OpenAI’s DALL·E 3 model. This node supports text-to-image generation functionality.

Node Overview

DALL·E 3 is OpenAI’s latest image generation model, capable of creating detailed and high-quality images based on text prompts. Through this node in ComfyUI, you can directly access DALL·E 3’s generation capabilities without leaving the ComfyUI interface.

The OpenAI DALL·E 3 node generates images synchronously through OpenAI’s image generation API. It receives text prompts and returns images that match the description.

To use the API nodes, you need to ensure that you are logged in properly and using a permitted network environment. Please refer to the API Nodes Overview section of the documentation to understand the specific requirements for using the API nodes.

If you find missing nodes when loading the workflow file below, it may be due to the following situations:

1. You are not using the latest Development (Nightly) version of ComfyUI.
2. You are using the Stable (Release) version or Desktop version of ComfyUI (which does not include the latest feature updates).
3. You are using the latest Commit version of ComfyUI, but some nodes failed to import during startup.

Please make sure you have successfully updated ComfyUI to the latest Development (Nightly) version. See: How to Update ComfyUI section to learn how to update ComfyUI.

FAQs

Why can't I find the API nodes?

Please update your ComfyUI to the latest version (the latest commit or the latest desktop version). We may add more API support in the future, and the corresponding nodes will be updated, so please keep your ComfyUI up to date.

Please note that you need to distinguish between the nightly version and the release version. In some cases, the latest release version may not be updated in time compared to the nightly version. Since we are still iterating quickly, please ensure you are using the latest version when you cannot find the corresponding node.

Why can't I use / log in to the API Nodes?

API access requires that your current request is based on a secure network environment. The current requirements for API access are as follows:

• The local network only allows access from 127.0.0.1 or localhost, which may mean that you cannot use the API Nodes in a ComfyUI service started with the --listen parameter in a LAN environment.
• Able to access our API service normally (a proxy service may be required in some regions).
• Your account does not have enough credits.

Why can't I use API node even after logging in, or why does it keep asking me to log in while using?

• Currently, only 127.0.0.1 or localhost access is supported.
• Ensure your account has enough credits.

Can API Nodes be used for free?

API Nodes require credits for API calls to closed-source models, so they do not support free usage.

How to purchase credits?

Please refer to the following documentation:

1. Comfy Account: Find the User section in the settings menu to log in.
2. Credits: After logging in, the settings interface will show the credits menu. You can purchase credits in Settings → Credits. We use a prepaid system, so there will be no unexpected charges.
3. Complete the payment through Stripe.
4. Check if the credits have been updated. If not, try restarting or refreshing the page.

Are unused credits refundable?

Currently, we do not support refunds for credits. If you believe there is an error resulting in unused balance due to technical issues, please contact support.

Can credits go negative?

Credits cannot go negative, so please ensure you have enough credits before making the corresponding API calls.

Where can I check usage and expenses?

Please visit the Credits menu after logging in to check the corresponding credits.

Is it possible to use my own API Key?

Currently, the API Nodes are still in the testing phase and do not support this feature yet, but we have considered adding it.

Do credits expire?

No, your credits do not expire.

Can credits be transferred or shared?

No, your credits cannot be transferred to other users and are limited to the currently logged-in account, but we do not restrict the number of devices that can log in.

Can I use the same account on different devices?

We do not limit the number of devices that can log in; you can use your account anywhere you want.

How can I request for my account or information to be deleted??

Email a request to [e-mail] and we will delete your information
