ComfyUI Node: Chat completion _O

Chat completion _O:

The Chat completion _O node is designed to facilitate the creation of chat completions using OpenAI's ChatGPT models. This node allows you to generate responses based on a series of input messages, leveraging the powerful language capabilities of models like GPT-3.5-turbo. It is particularly useful for creating interactive AI-driven conversations, automating customer support, or generating creative content. By integrating this node into your workflow, you can harness the advanced natural language processing capabilities of OpenAI's models to produce coherent and contextually relevant responses.

Chat completion _O Input Parameters:

client

The client parameter represents the OpenAI client instance that is used to interact with the OpenAI API. This client is essential for making requests to the API and retrieving responses. It must be properly configured and authenticated to ensure successful communication with the OpenAI servers.

model

The model parameter specifies the OpenAI model to be used for generating chat completions. The default value is "gpt-3.5-turbo", but you can choose from other available models depending on your needs. This parameter determines the language model's behavior and the quality of the generated responses.

messages

The messages parameter is a collection of input messages that form the conversation history. These messages guide the model in generating appropriate responses. Each message should include a role (e.g., user, assistant, system) and content. The quality and relevance of the generated completion depend heavily on the context provided by these messages.

seed

The seed parameter is optional and allows you to set a specific seed value for the random number generator. This can be useful for ensuring reproducibility of results. The default value is 0, and it can range from 0 to 0xffffffffffffffff.

Chat completion _O Output Parameters:

STRING

The STRING output parameter provides the generated response from the chat completion as a plain text string. This output is useful for displaying the response directly to users or for further processing in your application.

OPENAI_CHAT_COMPLETION

The OPENAI_CHAT_COMPLETION output parameter contains the full chat completion object returned by the OpenAI API. This object includes detailed information about the generated response, such as the choices made by the model and any additional metadata. It is useful for debugging, logging, or advanced processing.

Chat completion _O Usage Tips:

• Ensure that the client parameter is correctly configured and authenticated to avoid connection issues with the OpenAI API.
• Provide clear and contextually rich messages in the messages parameter to improve the quality of the generated responses.
• Experiment with different models using the model parameter to find the one that best suits your needs.
• Use the seed parameter to achieve consistent results when running the same input multiple times.

Chat completion _O Common Errors and Solutions:

ConnectionError

• Explanation: This error occurs when the node fails to connect to the OpenAI API.
• Solution: Ensure that your internet connection is stable and that the client parameter is correctly configured and authenticated.

InvalidModelError

• Explanation: This error occurs when the specified model in the model parameter is not recognized by the OpenAI API.
• Solution: Verify that the model name is correct and that it is available in your OpenAI account.

InvalidMessagesFormat

• Explanation: This error occurs when the messages parameter is not formatted correctly.
• Solution: Ensure that each message in the messages parameter includes a valid role and content.

APIRequestError

• Explanation: This error occurs when there is an issue with the API request, such as exceeding rate limits or invalid API keys.
• Solution: Check your API usage limits and ensure that your API key is valid and has the necessary permissions.
