ComfyUI Node: ChatGPT Prompt Node

ChatGPT Prompt Node:

The ChatGptPrompt node is designed to facilitate seamless integration with OpenAI's GPT models, allowing you to generate creative and contextually relevant text prompts. This node is particularly useful for AI artists who want to leverage the power of GPT models to enhance their creative workflows. By providing a prompt, selecting a model, and defining a role, you can generate text that aligns with your artistic vision. The node also offers optional parameters to append additional strings to the prompt and set a seed for reproducibility. This flexibility makes it a valuable tool for generating unique and varied text outputs, which can be used in various creative projects.

ChatGPT Prompt Node Input Parameters:

prompt

The prompt parameter is a required multiline string input where you can enter the initial text or question you want the GPT model to respond to. This serves as the primary input that guides the model in generating the output. The quality and specificity of the prompt can significantly impact the relevance and creativity of the generated text.

model

The model parameter allows you to select the specific GPT model you want to use for generating the text. The default model is gpt-3.5-turbo-1106, but you can choose from a list of available models. Different models may offer varying levels of complexity and creativity, so selecting the right model can enhance the quality of the output.

role

The role parameter defines the role or persona the GPT model should adopt while generating the text. The default role is AI Assistant, but you can choose from a list of predefined roles. This parameter helps in tailoring the generated text to fit a specific tone or style, making it more aligned with your creative needs.

append_string

The append_string parameter is an optional multiline string input that allows you to add additional text to the end of the prompt. This can be useful for providing extra context or instructions to the model, thereby refining the generated output.

seed

The seed parameter is an optional integer input that sets the seed for the random number generator used by the GPT model. The default value is 0, and it can range from 0 to 0xffffffffffffffff. Setting a seed ensures that the same prompt will generate the same output, which is useful for reproducibility.

ChatGPT Prompt Node Output Parameters:

STRING

The output of the ChatGptPrompt node is a single string that contains the text generated by the GPT model. This output can be used directly in your creative projects or further processed to fit your specific needs. The generated text is influenced by the input parameters, making it a versatile tool for various applications.

ChatGPT Prompt Node Usage Tips:

• Experiment with different prompts and roles to see how the generated text varies. This can help you find the best combination for your specific project.
• Use the append_string parameter to add additional context or instructions to the prompt, which can help in generating more relevant and creative outputs.
• Set the seed parameter if you need reproducible results. This is particularly useful when you want to generate the same text output for a given prompt in different sessions.

ChatGPT Prompt Node Common Errors and Solutions:

Error: OpenAI API key file not found OpenAI features wont work for you

• Explanation: This error occurs when the configuration file containing the OpenAI API key is missing or cannot be read.
• Solution: Ensure that the config.json file is present in the correct directory and contains a valid OpenAI API key.

Error: Failed to talk to OpenAi. sleeping for 10 seconds and trying again

• Explanation: This error indicates that the node failed to communicate with the OpenAI API, possibly due to network issues or API rate limits.
• Solution: Check your internet connection and ensure that your API key is valid. The node will automatically retry up to three times.

Error: OpenAI API key is invalid OpenAI features wont work for you

• Explanation: This error occurs when the provided OpenAI API key is invalid or has expired.
• Solution: Update the config.json file with a valid OpenAI API key and restart the node.

Error: Cannot execute because node <class_type> does not exist

• Explanation: This error occurs when the specified node class type is not found in the node mappings.
• Solution: Ensure that the node class type is correctly defined and that the node mappings are properly configured.
