CoherePrompt

What is it?

The CoherePrompt node sets up a connection to Cohere's AI models.

When would I use it?

Use this node when you want to:

  • Use Cohere's AI models in your workflow
  • Take advantage of Cohere's specific capabilities

How to use it

Basic Setup

  1. Add the CoherePrompt node to your workflow
  2. Connect its output to nodes that can use prompt drivers (like Agent)

Parameters

  • model: The Cohere model to use (default is "command-r-plus")
  • max_attempts_on_fail: How many times to retry if there's an error
  • use_native_tools: Whether to use Cohere's built-in tools
  • max_tokens: Maximum length of responses
  • p: Controls diversity of outputs (similar to temperature)
  • k: Controls focus on most likely tokens
  • temperature: Controls randomness in responses (higher values = more creative, lower = more focused)
  • stream: Whether to receive responses as they're generated (true) or all at once (false)

Outputs

  • prompt_model_config: The configured Cohere driver that other nodes can use

Example

If you want to create an agent that uses Cohere:

  1. Add a CoherePrompt node to your workflow
  2. Connect the "driver" output to an Agent's "prompt_driver" input

Try:

  1. Set "model" to something besides the default
  2. Set "max_tokens" to 1000 (for moderate length responses)

Important Notes

  • You need a valid Cohere API key set up in your environment as COHERE_API_KEY
  • The default model is "command-r-plus"
  • The node checks if your API key is valid during setup

Common Issues

  • Missing API Key: Make sure your Cohere API key is properly set up
  • Connection Errors: Check your internet connection and API key validity
