+# Cohere Chat Model node
+
+Use the Cohere Chat Model node to access Cohere's large language models for conversational AI and text generation tasks.
+
+On this page, you'll find the node parameters for the Cohere Chat Model node, and links to more resources.
+
+/// note | Credentials 
+You can find authentication information for this node [here](/integrations/builtin/credentials/cohere.md).

+
+## Node parameters
+
+* **Model**: Select the model which will generate the completion. n8n dynamically loads available models from the Cohere API. Learn more in the [Cohere model documentation](https://docs.cohere.com/v2/docs/models#command).
+
+## Node options
+
+* **Sampling Temperature**: Use this option to control the randomness of the sampling process. A higher temperature creates more diverse sampling, but increases the risk of hallucinations.
+* **Max Retries**: Enter the maximum number of times to retry a request.
+
