# DeepSeek Chat Model node
|
||||
|
||||
Use the DeepSeek Chat Model node to use DeepSeek's chat models with conversational agents.
|
||||
|
||||
On this page, you'll find the node parameters for the DeepSeek Chat Model node and links to more resources.
|
||||
|
||||
/// note | Credentials
|
||||
You can find authentication information for this node [here](/integrations/builtin/credentials/deepseek/).

|
||||
|
||||
## Node parameters
|
||||
|
||||
### Model
|
||||
|
||||
Select the model to use to generate the completion.
|
||||
|
||||
n8n dynamically loads models from DeepSeek and you'll only see the models available to your account.
|
||||
|
||||
## Node options
|
||||
|
||||
Use these options to further refine the node's behavior.
|
||||
|
||||
### Base URL
|
||||
|
||||
Enter a URL here to override the default URL for the API.
|
||||
|
||||
### Frequency Penalty
|
||||
|
||||
Use this option to control the chances of the model repeating itself. Higher values reduce the chance of the model repeating itself.
|
||||
|
||||
### Maximum Number of Tokens
|
||||
|
||||
Enter the maximum number of tokens used, which sets the completion length.
|
||||
|
||||
### Response Format
|
||||
|
||||
Choose **Text** or **JSON**. **JSON** ensures the model returns valid JSON.
|
||||
|
||||
### Presence Penalty
|
||||
|
||||
Use this option to control the chances of the model talking about new topics. Higher values increase the chance of the model talking about new topics.
|
||||
|
||||
### 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.
|
||||
|
||||
### Timeout
|
||||
|
||||
Enter the maximum request time in milliseconds.
|
||||
|
||||
### Max Retries
|
||||
|
||||
Enter the maximum number of times to retry a request.
|
||||
|
||||
### Top P
|
||||
|
||||
Use this option to set the probability the completion should use. Use a lower value to ignore less probable options.
|
||||
|
||||
