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

+
+## Node parameters
+
+### Model
+
+Select the model to use to generate the completion.
+
+n8n dynamically loads models from the AI Gateway and you'll only see the models available to your account.
+
+## Node options
+
+Use these options to further refine the node's behavior.
+
+### Frequency Penalty
+
+Use this option to control the chance 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 chance 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. 
+
+### Reasoning Effort
+
+Use this option to enable model reasoning processes through thinking/reasoning tokens, if supported.
