Chat Template Kwargs

chat_template_kwargs lets you send provider-specific chat template options with a model request. Agenta stores the value in the model configuration and passes it through unchanged when the prompt is invoked.

Use it only when the selected model provider documents a chat template option you need. Unsupported keys can be ignored or rejected by the provider.

Configure in the playground​

  1. Open your prompt in the playground.
  2. Click the model settings in the prompt configuration panel.
  3. Open Advanced.
  4. Edit Chat Template Kwargs as JSON.
  5. Run the prompt to test the provider behavior.

Example:

{
  "enable_thinking": false
}

The value is optional. If you leave it empty or reset it, Agenta omits chat_template_kwargs from the model request.

Behavior​

Agenta does not treat chat_template_kwargs as prompt content. Prompt variables are not substituted inside this object, so a value like {{provider_flag}} stays literal.

Fallback models have their own model settings. If a fallback model needs different chat template options, configure chat_template_kwargs on that fallback model as well.
