# Reasoning capabilities
<a name="reasoning-capabilities"></a>

Amazon Nova 2 Lite supports extended thinking, which is disabled by default. When enabled, the model generates internal reasoning tokens that improve response quality. In Amazon Nova 2 Lite, reasoning content is redacted in the output and displays as `[REDACTED]`, though you are still charged for these tokens.

The reasoning field is included in the response structure to preserve the option of exposing this content in future releases. For more information about extended thinking, see [Extended thinking in Amazon Nova 2](extended-thinking.md) and [Code library](code-library.md).
