**Note**  
Before you can take advantage of the generative AI features, you must fulfill the following prerequisites  
For information about pricing for using Amazon Bedrock, see [Amazon Bedrock pricing](https://aws.amazon.com/bedrock/pricing/).
Turn on the generative AI capabilities for your bot locale. To do so, follow the steps at [Optimize Lex V2 bot creation and performance by using generative AI](generative-features.md). 

You can take advantage of Amazon Bedrock FMs to help answer customer questions in a bot conversation. Amazon Lex V2 offers a built-in `AMAZON.QnAIntent` that you can add to your bot. This intent harnesses generative AI capabilities from Amazon Bedrock by recognizing customer questions and searching for an answer from the following knowledge stores (for example, **Can you provide me details on the baggage limits for my international flight?**). This feature reduces the need to configure questions and answers using task-oriented dialogue within Amazon Lex V2 intents. This intent also recognizes follow-up questions (for example, **What about domestic flight?**) based on the conversation history and provides the answer accordingly.

Ensure that your IAM role has the proper permissions to access the `AMAZON.QnAIntent` by following the steps at [Permissions for the AMAZON.QnAIntent](qna-permissions.md).

To take advantage of the `AMAZON.QnAIntent` you must have set up one of the following knowledge stores.
