<a name="using-nova-capabilities"></a>

This guide provides task-based recipes and practical examples to help you integrate Nova's capabilities into your applications quickly and effectively. It is designed for developers and engineers who want to:
+ Integrate Nova models into their applications via API
+ Understand preprocessing requirements and optimization strategies
+ Implement multimodal understanding workflows

Each section provides:
+ Key technical information about supported formats, size limits, and token estimation
+ Code examples that demonstrate how to use API with both direct upload and Amazon S3
+ Use cases that show practical applications
+ Limitations to consider when designing your application

**Prerequisites**

Before you begin, ensure you have:
+ An AWS account with access to Amazon Bedrock
+ Appropriate IAM permissions for invoking Bedrock models
+ AWS SDK installed (Boto3 for Python examples)
+ Basic familiarity with AWS services, such as Amazon S3 (for large file handling)
