            TensorFlow Lite uses TensorFlow models converted into a smaller, more efficient machine
            learning (ML) model format. You can use pre-trained models with TensorFlow Lite, modify
            existing models, or build your own TensorFlow models and then convert them to
            TensorFlow Lite format. TensorFlow Lite models can perform almost any task a regular
            TensorFlow model can do: object detection, natural language processing, pattern
            recognition, and more using a wide range of input data including images, video, audio,
            and text.

              Get models for TensorFlow Lite</h2>
            <p>
            You don't have to build a TensorFlow Lite model to start using machine learning on
            mobile or edge devices. Many already-built and optimized models are available for you to
            use right away in your application. You can start with using pre-trained models in
            TensorFlow Lite and move up to building custom models over time, as follows:
            </p>
            <ol>
            <li>Start developing machine learning features with already
            <a href="/lite/models/trained">trained models.</a></li>
            <li>Modify existing TensorFlow Lite models using tools such as
            <a href="/lite/models/modify/model_maker">Model Maker</a>.</li>
            <li>Build a
            <a href="/tutorials/customization/custom_training_walkthrough">
            custom model</a> with TensorFlow tools and then
            <a href="/lite/models/convert">convert</a> it to TensorFlow Lite.</li>
            </ol>

            <p>
            If you are trying to quickly implement features or utility tasks with machine
            learning, you should review the use cases supported by
            <a href="https://developers.google.com/ml-kit">ML Kit</a> before starting
            development with TensorFlow Lite. This development tool provides APIs you can call
            directly from mobile apps to complete common ML tasks such as barcode scanning and
            on-device translation. Using this method can help you get results fast. However, ML Kit
            has limited options for extending its capabilities. For more information,
            see the <a href="https://developers.google.com/ml-kit">ML Kit</a> developer
            documentation.

            <h2 class="tfo-landing-page-heading no-link">Building models for your app: Constraints
            </h2>
            <p>
            If building a custom model for your specific use case is your ultimate goal, you should
            start with developing and training a TensorFlow model or extending an existing one.
            Before you start your model development process, you should be aware of the constraints
            for TensorFlow Lite models and build your model with these constraints in mind:
            <ul>
            <li>Limited compute capabilities</li>
            <li>Size of models</li>
            <li>Size of data</li>
            <li>Supported TensorFlow operations</li>
            </ul>
            </p>
            <p>
            For more detail about each of these constraints, see
            <a href="./build#model_design_constraints">model design contraints</a> in the
            Model build overview.
            For more information about building effective, compatible, high performance models for
            TensorFlow Lite, see <a href="../performance/best_practices">
            Performance best practices</a>.
