When you deploy your model with\nFirebase, Firebase ML only downloads the model when it's needed and\nautomatically updates your users with the latest version.\n\n\u003cbr /\u003e\n\nReady to get started?

This API might be changed in backward-incompatible ways and is not subject to any SLA or deprecation policy.\n\nKey capabilities\n----------------\n\n|----------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| TensorFlow Lite model deployment | Deploy your models using Firebase to reduce your app's binary size and to make sure your app is always using the most recent version available of your model |\n| On-device ML inference | Perform inference in an Apple or Android app using the TensorFlow Lite interpreter with your model. |\n| Automatic model updates | Configure the conditions under which your app automatically downloads new versions of your model: when the user's device is idle, is charging, or has a Wi-Fi connection |\n\nImplementation path\n-------------------\n\n|---|---------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| | **Train your TensorFlow model** | Build and train a custom model using TensorFlow. Or, re-train an existing model that solves a problem similar to what you want to achieve. |\n| | **Convert the model to TensorFlow Lite** | Convert your model from HDF5 or frozen graph format to TensorFlow Lite using the [TensorFlow Lite converter](https://www.tensorflow.org/lite/convert). |\n| | **Deploy your TensorFlow Lite model to Firebase** | Optional: When you deploy your TensorFlow Lite model to Firebase and include the Firebase ML SDK in your app, Firebase ML keeps your users up to date with the latest version of your model. You can configure it to automatically download model updates when the user's device is idle or charging, or has a Wi-Fi connection. |\n| | **Use the TensorFlow Lite model for inference** | Use the TensorFlow Lite interpreter in your Apple or Android app to perform inference with models deployed using Firebase. |\n\nCodelabs\n--------\n\nTry some [codelabs](/docs/ml/codelabs) to learn hands-on how Firebase can help you use\nTensorFlow Lite models more easily and effectively."]]
