TensorFlow Lite Roadmap

Updated: April 18, 2020

The following represents a high level overview of our 2020 plan. You should be aware that this roadmap may change at any time and the order below does not reflect any type of priority. As a matter of principle, we typically prioritize issues based on the number of users affected.

We break our roadmap into four key segments: usability, performance, optimization and portability. We strongly encourage you to comment on our roadmap and provide us feedback in the TF Lite discussion group.


  • Expanded ops coverage
    • Prioritized op additions based on user feedback
  • Improvements to using TensorFlow ops in TensorFlow Lite
    • Pre-built libraries available via Bintray (Android) and Cocoapods (iOS)
    • Smaller binary size when using select TF ops via op stripping
  • LSTM / RNN support
    • Full LSTM and RNN conversion support, including support in Keras
  • Pre-and-post processing support libraries and codegen tool
    • Ready-to-use API building blocks for common ML tasks
    • Support more models (e.g. NLP) and more platforms (e.g. iOS)
  • Android Studio Integration
    • Drag & drop TFLite models into Android Studio to generate model binding classes
  • Control Flow & Training on-device
    • Support for training on-device, focused on personalization and transfer learning
  • Visualization tooling with TensorBoard
    • Provide enhanced tooling with TensorBoard
  • Model Maker
    • Support more tasks, including object detection and BERT-based NLP tasks
  • More models and examples
    • More examples to demonstrate model usage as well as new features and APIs, covering different platforms.
  • Task Library
    • Improve the usability of the C++ Task Library, such as providing prebuilt binaries and creating user-friendly workflows for users who want to build from source code.
    • Release reference examples of using the Task Library.
    • Enable more task types.
    • Improve cross-platform support and enable more tasks for iOS.
