TensorFlow is an end-to-end open-source machine learning platform developed by the Google Brain team. It provides a flexible ecosystem of libraries, runtimes, and tooling—including the high-level Keras API, graph and eager execution modes, TensorBoard for visualization, TensorFlow Extended (TFX) for production pipelines, TensorFlow Lite for on-device inference, and TensorFlow.js for browser and Node.js deployment. TensorFlow supports distributed training on CPUs, GPUs, and TPUs, model optimization (quantization, pruning), and model export/serving for production environments. Its unique value is the breadth of a production-ready ecosystem that covers research prototyping through large-scale deployment across cloud, edge, and browser environments backed by a large community and extensive third-party integrations.
