TensorFlow

TensorFlow is an open-source machine learning platform developed by Google that supports the full lifecycle of building, training, and deploying models across servers, mobile devices, browsers, and edge hardware.

TensorFlow is an open-source machine learning platform developed by the Google Brain team and released publicly in 2015. It was one of the first widely adopted deep-learning frameworks and is designed to span the entire model lifecycle, from research experimentation to large-scale production deployment across data centres, mobile phones, web browsers, and embedded devices.

The name refers to the flow of tensors, multi-dimensional arrays, through a computational graph of mathematical operations. In its original design, TensorFlow used a static graph that was defined in full before execution, which enabled aggressive optimisation but made debugging harder. With TensorFlow 2.0, released in 2019, the platform adopted eager execution by default, bringing it closer to the interactive, line-by-line style popularised by PyTorch, while retaining the option to compile graphs for performance.

Keras and the high-level API

Since TensorFlow 2.0, the recommended way to build models is through Keras, a high-level API that is now tightly integrated as tf.keras. Keras lets developers assemble networks from layers using concise, readable code, define training with a few method calls, and switch between simple sequential models and complex custom architectures. This integration significantly improved TensorFlow's ease of use, which had been a common criticism of earlier versions.

Deployment ecosystem

TensorFlow's principal advantage is its mature deployment tooling. TensorFlow Serving provides a high-performance system for hosting models behind an API in production. TensorFlow Lite (now part of the LiteRT effort) compresses and optimises models to run on Android, iOS, microcontrollers, and other resource-constrained hardware, supporting on-device and edge inference. TensorFlow.js enables models to run directly in a web browser using JavaScript. TFX, or TensorFlow Extended, offers an end-to-end pipeline framework covering data validation, training, evaluation, and serving for managed machine-learning operations.

The platform runs on central processing units, GPUs, and Google's custom Tensor Processing Units, which are designed specifically to accelerate TensorFlow workloads.

Position in 2025 and 2026

The framework landscape has consolidated into two leaders. As of 2025, TensorFlow retained roughly 38 percent of overall framework usage and a strong position in large-scale enterprise deployment, while PyTorch led research and new model development. TensorFlow and PyTorch have converged in their core capabilities, and the practical decision between them now rests on existing infrastructure, deployment targets, and team familiarity. Google has continued to invest in its newer JAX stack for cutting-edge model training, while maintaining TensorFlow for its broad production install base.
