What it was for
TensorFlow (`tf.keras`, computational graphs, TPU support) replaced Google's internal DistBelief stack and became the default ML toolkit for researchers and production teams. It powers recommendation, vision, and NLPNatural language processing — software that understands, generates, or translates human language. systems — though PyTorch later challenged it in research.

Why it's here
TensorFlow democratized Google's production ML infrastructure for the wider community.
Why it mattered
It standardized how teams build, train, and deploy deep learningNeural networks with many layers that learn hierarchical representations from data. models.
What it solved
Researchers lacked portable tools matching the scale and reliability of hyperscaler ML systems.
