What is Keras and why is it used in deep learning?
Updated May 16, 2026
Short answer
Keras is a high-level neural networks API used for building and training deep learning models easily.
Deep explanation
Keras provides an abstraction over backend engines like TensorFlow, simplifying model creation through intuitive APIs. It supports fast prototyping and modular design.
Real-world example
Used in image classification apps, NLP systems, and recommendation engines.
Common mistakes
- Assuming Keras is a standalone framework rather than part of TensorFlow ecosystem.
Follow-up questions
- Is Keras slower than raw TensorFlow?
- What backends does Keras support?
