DeepSpeed vs Keras: What are the differences?
# Introduction
Key differences between DeepSpeed and Keras:
1. **Framework Type**: DeepSpeed is a deep learning optimization library, specifically designed for large-scale distributed training, while Keras is a high-level neural networks API that can run on top of other deep learning frameworks like TensorFlow and Theano.
2. **Model Parallelism Support**: DeepSpeed provides native support for model parallelism, allowing for efficient training of models with large numbers of parameters across multiple GPUs, whereas Keras focuses more on ease of use and rapid prototyping for smaller models on a single GPU.
3. **Optimization Techniques**: DeepSpeed offers advanced optimization techniques like ZeRO-Offload, which significantly reduces memory usage during training by offloading optimizer states, enabling the training of larger models, whereas Keras provides a simplified interface for common optimization algorithms but may lack some of the more cutting-edge optimization methods.
4. **Training Efficiency**: DeepSpeed is known for its ability to scale training to thousands of GPUs efficiently, making it suitable for training very large models on massive datasets, while Keras is better suited for smaller-scale projects or research prototyping where quick iteration and model development are the primary focus.
5. **Community Support**: Keras benefits from being a widely-used and well-supported framework, with a large community of developers and resources available for troubleshooting and learning, whereas DeepSpeed, being a more specialized library, may have a smaller but highly focused user base and community support.
6. **Integration with Existing Frameworks**: Keras seamlessly integrates with TensorFlow, allowing users to take advantage of both the high-level API and the lower-level functionalities of TensorFlow, while DeepSpeed offers more limited integration options with other frameworks, primarily focusing on enhancing the capabilities of PyTorch for large-scale distributed training.
In summary, DeepSpeed is specialized for large-scale distributed training with advanced optimization techniques and model parallelism support, while Keras is a high-level API focused on ease of use and rapid prototyping for smaller-scale projects.

What is DeepSpeed?
It is a deep learning optimization library that makes distributed training easy, efficient, and effective. It can train DL models with over a hundred billion parameters on the current generation of GPU clusters while achieving over 5x in system performance compared to the state-of-art. Early adopters of DeepSpeed have already produced a language model (LM) with over 17B parameters called Turing-NLG, establishing a new SOTA in the LM category.
What is Keras?
Deep Learning library for Python. Convnets, recurrent neural networks, and more. Runs on TensorFlow or Theano. https://keras.io/

What are some alternatives to DeepSpeed and Keras?
TensorFlow
TensorFlow is an open source software library for numerical computation using data flow graphs. Nodes in the graph represent mathematical operations, while the graph edges represent the multidimensional data arrays (tensors) communicated between them. The flexible architecture allows you to deploy computation to one or more CPUs or GPUs in a desktop, server, or mobile device with a single API.
PyTorch
PyTorch is not a Python binding into a monolothic C++ framework. It is built to be deeply integrated into Python. You can use it naturally like you would use numpy / scipy / scikit-learn etc.
scikit-learn
scikit-learn is a Python module for machine learning built on top of SciPy and distributed under the 3-Clause BSD license.
CUDA
A parallel computing platform and application programming interface model,it enables developers to speed up compute-intensive applications by harnessing the power of GPUs for the parallelizable part of the computation.
Streamlit
It is the app framework specifically for Machine Learning and Data Science teams. You can rapidly build the tools you need. Build apps in a dozen lines of Python with a simple API.
