The Microsoft Cognitive Toolkit (CNTK) is an open-source deep-learning toolkit that describes neural networks as directed computational graphs, supporting DNNs, CNNs, and RNNs/LSTMs with automatic differentiation and distributed multi-GPU/multi-server training. It is usable as a library from Python, C#, C++, and Java, or standalone via its BrainScript model description language.

Use cases

• train deep neural networks across multiple gpus and servers
• build cnn and rnn/lstm models in python
• embed a deep learning library in c++ or c# applications
• evaluate trained neural network models from java
• run distributed sgd training with automatic differentiation

When to choose

• you must maintain or extend an existing CNTK-based codebase
• you need a legacy deep-learning toolkit for 64-bit Windows or Linux

When to avoid

• starting any new deep-learning project - CNTK is no longer actively developed
• you want modern framework support, ecosystem, and community updates (use PyTorch or TensorFlow instead)
