## What it is
Brainstorm is a Python neural network library designed to be fast, flexible, and fun, supporting multiple computing backends. The project has been officially discontinued, with maintainers recommending TensorFlow or Chainer instead.

## Use cases
- build and train neural networks in Python
- train deep learning models with multiple backends
- experiment with network architectures
- GPU-accelerated neural network training

## When to choose
- studying the design of an older lightweight neural network framework
- maintaining legacy code that already depends on brainstorm

## When to avoid
- starting any new deep learning project
- needing active maintenance, community support, or modern features
- requiring state-of-the-art performance

## Facets
- artifact type: framework
- maturity: abandoned
- function: deep-learning, machine-learning
- domain: deep-learning, machine-learning
- platform: python, cross-platform
- tags: neural-networks, discontinued, gpu
