## What it is
NeuronBlocks is an NLP deep learning modeling toolkit from Microsoft that lets users build end-to-end neural network training and inference pipelines for NLP tasks using composable blocks and JSON configuration files. It includes a Block Zoo of reusable neural components and a Model Zoo of prebuilt models for tasks like classification, sequence labeling, and question answering matching.

## Use cases
- build nlp deep learning models without writing code
- train a text classifier with  config
- do sequence labeling like slot tagging
- train a question answering matching model
- compress models via knowledge distillation
- prototype neural architectures from reusable blocks

## When to choose
- you want config-driven NLP model training in PyTorch
- you need prebuilt models for common NLP tasks like classification or slot tagging
- you want to experiment with model architectures by composing blocks

## When to avoid
- you need state-of-the-art transformer fine-tuning with modern ecosystems like Hugging Face
- you require active community support or frequent updates
- you work outside NLP or need non-PyTorch frameworks

## Facets
- artifact type: framework
- maturity: maintenance
- function: machine-learning, deep-learning, nlp, llm-training
- domain: deep-learning, machine-learning
- platform: python, windows, cross-platform
