NVIDIA NeMo Framework Developer Docs
====================================

NVIDIA NeMo Framework is an end-to-end, cloud-native framework designed to build, customize, and deploy generative AI models anywhere.

`NVIDIA NeMo Framework <https://github.com/NVIDIA/NeMo>`_ supports large-scale training features, including:

- Mixed Precision Training
- Parallelism
- Distributed Optimizer
- Fully Sharded Data Parallel (FSDP)
- Flash Attention
- Activation Recomputation
- Positional Embeddings and Positional Interpolation
- Post-Training Quantization (PTQ) and Quantization Aware Training (QAT) with `TensorRT Model Optimizer <https://github.com/NVIDIA/TensorRT-Model-Optimizer>`_
- Knowledge Distillation-based training with `TensorRT Model Optimizer <https://github.com/NVIDIA/TensorRT-Model-Optimizer>`_
- Sequence Packing

`NVIDIA NeMo Framework <https://github.com/NVIDIA/NeMo>`_ has separate collections for:

* :doc:`Large Language Models (LLMs) <nlp/nemo_megatron/intro>`

* :doc:`Automatic Speech Recognition (ASR) <asr/intro>`

* :doc:`Text-to-Speech (TTS) <tts/intro>`

Each collection consists of prebuilt modules that include everything needed to train on your data.
Every module can easily be customized, extended, and composed to create new generative AI
model architectures.
