NVIDIA NeMo Framework
Project record
NeMo Framework is NVIDIA's open-source Python framework for pretraining, post-training, and reinforcement learning of generative AI models, organized as separate libraries in the NVIDIA-NeMo GitHub organization, including Megatron Bridge, AutoModel, NeMo RL, Curator, Evaluator, Export-Deploy, Run, and NeMo Speech. In 2026 the original NeMo repository was split and now focuses on audio, speech, and multimodal LLMs as NeMo Speech (version 3.0), and for the framework container from 26.02 onward NVIDIA points to Megatron Bridge's documentation and release notes.1342

Availability and license
Overall availability
Library source code is public on GitHub. The prebuilt NeMo Framework container on NVIDIA NGC is covered by the NVIDIA AI Product Agreement rather than Apache 2.0.32
Availability is separate from permission: read the license before using or redistributing.

The library repositories checked (Megatron Bridge, AutoModel, NeMo RL, Curator, Evaluator, and NeMo Speech) carry the Apache License 2.0; Curator's LICENSE file also includes an MIT License notice for Microsoft code. NVIDIA's user guide states that the NeMo Framework container is licensed under the NVIDIA AI Product Agreement, accepted by pulling and using it, and that it contains Llama materials governed by Meta's Llama 3 Community License Agreement.7891011122
Public materials checklist
| Item | Status | Notes and evidence |
|---|---|---|
| Source codeIs the source code publicly readable? | Public | Each library is developed in a public repository under github.com/NVIDIA-NeMo.3 |
| DocumentationIs user documentation published? | Public | Per-library documentation is published under docs.nvidia.com/nemo.12 |
| InstallationAre installation instructions or packages publicly available? | Public | NVIDIA recommends the NeMo Framework container from NGC for Megatron Bridge; libraries are also installable from PyPI (for example megatron-bridge and nemo-toolkit) or from source.541314 |
| Supported platformsAre supported operating systems or hardware documented? | Public | Requirements are documented per library. NeMo Speech requires Python 3.12 or later and PyTorch 2.7 or later, and needs an NVIDIA GPU with CUDA for training. The component versions page lists the CUDA, PyTorch, and Megatron Core versions in each framework container.46 |
| Release statusAre versioned releases published? | Public | NeMo Framework containers are versioned by year and month; the component versions page lists releases through 26.06. Individual libraries publish their own releases (for example NeMo Speech 3.0.0).64 |
What it is useful for
NVIDIA's documentation lists data curation (Curator), training and fine-tuning of large language, vision-language, and speech models (Megatron Bridge, AutoModel, NeMo Speech), post-training with reinforcement learning (NeMo RL), evaluation (Evaluator), and export and deployment to inference engines (Export-Deploy).15
Organization context
U.S. eligibility
Eligible · basis: U.S.-governed project
The libraries are published under the NVIDIA-NeMo GitHub organization, NVIDIA's documentation presents NeMo Framework as an NVIDIA software suite component, and the PyPI packages list NVIDIA as author. NVIDIA's principal executive offices are in Santa Clara, California, per its Form 10-Q for the quarter ended July 26, 2026.31131415
