NVIDIA NeMo Framework
NVIDIA NeMo Framework is a framework maintained by NVIDIA311314. Its source code is public3 under the Apache License 2.0 (Megatron Bridge)7, the Apache License 2.0 (AutoModel)8, and the Apache License 2.0 (NeMo RL)9.
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

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
In the news
NVIDIA releases NeMo Speech 3.0, the first major release after the NeMo repository split
NVIDIA published NeMo Speech 3.0 on GitHub on August 7, 2026. The release notes call it the first major release after the repository was split and renamed to NVIDIA-NeMo/Speech, which now focuses on ASR, TTS, audio processing, speaker tasks and SpeechLM, while LLM, VLM, diffusion, export and evaluator collections have moved to separate repositories. The notes say the release's central focus is technical debt, including the removal of deprecated code and a migration to the uv package manager. They also list support for training SpeechLM models with NeMo Automodel and the training and evaluation modules behind Nemotron VoiceChat. USASI has not tested this release.
U.S. eligibility
Eligible · basis: U.S.-governed project
