What is NVIDIA NeMo Megatron?

NVIDIA NeMo Megatron, part of the NVIDIA AI platform, offers an easy, efficient, and cost-effective containerized framework to build and deploy LLMs. Designed for enterprise application development, it builds upon the most advanced technologies from NVIDIA research and provides an end-to-end workflow for automated distributed data processing, training large-scale customized GPT-3, T5, and multilingual T5 (mT5) models, and deploying models for inference at scale.

Harnessing the power of LLMs is made easy through validated and converged recipes with predefined configurations for training and inference. Customizing models is simplified by the hyperparameter tool, which automatically searches for the best hyperparameter configurations and performance for training and inference on any given distributed GPU cluster configuration. NeMo Megatron also allows for efficiently adapting models for different use cases using prompt-based learning capabilities, such as p-tuning and prompt tuning. These methods are more efficient than traditional fine-tuning and allow LLMs to adapt to new use cases without fine-tuning the full pretrained models.

Key product features.

SOTA training techniques.

NeMo Megatron delivers high training efficiency, making large-scale natural language processing (NLP) practical, using parallelism techniques such as:

  • Tensor parallelism to scale models within nodes
  • Data and pipeline parallelism to scale data and models across thousands of GPUs
  • Sequence parallelism to distribute activation memory across tensor parallel devices

Alongside tensor parallelism, selective activation recomputing optimizes recomputation and memory usage across tensor parallel devices during backpropagation.

It also comes equipped with fine-tuning capabilities, alongside prompt-based learning techniques, that enable customization for different datasets with minimal data, vastly improving performance and few-shot tasks.

Easy-to-use recipes and tools.

NeMo Megatron includes prepackaged scripts, reference examples, and documentation across the entire pipeline, making LLMs possible from day one.

Several validated and converged recipes for various model sizes, for GPT-3 and T5/mT5 architectures, allow for easy training and deployment of LLMs.

Custom LLMs are also made easy through a unique offering from NeMo Megatron—the hyperparameter tool, which automatically searches for the best hyperparameter configurations to optimize training and inference for any given multi-GPU configuration, training, or deployment constraints.


Experience large language models using NVIDIA NeMo LLM service.

The promise of LLMs serving several use cases with a single model can enable enterprises to develop a plethora of applications, ranging from content generation to text summarization to chatbots. Yet, using customized LLMs isn’t for the faint of heart, requiring immense amounts of compute resources and technical expertise.

NVIDIA NeMo LLM Service running on the NVIDIA AI platform provides the fastest path to customizing and using LLMs for AI applications. Developers can run them in private and public clouds, run them through an API, or experiment via a playground. Models can be trained from any framework or run out of the box. State-of-the-art prompt learning capabilities, which are compute-efficient techniques, embed context in user queries to allow for greater accuracy in specific use cases.
