Megatron

TECHNICAL DEFINITION

Megatron is a framework developed by NVIDIA for training extremely large transformer language models, focusing on efficient distributed training techniques like data, tensor, and pipeline parallelism to scale models with billions or trillions of parameters.

BACKGROUND

A large language model (LLM) is a neural network trained on a vast amount of text for natural language processing tasks, especially language generation. LLMs can typically generate, summarize, translate and analyze text in many contexts, and are a foundational technology behind modern chatbots. Biased or inaccurate training data can make an LLM's output less reliable.
