Large Language Model
A foundation model trained on huge text corpora to understand and generate language.
Large language models are deep neural networks built on the transformer architecture, trained on vast text corpora to learn statistical patterns across words and documents. This lets them handle many language tasks — summarization, translation, question answering, and code generation — without task-specific retraining. On AWS, Amazon Bedrock provides managed access to leading LLMs such as Anthropic Claude, Meta Llama, and Amazon Nova. The key exam distinction: all LLMs are foundation models, but not all foundation models are LLMs — image generators like Stability AI’s Stable Diffusion are also on Bedrock yet are not LLMs.
