Amazon Bedrock

Choose from a range of leading FMs

Amazon Bedrock helps you rapidly adapt and take advantage of the latest generative AI innovations with easy access to a choice of high-performing FMs from leading AI companies like AI21 Labs, Anthropic, Cohere, Meta, Mistral AI, Stability AI, and Amazon.

The single-API access of Amazon Bedrock, regardless of the models you choose, gives you the flexibility to use different FMs and upgrade to the latest model versions with minimal code changes.

Privately adapt models with your data

Model customization helps you deliver differentiated and personalized user experiences. To customize models for specific tasks, you can privately fine-tune FMs using your own labeled datasets in just a few quick steps.

Amazon Bedrock supports fine-tuning for Cohere Command, Meta Llama 2, Amazon Titan Text Lite and Express, Amazon Titan Multimodal Embeddings, and Amazon Titan Image Generator. To adapt Amazon Titan Text models to your industry and domain, you can use continued pretraining with unlabeled data.

With fine-tuning and continued pretraining, Amazon Bedrock makes a separate copy of the base FM that is accessible only by you, and your data is not used to train the original base models.

Deliver more relevant FM responses with RAG

To equip the FM with up-to-date proprietary information, organizations use Retrieval Augmented Generation (RAG), a technique that involves fetching data from company data sources and enriching the prompt with that data to deliver more relevant and accurate responses.

Knowledge Bases for Amazon Bedrock is a fully managed RAG capability that allows you to customize FM responses with contextual and relevant company data. Knowledge Bases for Amazon Bedrock automates the complete RAG workflow, including ingestion, retrieval, prompt augmentation, and citations, removing the need for you to write custom code to integrate data sources and manage queries.
