Bedrock is setting a new standard in the industry, enabling the creation of sophisticated, AI-driven applications that can transform operations and drive innovation in various sectors.

Key Features and Benefits of Amazon Bedrock

Amazon Bedrock offers a plethora of features designed to empower developers and businesses in their journey to create generative AI applications. Let’s explore some of the key features that make Bedrock a cutting-edge platform:

Choice and Flexibility

Amazon Bedrock provides developers with an extensive selection of high-performing foundation models (FMs) to choose from. With just an API call, developers can access leading models, including AI21 Labs’ Jurassic, Anthropic’s Claude, Cohere’s Command and Embed, Meta’s Llama 2, Stability AI’s Stable Diffusion, and Amazon’s Titan models. This flexibility allows businesses to select the FM that best suits their specific use case and application requirements, ensuring optimal performance and cost-effectiveness.

Experimentation with FMs

Developers can easily experiment with different FMs using interactive playgrounds for various modalities, such as text, chat, and image. These playgrounds enable developers to assess the suitability of different models for their use cases, providing valuable insights into model performance.

Model Evaluation

Amazon Bedrock offers Model Evaluation, allowing users to employ both automatic and human evaluations to select FMs tailored to their specific use cases. Automatic model evaluation utilizes curated datasets and predefined metrics like accuracy, robustness, and toxicity. Users can set up human evaluation workflows for subjective metrics to assess factors such as relevance, style, and brand alignment. This capability ensures that businesses can choose models that align perfectly with their requirements.

Customization with Fine-Tuning

To adapt FMs for specific tasks, Amazon Bedrock offers fine-tuning, a technique that allows users to create private, customized models using their own data. By providing a few labeled examples in Amazon S3, the platform creates a fine-tuned model accessible exclusively to the user. Fine-tuning is available for various models, including Command, Llama 2, Titan Text Lite and Express, Titan Image Generator, and Titan Multimodal Embeddings. This customization ensures that generative AI applications are tailored precisely to the user’s needs and requirements.

Single API for Inference

Amazon Bedrock simplifies the development process by providing a single API for inference, regardless of the model chosen. This unified API approach allows developers to switch between different models from various providers with minimal code changes, keeping applications up-to-date with the latest model versions.

Guardrails for AI Safety

Guardrails for Amazon Bedrock introduce an additional layer of safety to generative AI applications. These guardrails evaluate user inputs and FM responses based on use-case-specific policies, ensuring responsible AI usage. They can be applied across multiple FMs, including fine-tuned models, and integrated with Agents for Bedrock to align applications with responsible AI policies. Guardrails can block undesirable topics and filter harmful content, enhancing user experience and safety.

Knowledge Bases for Contextual Information

Amazon Bedrock’s Knowledge Bases enable the inclusion of contextual information from private data sources, enhancing the accuracy and relevance of responses. This fully managed support for Retrieval Augmented Generation (RAG) streamlines the workflow from data ingestion to retrieval and prompt augmentation. Knowledge Bases seamlessly connect FMs and agents to data sources, allowing for the secure retrieval of relevant data and prompt augmentation, improving the user experience.

Security and Compliance

Amazon Bedrock prioritizes data security and privacy. It offers encryption in transit and at rest, along with control over encryption keys using AWS Key Management Service (AWS KMS). The platform ensures that users maintain control over their data, with no sharing of data with model providers for improved privacy. It also supports private connectivity through AWS PrivateLink, complying with common compliance standards, including ISO, SOC, CSA STAR Level 2, HIPAA eligibility, and GDPR compliance.

Governance and Auditability

Amazon Bedrock provides comprehensive monitoring and logging capabilities to support governance and audit requirements. Amazon CloudWatch tracks usage metrics and offers customized dashboards for audits. AWS CloudTrail monitors API activity, and data can be stored in Amazon S3 buckets or Amazon CloudWatch Logs. Automated abuse detection mechanisms help prevent potential misuse, enhancing security and compliance.

The Different Amazon Bedrock Models

Amazon Bedrock stands out for its diverse selection of foundation models (FMs), each tailored to excel in specific areas and applications.
