Covering Disruptive Technology Powering Business in The Digital Age

Amazon Web Services, Inc. (AWS), an Amazon.com, Inc. company, has announced new Amazon Bedrock innovations that offer customers the easiest, fastest, and most secure way to develop advanced generative artificial intelligence (AI) applications and experiences.

Tens of thousands of customers have already selected Amazon Bedrock as the foundation for their generative AI strategy because it gives them access to the broadest selection of leading foundation models (FMs) from AI21 Labs, Anthropic, Cohere, Meta, Mistral AI, Stability AI, and Amazon, along with the capabilities and enterprise security they need to quickly build and deploy generative AI applications.

Amazon Bedrock’s powerful models are offered as a fully managed service so customers do not need to worry about the underlying infrastructure, ensuring their applications operate with seamless deployment, scalability, and continuous optimization. Today’s announcements empower customers to run their own fully managed models on Amazon Bedrock, make it simple to find the best model for their use case, make it easier to apply safeguards to generative AI applications, and provide them even more model choice.

Organisations across all industries, from the world’s fastest-growing startups to the most security-conscious enterprises and government institutions, are using Amazon Bedrock to spark innovation, increase productivity, and create new end-user experiences.

The New York Stock Exchange (NYSE), for example, is leveraging Amazon Bedrock’s choice of FMs and cutting-edge AI generative capabilities across several use cases, including the processing of thousands of pages of regulations to provide answers in easy-to-understand language. Ryanair, Europe’s largest airline, is using Amazon Bedrock to help its crew to instantly find answers to questions about country-specific regulations or extract summaries from manuals, to keep their passengers moving.

“Amazon Bedrock is experiencing explosive growth, with tens of thousands of organiaations of all sizes and across all industries choosing it as the foundation for their generative AI strategy because they can use it to move from experimentation to production more quickly and easily than anywhere else,” said Dr Swami Sivasubramanian, Vice President of AI and Data at AWS. “Customers are excited by Amazon Bedrock because it offers enterprise-grade security and privacy, wide choice of leading foundation models, and the easiest way to build generative AI applications. With today’s announcements, we continue to innovate rapidly for our customers by doubling down on our commitment to provide them with the most comprehensive set of capabilities and choice of industry-leading models, further democratizing generative AI innovation at scale.”

New Custom Model Import Capability Helps Organisations Bring Customised Models to Amazon Bedrock

In addition to having access to the world’s most powerful models on Amazon Bedrock–from AI21 Labs, Amazon, Anthropic, and Cohere, to Meta, Mistral AI, and Stability AI–customers across healthcare, financial services, and other industries are increasingly putting their own data to work by customising publicly available models for their domain-specific use cases.

When organisations want to build these models using their proprietary data, they typically turn to services like Amazon SageMaker, which offers the best-in-class training capabilities to train a model from scratch or perform advanced customization on publicly available models such as Llama, Mistral, and Flan-T5.

Since launching 2017, Amazon SageMaker has become the place where the world’s high-performing FMs–including Falcon 180, the largest publicly available model to date–are built and trained. Customers also want to use all of Amazon Bedrock’s advanced, built-in generative AI tools such as Knowledge Bases, Guardrails, Agents, and Model Evaluation, with their customized models, without having to develop all these capabilities themselves.

With Amazon Bedrock Custom Model Import, organisations can now import and access their own custom models as a fully managed application programming interface (API) in Amazon Bedrock, giving them unprecedented choice when building generative AI applications. With just a few clicks, customers can take models that they customised on Amazon SageMaker, or other tools, and easily add them to Amazon Bedrock.

Once through an automated validation process, they can seamlessly access their custom model, like any other on Amazon Bedrock, getting all the same benefits that they get today—including seamless scalability and powerful capabilities to safeguard their applications, adhering to responsible AI principles, the ability to expand a model’s knowledge base with retrieval augmented generation (RAG), easily creating agents to complete multi-step tasks, and carrying out fine-tuning to keep teaching and refining models–without needing to manage the underlying infrastructure.

With this new capability, AWS makes it easy for organizations to choose a combination of Amazon Bedrock models and their own custom models via the same API. Today, Amazon Bedrock Custom Model Import is available in preview and supports three of the most popular open model architectures, Flan-T5, Llama, and Mistral—and with plans for more in the future.

Model Evaluation Helps Customers Assess, Compare, and Select the Best Model for Their Application

With the broadest range of industry-leading models, Amazon Bedrock helps organisations meet any price, performance, or capability requirements they may have and allows them to run models on their own or in combination with others.

However, choosing the best model for a specific use case requires customers to strike a delicate balance between accuracy and performance. Until now, organisations needed to spend countless hours analyzing how every new model can meet their use case, limiting how quickly they could deliver transformative generative AI experiences to their end users.

Now generally available, Model Evaluation is the fastest way for organisations to analyse and compare models on Amazon Bedrock, reducing time from weeks to hours spent evaluating models so they can bring new applications and experiences to market faster.

Customers can get started quickly by selecting predefined evaluation criteria (e.g., accuracy and robustness) and uploading their own dataset or prompt library, or by selecting from built-in, publicly available resources.

For subjective criteria or content requiring nuanced judgment, Amazon Bedrock makes it easy for customers to add humans into the workflow to evaluate model responses based on use case-specific metrics (e.g., relevance, style, and brand voice). Once the setup process is finished, Amazon Bedrock runs evaluations and generates a report so customers can easily understand how the model performed across their key criteria and quickly select the best models for their use cases.

With Guardrails for Amazon Bedrock, Customers Can Deploy Best-in-Class Safeguards

For generative AI to be pervasive across every industry, organisations need to implement it in a safe, trustworthy, and responsible way. Many models use built-in controls to filter undesirable and harmful content, but most customers want to further tailor their generative AI applications so responses remain relevant, align with company policies, and adhere to responsible AI principles.

Now generally available, Guardrails for Amazon Bedrock offers industry-leading safety protection on top of the native capabilities of FMs, helping customers block up to 85% of harmful content. Guardrails is the only solution offered by a top cloud provider that allows customers to have built-in and custom safeguards in a single offering, and it works with all large language models (LLMs) in Amazon Bedrock, as well as fine-tuned models.

To create a guardrail, customers simply provide a natural-language description defining the denied topics within the context of their application. Customers can also configure thresholds to filter across areas like hate speech, insults, sexualized language, prompt injection, and violence, as well as filters to remove any personal and sensitive information, profanity, or specific blocked words.

Guardrails for Amazon Bedrock empowers customers to innovate quickly and safely by providing a consistent user experience and standardising safety and privacy controls across generative AI applications.

More Model Choice: Introducing Amazon Titan Text Embeddings V2 and More

Exclusive to Amazon Bedrock, Amazon Titan models are created and pre-trained by AWS on large and diverse datasets for a variety of use cases, with built-in support for the responsible use of AI.

Today, Amazon Bedrock continues to grow the Amazon Titan family, giving customers even greater choice and flexibility. Amazon Titan Text Embeddings V2, which is optimised for working with RAG use cases, is well suited for a variety of tasks such as information retrieval, question-and-answer chatbots, and personalised recommendations.

To augment FM responses with additional data, many organisations turn to RAG, a popular model-customisation technique where the FM connects to a knowledge source that it can reference to augment its responses.

However, running these operations can be compute and storage intensive. The new Amazon Titan Text Embeddings V2 model, launching next week, reduces storage and compute costs, all while increasing accuracy. It does so by allowing flexible embeddings to customers, which reduces overall storage up to 4x, significantly reducing operational costs, while retaining 97% of the accuracy for RAG use cases, outperforming other leading models.

Now generally available, Amazon Titan Image Generator helps customers in industries like advertising, ecommerce, and media and entertainment produce studio-quality images or enhance and edit existing images, at low cost, using natural language prompts.

Amazon Titan Image Generator also applies an invisible watermark to all images it creates, helping identify AI-generated images to promote the safe, secure, and transparent development of AI technology and helping reduce the spread of disinformation. The model can also check for the existence of watermark, helping customers confirm whether an image was generated by Amazon Titan Image Generator.

Also available today on Amazon Bedrock are Meta Llama 3 FMs and coming soon are the Command R and Command R+ models from Cohere. Llama 3 is designed for developers, researchers, and businesses to build, experiment, and responsibly scale their generative AI ideas.

The Llama 3 models are a collection of pre-trained and instruction fine-tuned LLMs that support a broad range of use cases. They are particularly suited for text summarization and classification, sentiment analysis, language translation, and code generation. Cohere’s Command R, and Command R+ models are state-of-the-art FMs customers can use to build enterprise-grade generative AI applications with advanced RAG capabilities, in 10 languages, to support their global business operations.
