Amazon Bedrock model evaluation is now generally available

The Amazon Bedrock model evaluation capability that we previewed at AWS re:Invent 2023 is now generally available. This new capability helps you to incorporate Generative AI into your application by giving you the power to select the foundation model that gives you the best results for your particular use case. As my colleague Antje explained in her post (Evaluate, compare, and select the best foundation models for your use case in Amazon Bedrock): Model evaluations are critical at all stages of development. As a developer, you now have evaluation tools available for building generative artificial intelligence (AI) applications. You can start by experimenting with different models in the playground environment. To iterate faster, add automatic evaluations of the models. Then,…

Import custom models in Amazon Bedrock (preview)

With Amazon Bedrock, you have access to a choice of high-performing foundation models (FMs) from leading artificial intelligence (AI) companies that make it easier to build and scale generative AI applications. Some of these models provide publicly available weights that can be fine-tuned and customized for specific use cases. However, deploying customized FMs in a secure and scalable way is not an easy task. Starting today, Amazon Bedrock adds in preview the capability to import custom weights for supported model architectures (such as Meta Llama 2, Llama 3, and Mistral) and serve the custom model using On-Demand mode. You can import models with weights in Hugging Face safetensors format from Amazon SageMaker and Amazon Simple Storage Service (Amazon S3). In…

Amazon Titan Image Generator and watermark detection API are now available in Amazon Bedrock

During AWS re:Invent 2023, we announced the preview of Amazon Titan Image Generator, a generative artificial intelligence (generative AI) foundation model (FM) that you can use to quickly create and refine realistic, studio-quality images using English natural language prompts. I’m happy to share that Amazon Titan Image Generator is now generally available in Amazon Bedrock, giving you an easy way to build and scale generative AI applications with new image generation and image editing capabilities, including instant customization of images. In my previous post, I also mentioned that all images generated by Titan Image Generator contain an invisible watermark, by default, which is designed to help reduce the spread of misinformation by providing a mechanism to identify AI-generated images. I’m…

Unify DNS management using Amazon Route 53 Profiles with multiple VPCs and AWS accounts

If you are managing lots of accounts and Amazon Virtual Private Cloud (Amazon VPC) resources, sharing and then associating many DNS resources to each VPC can present a significant burden. You often hit limits around sharing and association, and you may have gone as far as building your own orchestration layers to propagate DNS configuration across your accounts and VPCs. Today, I’m happy to announce Amazon Route 53 Profiles, which provide the ability to unify management of DNS across all of your organization’s accounts and VPCs. Route 53 Profiles let you define a standard DNS configuration, including Route 53 private hosted zone (PHZ) associations, Resolver forwarding rules, and Route 53 Resolver DNS Firewall rule groups, and apply that configuration to…
