Unlocking Innovation: AWS and Anthropic push the boundaries of generative AI together

Amazon Bedrock is the best place to build and scale generative AI applications with large language models (LLM) and other foundation models (FMs). It enables customers to leverage a variety of high-performing FMs, such as the Claude family of models by Anthropic, to build custom generative AI applications. Looking back to 2021, when Anthropic first started building on AWS, no one could have envisioned how transformative the Claude family of models would be. We have been making state-of-the-art generative AI models accessible and usable for businesses of all sizes through Amazon Bedrock. In just a few short months since Amazon Bedrock became generally available on September 28, 2023, more than 10K customers have been using it to deliver, and many of them are using Claude. Customers such as ADP, Broadridge, Cloudera, Dana-Farber Cancer Institute, Genesys, Genomics England, GoDaddy, Intuit, M1 Finance, Perplexity AI, Proto Hologram, Rocket Companies and more are using Anthropic’s Claude models on Amazon Bedrock to drive innovation in generative AI and to build transformative customer experiences. And today, we are announcing an exciting milestone with the next generation of Claude coming to Amazon Bedrock: Claude 3 Opus, Claude 3 Sonnet, and Claude 3 Haiku.

Introducing Anthropic’s Claude 3 models

Anthropic is unveiling its next generation of Claude with three advanced models optimized for different use cases. Haiku is the fastest and most cost-effective model on the market. It is a fast compact model for near-instant responsiveness. For the vast majority of workloads, Sonnet is 2x faster than Claude 2 and Claude 2.1 with higher levels of intelligence. It excels at intelligent tasks demanding rapid responses, like knowledge retrieval or sales automation. And it strikes the ideal balance between intelligence and speed – qualities especially critical for enterprise use cases. Opus is the most advanced, capable, state-of-the-art FM with deep reasoning, advanced math, and coding abilities, with top-level performance on highly complex tasks. It can navigate open-ended prompts, and novel scenarios with remarkable fluency, including task automation, hypothesis generation, and analysis of charts, graphs, and forecasts. And Sonnet is first available on Amazon Bedrock today. Current evaluations from Anthropic suggest that the Claude 3 model family outperforms comparable models in math word problem solving (MATH) and multilingual math (MGSM) benchmarks, critical benchmarks used today for LLMs.

  1. Vision capabilities – Claude 3 models have been trained to understand structured and unstructured data across different formats, not just language, but also images, charts, diagrams, and more. This lets businesses build generative AI applications integrating diverse multimedia sources and solving truly cross-domain problems. For instance, pharmaceutical companies can query drug research papers alongside protein structure diagrams to accelerate discovery. Media organizations can generate image captions or video scripts automatically.
  2. Best-in-class benchmarks – Claude 3 exceeds existing models on standardized evaluations such as math problems, programming exercises, and scientific reasoning. Customers can optimize domain specific experimental procedures in manufacturing, or audit financial reports based on contextual data, in an automated way and with high accuracy using AI-driven responses.

    Specifically, Opus outperforms its peers on most of the common evaluation benchmarks for AI systems, including undergraduate level expert knowledge (MMLU), graduate level expert reasoning (GPQA), basic mathematics (GSM8K), and more. It exhibits high levels of comprehension and fluency on complex tasks, leading the frontier of general intelligence.

  3. Reduced hallucination – Businesses require predictive, controllable outputs from AI systems directing automated processes or customer interactions. Claude 3 models mitigate hallucination through constitutional AI techniques that provide transparency into the model’s reasoning, as well as improve accuracy. Claude 3 Opus shows an estimated 2x gain in accuracy over Claude 2.1 on difficult open-ended questions, reducing the likelihood of faulty responses. As enterprise customers rely on Claude across industries like healthcare, finance, and legal research, reducing hallucinations is essential for safety and performance. The Claude 3 family sets a new standard for reliable generative AI output.

The Claude 3 model family caters to various needs, allowing customers to choose the model best suited for their specific use case, which is key to developing a successful prototype and later production systems that can deliver real impact—whether for a new product, feature or process that boosts the bottom line. Keeping customer needs top of mind, Anthropic and AWS are delivering where it matters most to organizations of all sizes:

  1. Improved performance – Claude 3 models are significantly faster for real-time interactions thanks to optimizations across hardware and software.
  2. Increased accuracy and reliability – Through massive scaling as well as new self-supervision techniques, expected gains of 2x in accuracy for complex questions over long contexts mean AI that’s even more helpful, safe, and honest.
  3. Simpler and secure customization – Customization capabilities, like retrieval-augmented generation (RAG), simplify training models on proprietary data and building applications backed by diverse data sources, so customers get AI tuned for their unique needs. In addition, proprietary data is never exposed to the public internet, never leaves the AWS network, is securely transferred through VPC, and is encrypted in transit and at rest.

And AWS and Anthropic are continuously reaffirming our commitment to advancing generative AI in a responsible manner. By constantly improving model capabilities committing to frameworks like Constitutional AI or the White House voluntary commitments on AI, we can accelerate the safe, ethical development, and deployment of this transformative technology.
