SEATTLE — Amazon has introduced new functionalities within its Amazon Bedrock platform aimed at streamlining the assessment and enhancement process for generative AI applications, allowing for more efficient testing and quicker turnaround times. The company now offers a novel approach to AI tool evaluation by integrating large language models as evaluators in an automated system.
The new capabilities include RAG evaluation supported by Amazon Bedrock Knowledge Bases and an innovative LLM-as-a-judge feature within Amazon Bedrock Model Evaluation. Both tools are designed to provide robust insights into the functionality and performance of AI applications, speeding up the transition from development to production phases.
For businesses relying on AI, accuracy in the functionality of their tools is paramount. With the RAG evaluation feature, users can automatically assess knowledge bases using Retrieval Augmented Generation (RAG) applications. This evaluation helps in refining the generative AI capabilities, ensuring the responses generated by the AI are both accurate and valuable based on several quality metrics such as correctness and helpfulness.
Similarly, the LLM-as-a-judge feature offers a cost-effective alternative to traditional human evaluation processes. This tool uses machine learning models to perform detailed assessments of other models, providing evaluations simulating a high level of human-like scrutiny. By using models to judge other models, Amazon aims to significantly reduce the time and expenditure normally associated with these evaluations.
These new features support a variety of metrics, including helpfulness, correctness, and harmfulness, addressing multiple aspects of responsible AI practices. These automated evaluations generate scores that are normalized from 0 to 1 to aid in interpretation, and detailed natural language explanations of each score are provided for better understanding.
Practical applications of these tools reveal their robust capabilities. For instance, in using the Amazon Bedrock console, an evaluation can be initiated by selecting a specific knowledge base and evaluation model, such as Anthropic’s Claude 3.5 Sonnet. The evaluation process involves not only the retrieval of information but also the generation of responses, for a comprehensive assessment of AI’s performance.
Amazon ensures transparency in these evaluations by providing full rubrics and judge prompts in the documentation, enabling both technical and non-technical users to understand the evaluation parameters and results. This approach allows users to adjust configurations and adopt best practices based on the feedback given by the evaluation results.
The new service is available in preview across multiple AWS regions, including US East (N. Virginia), US West (Oregon), Asia Pacific (Mumbai, Sydney, Tokyo), and Europe (Frankfurt, Ireland, London), among others.
As the world of AI advances, Amazon continues to adapt, offering solutions that reduce barriers and enhance ease of use in AI applications. To explore these new features, users can access the Amazon Bedrock console and utilize available resources, including extensive documentation and community feedback systems. These tools promise not only to enhance the capabilities of AI models but also refine the development process ensuring quicker deployment and more reliable AI applications in a variety of use cases.
For further information or to provide feedback about these new advancements, participants and interested parties are encouraged to engage with Amazon through their community platforms.
