Understanding Intelligent Prompt Routing
Amazon Bedrock’s Intelligent Prompt Routing is engineered to maximize the efficiency of LLMs by intelligently routing simpler prompts to more cost-effective models. This strategic approach not only enhances overall performance but also significantly reduces operational expenses. The system is equipped with default prompt routers for each model family, enabling immediate deployment with pre-defined configurations specifically tailored to foundational models. Users also have the flexibility to customize their own routers to align with unique and evolving requirements. The service currently supports several LLM families, including:
- Anthropic Claude Series: Haiku, 5 v1, Haiku 3.5, Sonnet 3.5 v2
- Llama Series: Llama 3.1 8b, 70b, 3.2 11b, 90B, and 3.3 70B
- Nova Series: Nova Pro and Nova lite
AWS has rigorously tested Amazon Bedrock’s Intelligent Prompt Routing using both proprietary and publicly accessible data. The evaluation focused on two critical metrics:
- Average Response Quality Gain under Cost Constraint (ARQGC): This standardized metric, ranging from 0 to 1, rigorously assesses the quality of the router under various cost constraints. A score of 0.5 indicates random routing, while 1 represents optimal routing.
- Cost Savings: This metric precisely quantifies the cost efficiency of using Intelligent Prompt Routing compared to exclusively using the most powerful model in a given series.
- Latency Advantages: Measured by the Average Time to First Token (TTFT), this metric highlights the speed enhancements achieved through Intelligent Prompt Routing.
The collected data provides valuable insights into how effectively Intelligent Prompt Routing balances response quality, cost efficiency, and latency.
Delving into Response Quality Difference
The Response Quality Difference metric is pivotal for measuring the variance in responses between a designated fallback model and other available models. A smaller value indicates a higher degree of similarity in the responses, while a larger value suggests more significant disparities. The selection of the fallback model is crucial, as it directly influences the overall performance and cost-effectiveness of the routing system.
For instance, if Anthropic’s Claude 3 Sonnet is designated as the fallback model and the Response Quality Difference is set to 10%, the router dynamically selects an LLM that provides a response quality within 10% of Claude 3 Sonnet’s benchmark. This ensures consistent quality while optimizing for cost.
Conversely, if a lower-cost model like Claude 3 Haiku is chosen as the fallback model, the router dynamically selects an LLM that improves the response quality by more than 10% compared to Claude 3 Haiku. In scenarios where Haiku is the fallback model, a Response Quality Difference of 10% is strategically configured to achieve an optimal balance between cost and quality, maximizing value and efficiency.
Practical Implementation and Demonstration
Amazon Bedrock’s Intelligent Prompt Routing is readily accessible through the AWS Management Console, empowering users to create custom routers or leverage pre-configured defaults with ease. To configure a prompt router, simply navigate to Prompt Routers within the Amazon Bedrock console and select “Configure prompt router.”
Once configured, the router can be seamlessly integrated into the Playground within the console for testing and refinement. For example, a 10K document from Amazon.com can be attached, and specific questions regarding sales costs can be posed to evaluate the router’s performance.
By selecting the “router metrics” icon, users can quickly determine which model ultimately processed the request. In cases involving complex questions, Amazon Bedrock’s Intelligent Prompt Routing intelligently directs the request to a more powerful model such as Claude 3.5 Sonnet V2, ensuring accurate and comprehensive responses.

Benchmarking and Performance Analysis
The benchmark tests conducted by AWS offer valuable insights into the performance of Intelligent Prompt Routing across different model series. The ARQGC metric effectively highlights the router’s ability to maintain high response quality while adhering to pre-defined cost constraints. The cost savings metric clearly demonstrates the economic benefits of using Intelligent Prompt Routing compared to relying solely on the most powerful models. The TTFT metric underscores the latency advantages, indicating faster response times for a wide variety of queries.
These benchmarks consistently demonstrate that Intelligent Prompt Routing can significantly reduce costs while maintaining high-quality responses and minimizing latency across various model series. Users are encouraged to experiment with different Response Quality Difference values during configuration to identify the optimal settings for their specific needs. By carefully analyzing the response quality, cost, and latency of the router on their development datasets, users can fine-tune the configuration to achieve the best possible balance, maximizing both performance and value.
Configuring Response Quality Difference: A Deep Dive
The Response Quality Difference (RQD) is a pivotal parameter in Amazon Bedrock’s Intelligent Prompt Routing, allowing users to precisely fine-tune the balance between response quality and cost efficiency. A lower RQD setting encourages the system to prioritize models that deliver responses closely aligned with the chosen fallback model, ensuring consistency and reliability. Conversely, a higher RQD allows the router to explore a wider range of models, potentially sacrificing some quality in exchange for cost savings or latency improvements.
The selection of the fallback model is critical, as it serves as the benchmark against which other models are evaluated. For scenarios demanding the highest level of accuracy and detail, selecting a top-tier model like Claude 3 Sonnet as the fallback ensures that the router only considers models capable of delivering comparable results. In situations where cost is a primary concern, a more economical model like Claude 3 Haiku can be used as the fallback, allowing the router to optimize for efficiency while still maintaining acceptable quality levels.
Consider a scenario where a financial institution is using LLMs to provide customer support. If the institution sets Claude 3 Sonnet as the fallback model with an RQD of 5%, the Intelligent Prompt Routing system will only direct queries to models that deliver responses within 5% of Claude 3 Sonnet’s quality. This ensures that customers receive consistently high-quality support, but it may come at a higher cost. If the institution instead sets Claude 3 Haiku as the fallback with an RQD of 15%, the system can explore a broader range of models, potentially reducing costs while still providing reasonably accurate responses.
The ability to dynamically adjust the RQD based on real-time performance metrics further enhances the adaptability of the Intelligent Prompt Routing system. By continuously monitoring response quality, cost, and latency, the router can automatically adjust the RQD to maintain the desired balance between these factors. This ensures that the system remains optimized even as workloads and model capabilities evolve over time, providing sustained efficiency and value.
Advanced Use Cases and Customization
Beyond the default configurations, Amazon Bedrock’s Intelligent Prompt Routing offers advanced customization options to cater to specific use cases. Users can define custom routing rules based on factors such as the complexity of the query, the sensitivity of the data, or the desired response time. This allows for granular control over how prompts are processed, ensuring that the most appropriate models are always used for each task.
For example, a healthcare provider might configure custom routing rules to ensure that sensitive patient data is always processed by models that comply with HIPAA regulations, safeguarding patient privacy and maintaining regulatory compliance. Similarly, a legal firm might prioritize models that are known for their accuracy and reliability when processing critical legal documents, ensuring the integrity and precision of legal proceedings.
The ability to integrate custom metrics into the Intelligent Prompt Routing system further enhances its adaptability. Users can define their own metrics to measure specific aspects of response quality, such as sentiment analysis, factual accuracy, or coherence. By incorporating these custom metrics into the routing rules, the system can optimize for the specific requirements of each application, delivering tailored and effective solutions.
