Welcome to the Pulze.ai KNN Router

The KNN Router is an open-sourced intent-tuned LLM router designed to efficiently select the best language model (LLM) for a user’s query. This documentation provides an overview of how to deploy and utilize the KNN Router, as well as insights into its underlying technology.

​
Key Features of KNN Router

  1. Semantic Query Routing:
    • The KNN Router uses k-nearest neighbors (KNN) to find semantically similar queries, allowing for precise model selection based on user input.
  2. Weighted Scoring:
    • Each LLM associated with the nearest neighbors is scored based on a weighted average of distances, ensuring the most appropriate model is selected for each query.
  3. Minimal Latency:
    • Built in Go, the KNN Router is optimized for low-latency responses, making it suitable for real-time applications.
  4. Integration Flexibility:
    • The router can be integrated with various systems, including information retrieval systems, agents, and other LLMs.
  5. Open Source:
    • Being open-sourced, the KNN Router is available for customization and enhancement by the community.

Getting Started with KNN Router

​
Local Deployment

To deploy the KNN Router locally, follow these steps:
  1. Fetch Artifacts from Huggingface: 
    huggingface-cli download pulze/intent-v0.1 --local-dir .dist --local-dir-use-symlinks=False
  2. Start the Services: 
    docker compose up -d --build
  3. Query the Router: Use curl to send a query: 
    curl -s 127.0.0.1:8888/ \
    -X POST \
    -d '{"query":"give me instructions for making ramen at home"}' \
    -H 'Content-Type: application/json' | jq .
The expected output will include a ranked list of hits and scores for each target, similar to the following: 
{
  "hits": [ ... ],
  "scores": [ ... ]
}

​
Kubernetes Deployment

For Kubernetes deployment, refer to the provided example configuration.

​
Generating Deployment Artifacts

Before deploying, you need to generate the required artifacts:
  1. Prepare Input Files:
  • points.jsonl: Contains points and their respective categories and embeddings.
  • targets.jsonl: Contains targets and their respective scores for each point.
  1. Generate Artifacts: Use the following script to generate the required artifacts: 
    scripts/gen-artifacts.sh --points-data-path points.jsonl --scores-data-path targets.jsonl --output-dir ./dist
