Quick Start

LiteLLM Python SDK

Example using LiteLLM Python SDK

import os
import litellm

from litellm.vector_stores.vector_store_registry import VectorStoreRegistry, LiteLLM_ManagedVectorStore

# Init vector store registry with your Bedrock Knowledge Base
litellm.vector_store_registry = VectorStoreRegistry(
    vector_stores=[
        LiteLLM_ManagedVectorStore(
            vector_store_id="YOUR_KNOWLEDGE_BASE_ID",  # KB ID from AWS Bedrock
            custom_llm_provider="bedrock"
        )
    ]
)

# Make a completion request using your Knowledge Base
response = await litellm.acompletion(
    model="anthropic/claude-3-5-sonnet", 
    messages=[{"role": "user", "content": "What does our company policy say about remote work?"}],
    tools=[
        {
            "type": "file_search",
            "vector_store_ids": ["YOUR_KNOWLEDGE_BASE_ID"]
        }
    ],
)

print(response.choices[0].message.content)

LiteLLM Proxy

1. Configure your vector_store_registry

config.yaml

model_list:
  - model_name: claude-3-5-sonnet
    litellm_params:
      model: anthropic/claude-3-5-sonnet
      api_key: os.environ/ANTHROPIC_API_KEY

vector_store_registry:
  - vector_store_name: "bedrock-company-docs"
    litellm_params:
      vector_store_id: "YOUR_KNOWLEDGE_BASE_ID"
      custom_llm_provider: "bedrock"
      vector_store_description: "Bedrock Knowledge Base for company documents"
      vector_store_metadata:
        source: "Company internal documentation"

LiteLLM UI

On the LiteLLM UI, Navigate to Experimental > Vector Stores > Create Vector Store. On this page you can create a vector store with a name, vector store id and credentials.

2. Make a request with vector_store_ids parameter

Curl

curl http://localhost:4000/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $LITELLM_API_KEY" \
  -d '{
    "model": "claude-3-5-sonnet",
    "messages": [{"role": "user", "content": "What does our company policy say about remote work?"}],
    "tools": [
        {
            "type": "file_search",
            "vector_store_ids": ["YOUR_KNOWLEDGE_BASE_ID"]
        }
    ]
  }'

OpenAI Python SDK

from openai import OpenAI

# Initialize client with your LiteLLM proxy URL
client = OpenAI(
    base_url="http://localhost:4000",
    api_key="your-litellm-api-key"
)

# Make a completion request with vector_store_ids parameter
response = client.chat.completions.create(
    model="claude-3-5-sonnet",
    messages=[{"role": "user", "content": "What does our company policy say about remote work?"}],
    tools=[
        {
            "type": "file_search",
            "vector_store_ids": ["YOUR_KNOWLEDGE_BASE_ID"]
        }
    ]
)

print(response.choices[0].message.content)
