TurboPuffer RAG integration for Vision Agents with hybrid search

TurboPuffer RAG Plugin

Hybrid search RAG (Retrieval Augmented Generation) implementation using TurboPuffer for vector + BM25 full-text search, with Gemini for embeddings.

Features

• Hybrid Search: Combines vector (semantic) and BM25 (keyword) search for better retrieval quality
• Reciprocal Rank Fusion: Merges results from multiple search strategies
• Gemini Embeddings: Uses Google's Gemini embedding model for high-quality vectors
• Low-latency Queries: Supports cache warming for fast query responses
• Implements RAG Interface: Compatible with Vision Agents RAG base class

Installation

uv add "vision-agents[turbopuffer]"
# or directly
uv add vision-agents-plugins-turbopuffer

Usage

from vision_agents.plugins import turbopuffer

# Initialize RAG
rag = turbopuffer.TurboPufferRAG(namespace="my-knowledge")
await rag.add_directory("./knowledge")

# Hybrid search (default)
results = await rag.search("How does the chat API work?")

# Vector-only search
results = await rag.search("How does the chat API work?", mode="vector")

# BM25-only search
results = await rag.search("chat API pricing", mode="bm25")

# Or use convenience function
rag = await turbopuffer.create_rag(
    namespace="product-knowledge",
    knowledge_dir="./knowledge"
)
