🏗️ How They Work

🔍 FAISS Architecture

FAISS is a library that runs within your application. It builds efficient index structures in memory or on disk for fast similarity search.

import faiss
import numpy as np

# Create index for 1024-dim vectors
index = faiss.IndexFlatIP(1024)

# Add vectors
vectors = np.random.random((1000, 1024))
index.add(vectors.astype('float32'))

# Search
query = np.random.random((1, 1024))
distances, indices = index.search(
    query.astype('float32'), k=10
)

🌲 Pinecone Architecture

Pinecone is a managed service accessed via REST API. Your data is stored and indexed in Pinecone's cloud infrastructure.

import pinecone

# Initialize Pinecone
pinecone.init(api_key="your-key")

# Create index
index = pinecone.Index("imagebind-index")

# Upsert vectors
index.upsert([
    ("id1", [0.1, 0.2, ...], {"text": "dog"}),
    ("id2", [0.3, 0.4, ...], {"text": "cat"})
])

# Search
results = index.query(
    vector=[0.1, 0.2, ...], 
    top_k=10, 
    include_metadata=True
)
