embedding

Overview

Most powerful OpenAI embedding model, with a larger embedding size. Great for vector search applications requiring higher degrees of accuracy.

Using the model

Installation:

!pip install -qU openai==1.2.2 pinecone

Create Index

from pinecone import Pinecone, ServerlessSpec

pc = Pinecone(api_key="API_KEY")

# Create Index
index_name = "text-embedding-3-large"

if not pc.has_index(index_name):
    pc.create_index(
        name=index_name,
        dimension=3074,
        metric="cosine",
        spec=ServerlessSpec(
            cloud='aws',
            region='us-east-1'
        )
    )

index = pc.Index(index_name)

Embed & Upsert

# Embed data
data = [
    {"id": "vec1", "text": "Apple is a popular fruit known for its sweetness and crisp texture."},
    {"id": "vec2", "text": "The tech company Apple is known for its innovative products like the iPhone."},
    {"id": "vec3", "text": "Many people enjoy eating apples as a healthy snack."},
    {"id": "vec4", "text": "Apple Inc. has revolutionized the tech industry with its sleek designs and user-friendly interfaces."},
    {"id": "vec5", "text": "An apple a day keeps the doctor away, as the saying goes."},
]

### Query
query = "Tell me about the tech company known as Apple"

x = embed([query])

results = index.query(

    top_k=3,
    include_values=False,
    include_metadata=True
)
