Implementing Anthropic's Contextual Retrieval with Async Processing

Anthropic's Contextual Retrieval technique enhances RAG systems by preserving crucial context.

This post examines the method and demonstrates an efficient implementation using async processing. We'll explore how to optimize your RAG applications with this approach, building on concepts from our async processing guide.

Why should I use prompt caching?

Developers often face two key challenges when working with large context - Slow response times and high costs. This is especially true when we're making multiple of these calls over time, severely impacting the cost and latency of our applications. With Anthropic's new prompt caching feature, we can easily solve both of these issues.

Since the new feature is still in beta, we're going to wait for it to be generally avaliable before we integrate it into instructor. In the meantime, we've put together a quickstart guide on how to use the feature in your own applications.

Announcing Anthropic Support

A special shoutout to Shreya for her contributions to the anthropic support. As of now, all features are operational with the exception of streaming support.

For those eager to experiment, simply patch the client with ANTHROPIC_JSON, which will enable you to leverage the anthropic client for making requests.

pip install instructor[anthropic]

from pydantic import BaseModel
from typing import List
import anthropic
import instructor

# Patching the Anthropics client with the instructor for enhanced capabilities
anthropic_client = instructor.from_openai(
    create=anthropic.Anthropic().messages.create,
    mode=instructor.Mode.ANTHROPIC_JSON
)

class Properties(BaseModel):
    name: str
    value: str

class User(BaseModel):
    name: str
    age: int
    properties: List[Properties]

user_response = anthropic_client(
    model="claude-3-haiku-20240307",
    max_tokens=1024,
    max_retries=0,
    messages=[
        {
            "role": "user",
            "content": "Create a user for a model with a name, age, and properties.",
        }
    ],
    response_model=User,
)  # type: ignore

print(user_response.model_dump_json(indent=2))
"""
{
    "name": "John",
    "age": 25,
    "properties": [
        {
            "key": "favorite_color",
            "value": "blue"
        }
    ]
}

We're encountering challenges with deeply nested types and eagerly invite the community to test, provide feedback, and suggest necessary improvements as we enhance the anthropic client's support.
