Measure assistant response quality with LLM-based evaluation.
This page shows you how to evaluate responses from an assistant or other RAG systems using the metrics_alignment operation.
You can evaluate a response from an assistant, as in the following example:
# To use the Python SDK, install the plugin:
# pip install --upgrade pinecone pinecone-plugin-assistant
# pip install requests
import requests
from pinecone_plugins.assistant.models.chat import Message
payload = {
"question": "What are the capital cities of France, England and Spain?", # Question to ask the assistant.
"answer": "Paris is the capital city of France and Barcelona of Spain", # Answer from the assistant.
"ground_truth_answer": "Paris is the capital city of France, London of England and Madrid of Spain." # Expected answer to evaluate the assistant's response.
}

"Content-Type": "application/json"
}
url = "https://prod-1-data.ke.pinecone.io/assistant/evaluation/metrics/alignment"
response = requests.request("POST", url, json=payload, headers=headers)
print(response.text)PINECONE_API_KEY="YOUR_API_KEY"
