:::
LiteLLM Python SDK Usage
Quick Start
from litellm import rerank
import os
os.environ["COHERE_API_KEY"] = "sk-.."
query = "What is the capital of the United States?"
documents = [
"Carson City is the capital city of the American state of Nevada.",
"The Commonwealth of the Northern Mariana Islands is a group of islands in the Pacific Ocean. Its capital is Saipan.",
"Washington, D.C. is the capital of the United States.",
"Capital punishment has existed in the United States since before it was a country.",
]
response = rerank(
model="cohere/rerank-english-v3.0",
query=query,
documents=documents,
top_n=3,
)
print(response)
Async Usage
from litellm import arerank
import os, asyncio
os.environ["COHERE_API_KEY"] = "sk-.."
async def test_async_rerank():
query = "What is the capital of the United States?"
documents = [
"Carson City is the capital city of the American state of Nevada.",
"The Commonwealth of the Northern Mariana Islands is a group of islands in the Pacific Ocean. Its capital is Saipan.",
"Washington, D.C. is the capital of the United States.",
"Capital punishment has existed in the United States since before it was a country.",
]
response = await arerank(
model="cohere/rerank-english-v3.0",
query=query,
documents=documents,
top_n=3,
)
print(response)
asyncio.run(test_async_rerank())
