OpenLLM

OpenLLM helps developers run any open-source LLMs, such as Llama 2 and Mistral, as OpenAI-compatible API endpoints, locally and in the cloud, optimized for serving throughput and production deployment.

Install

Recommend using a Python Virtual Environment

pip install openllm

Start a LLM Server

openllm start microsoft/Phi-3-mini-4k-instruct --trust-remote-code

To interact with the server, you can visit the web UI at http://localhost:3000/ or send a request using curl. You can also use OpenLLM’s built-in Python client to interact with the server:

import openllm

client = openllm.HTTPClient('http://localhost:3000')
client.generate('Explain to me the difference between "further" and "farther"')

OpenAI Compatible Endpoints

import openai

client = openai.OpenAI(base_url='http://localhost:3000/v1', api_key='na')  # Here the server is running on 0.0.0.0:3000

completions = client.chat.completions.create(
  prompt='Write me a tag line for an ice cream shop.', model=model, max_tokens=64, stream=stream
)

LangChain

from langchain.llms import OpenLLMAPI

llm = OpenLLMAPI(server_url='http://44.23.123.1:3000')
llm.invoke('What is the difference between a duck and a goose? And why there are so many Goose in Canada?')

# streaming
for it in llm.stream('What is the difference between a duck and a goose? And why there are so many Goose in Canada?'):
  print(it, flush=True, end='')

# async context
await llm.ainvoke('What is the difference between a duck and a goose? And why there are so many Goose in Canada?')

# async streaming
async for it in llm.astream('What is the difference between a duck and a goose? And why there are so many Goose in Canada?'):
  print(it, flush=True, end='')
