A FastAPI framework to build production-grade LLM applications.

🚀 Features

• 🌐 multi-mode token streaming
• 💬 Gradio plugin for fast prototyping
• 🔗 supports LangChain
• 🗄️ multiple LLM caching strategies

See Roadmap for upcoming features.

❓ Why?

Many open-source projects for developing and deploying LLM applications have either opinionated designs, particularly regarding deployment, or limitations in terms of scalability. This is where Lanarky comes in. Lanarky is an open-source project that provides Python users with an unopinionated web framework for constructing and deploying LLM applications. By leveraging FastAPI as its foundation, Lanarky ensures that applications built with it are production-ready and can be seamlessly deployed on any cloud provider.

💾 Installation

The library is available on PyPI and can be installed via pip.

pip install lanarky

You can find the full documentation at https://lanarky.readthedocs.io/en/latest/.

🔥 Build your first Langchain app

from dotenv import load_dotenv
from fastapi import FastAPI
from langchain import ConversationChain
from langchain.chat_models import ChatOpenAI

from lanarky import LangchainRouter

load_dotenv()
app = FastAPI()

langchain_router = LangchainRouter(
    langchain_url="/chat",
    langchain_object=ConversationChain(
        llm=ChatOpenAI(temperature=0), verbose=True
    ),
    streaming_mode=0
  )
app.include_router(langchain_router)

See examples/ for list of available demo examples.

Create a .env file using .env.sample and add your OpenAI API key to it before running the examples.

📍 Roadmap

• Add support for LangChain
• Add Gradio UI for fast prototyping
• Add support for in-memory, Redis and GPTCache LLM caching
• Add support for LlamaIndex
• Add support for Guidance
• Add SQL database integration
• Add support for Rebuff
