Astra Runtime - Build AI agents, teams, and RAG pipelines in Python with embedded runtime and FastAPI server

Astra Runtime

🚀 Build AI agents, teams, and RAG pipelines in pure Python.

Astra Runtime provides everything you need to build intelligent AI applications:

• Embedded Mode: Use agents directly in your Python code
• Server Mode: Deploy as REST APIs with FastAPI

Installation

pip install astra-runtime

Optional Dependencies

# With MongoDB support
pip install astra-runtime[mongodb]

# With AWS Bedrock support
pip install astra-runtime[aws]

# Everything
pip install astra-runtime[all]

Quick Start

Embedded Mode

import asyncio
from astra import Agent, Gemini

agent = Agent(
    model=Gemini(model="gemini-2.0-flash"),
    instructions="You are a helpful assistant"
)

async def main():
    response = await agent.invoke("Hello!")
    print(response.content)

asyncio.run(main())

Server Mode

from astra import Agent, Gemini
from astra.server import create_app

agent = Agent(
    name="assistant",
    model=Gemini(model="gemini-2.0-flash"),
    instructions="You are a helpful assistant"
)

app = create_app(agents={"assistant": agent})

# Run with: uvicorn main:app --reload

With Tools

from astra import Agent, Tool, tool, Gemini

@tool
def get_weather(city: str) -> str:
    """Get the current weather for a city."""
    return f"The weather in {city} is sunny, 72°F"

agent = Agent(
    model=Gemini(model="gemini-2.0-flash"),
    instructions="You are a weather assistant",
    tools=[get_weather]
)

RAG (Retrieval-Augmented Generation)

from astra import Agent, Rag, LanceDB, HuggingFaceEmbedder, Gemini

# Create RAG pipeline
rag = Rag(
    vector_db=LanceDB(path="./my_db"),
    embedder=HuggingFaceEmbedder()
)

# Ingest documents
await rag.ingest("path/to/documents/")

# Create agent with RAG
agent = Agent(
    model=Gemini(model="gemini-2.0-flash"),
    instructions="Answer questions using the provided context",
    rag=rag
)
