Production Ready

Auto-scaling, state persistence, and load balancing built-in.

Fully Open Source

Inspect code, extend tools, and deploy on your own infrastructure.

Developer First

This is Simple. Really.

No dense documentation. No proprietary languages. Just Python.

from siphon.agent import Agent
from siphon.plugins import openai, cartesia, deepgram

# Initialize your AI stack
llm = openai.LLM()
tts = cartesia.TTS()
stt = deepgram.STT()

# Define the worker
agent = Agent(
agent_name="sales-rep",
llm=llm, tts=tts, stt=stt,
system_instructions="You are a helpful sales representative..."
)

if __name__ == "__main__":
agent.start()

Stop Renting. Start Owning.

Managed platforms are great for prototypes. SIPHON is built for production at scale.
