LangChain

Synapse LLM adapter for LangChain that exposes the full Synapse model router, including fallback chains and structured outputs, as a drop-in ChatModel class.

Overview

Use Synapse OS as a drop-in LLM replacement within your existing LangChain agentic workflows. Synapse acts as a single `ChatModel` that handles fallback routing invisibly behind the scenes.

Quickstart

Import the Synapse integration from the LangChain community package.

python
1
from langchain_community.chat_models import ChatSynapse
2
from langchain_core.messages import HumanMessage
3
chat = ChatSynapse(api_key="sk_live_...",routing_strategy="latency_optimized")chat.invoke([HumanMessage(content="Initialize sequence.")])
