"High stability, plug-in support, multi-modal - large model native instant messaging robot platform"

Project Highlights

Enterprise-level conversation solution : integrates mainstream big models and supports multi-platform instant messaging
Plug-in extension architecture : 50+ plug-in ecosystems meet various business scenarios
Production-level stability : a complete testing system ensures 7x24 hours of stable operation
Out-of-the-box : Baota/Docker/source code three deployment methods optional

Core Function Panorama

? Plugin ecosystem

Supports event monitoring, Agent, process control and other extension methods, and has implemented:

  • Intelligent work order system
  • Knowledge Base Q&A
  • Multi-turn dialogue management
  • Third-party service connection
# Example: Creating a weather query plugin
from  langbot.plugins  import  BasePlugin

class WeatherPlugin (BasePlugin) : 
    triggers = [ "weather" ]
    
    async def handle_message (self, message) :  
        city ​​= message.content.split()[ -1 ]
        # Call the weather API to get data
        return f" {city} Today is sunny, 25℃~30℃"
