AidGenSE 开发者文档

Introduction

AidGenSE is a generative AI HTTP service based on the AidGen SDK wrapper that adapts to the OpenAI HTTP protocol. Developers can call generative AI through HTTP and quickly integrate it into their applications.

💡Note

All large language models supported by Model Farm achieve inference acceleration on Qualcomm NPUs through AidGen.

Starting the Service

# Start OpenAI API service for the corresponding model
aidllm start api -m <model_name> 

# Check status
aidllm status api

# Stop service               
aidllm stop api

# Restart service
aidllm restart api

💡Note

Default port number is 8888

Chat Testing

Using Web UI for chat testing

# Install UI frontend service
sudo aidllm install ui

# Start UI service
aidllm start ui

# Check UI service status
aidllm status ui

# Stop UI service
aidllm stop ui

💡Note

After the UI service starts, access http://ip:51104
