Introduction

AgentLego is an open-source library of versatile tool APIs to extend and enhance large language model (LLM) based agents, with the following highlight features:

• Rich set of tools for multimodal extensions of LLM agents including visual perception, image generation and editing, speech processing and visual-language reasoning, etc.
• Flexible tool interface that allows users to easily extend custom tools with arbitrary types of arguments and outputs.
• Easy integration with LLM-based agent frameworks like LangChain, Transformers Agents, Lagent.
• Support tool serving and remote accessing, which is especially useful for tools with heavy ML models (e.g. ViT) or special environment requirements (e.g. GPU and CUDA).

Quick Starts

Installation

Install the AgentLego package

pip install agentlego

Install tool-specific dependencies

Some tools requires extra packages, please check the readme file of the tool, and confirm all requirements are satisfied.

For example, if we want to use the ImageCaption tool. We need to check the Set up section of readme and install the requirements.

pip install -U openmim
mim install -U mmpretrain

Use tools directly

from agentlego import list_tools, load_tool

print(list_tools())  # list tools in AgentLego

image_caption_tool = load_tool('ImageCaption', device='cuda')
print(image_caption_tool.description)
image = './examples/demo.png'
caption = image_caption_tool(image)
