        ## Introduction
        
        Lagent is a lightweight open-source framework that allows users to efficiently build large language model(LLM)-based agents. It also provides some typical tools to augment LLM. The overview of our framework is shown below:

        ### Major Features
        
        - **Support multiple kinds of agents out of box.** Lagent now supports [ReAct](https://arxiv.org/abs/2210.03629), [AutoGPT](https://github.com/Significant-Gravitas/Auto-GPT) and [ReWOO](https://arxiv.org/abs/2305.18323), which can drive the large language models(LLMs) for multiple trials of reasoning and function calling.
        
        - **Extremely simple and easy to extend.** The framework is quite simple with a clear structure. With only 20 lines of code, you are able to construct your own agent. It also supports three typical tools: Python interpreter, API call, and google search.
        
        - **Support various large language models.** We support different LLMs, including API-based (GPT-3.5/4) and open-source (LLaMA 2, InternLM) models.
        
        ## Getting Started
        
        Please see the [overview](docs/en/get_started/overview.md) for the general introduction of Lagent. Meanwhile, we provide extremely simple code for quick start. You may refer to [examples](examples/) for more details.
        
        ### Installation
        
        Install with pip (Recommended).
        
        ```bash
        pip install lagent
        ```
        
        Optionally, you could also build Lagent from source in case you want to modify the code:
        
        ```bash
        git clone https://github.com/InternLM/lagent.git
        cd lagent
        pip install -e .
        ```
        
        ### Run a ReWOO agent with GPT-3.5
        
        Below is an example for running ReWOO with GPT-3.5
        
        ```python
        from lagent.agents import ReWOO
        from lagent.actions import ActionExecutor, GoogleSearch, LLMQA
        from lagent.llms import GPTAPI
        
        llm = GPTAPI(model_type='gpt-3.5-turbo', key=['Your OPENAI_API_KEY'])
        search_tool = GoogleSearch(api_key='Your SERPER_API_KEY')
        llmqa_tool = LLMQA(llm)
        
        chatbot = ReWOO(
            llm=llm,
            action_executor=ActionExecutor(
                actions=[search_tool, llmqa_tool]),
        )
        
        response = chatbot.chat('What profession does Nicholas Ray and Elia Kazan have in common')
        print(response.response)
        >>> Film director.
        ```
        
        ### Run a ReAct agent with InternLM
        
        NOTE: If you want to run a HuggingFace model, please run `pip install -e .[all]` first.
        
        ```python
        from lagent.agents import ReAct
        from lagent.actions import ActionExecutor, GoogleSearch, PythonInterpreter
        from lagent.llms import HFTransformer
        
        llm = HFTransformer('internlm/internlm-7b-chat-v1.1')
        search_tool = GoogleSearch(api_key='Your SERPER_API_KEY')
        python_interpreter = PythonInterpreter()
        
        chatbot = ReAct(
            llm=llm,
            action_executor=ActionExecutor(
                actions=[search_tool, python_interpreter]),
        )
        
        response = chatbot.chat('若$z=-1+\sqrt{3}i$,则$\frac{z}{{z\overline{z}-1}}=\left(\ \ \right)$')
        print(response.response)
        >>> $-\\frac{1}{3}+\\frac{{\\sqrt{3}}}{3}i$
        ```
