  L♾️pGPT






    A Modular Auto-GPT Framework






    

        

    




L♾️pGPT is a re-implementation of the popular [Auto-GPT](https://github.com/Significant-Gravitas/Auto-GPT) project as a proper python package, written with modularity and extensibility in mind.



## 🚀 Features 🚀



*  **"Plug N Play" API** - Extensible and modular "Pythonic" framework, not just a command line tool. Easy to add new features, integrations and custom agent capabilities, all from python code, no nasty config files!

*  **GPT 3.5 friendly** - Better results than Auto-GPT for those who don't have GPT-4 access yet!

*  **Minimal prompt overhead** - Every token counts. We are continuously working on getting the best results with the least possible number of tokens.

*  **Human in the Loop** - Ability to "course correct" agents who go astray via human feedback.

*  **Full state serialization** - Pick up where you left off; L♾️pGPT can save the complete state of an agent, including memory and the states of its tools to a file or python object. No external databases or vector stores required (but they are still supported)!

## 🏎️ Getting Started



### Setup your OpenAI API Key 🔑



#### Option 1️⃣: Via a `.env` file



Create a `.env` file in your current working directory (wherever you are going to run L♾️pGPT from) and add the following line to it:



```bash

OPENAI_API_KEY=""

```



🛑 **IMPORTANT** 🛑



Windows users, please make sure "show file extensions" is enabled in your file explorer. Otherwise, your file will be named `.env.txt` instead of `.env`.



#### Option 2️⃣: Via environment variables



Set an environment variable called `OPENAI_API_KEY` to your OpenAI API Key.



How to set environment variables:

- [Windows](https://www.architectryan.com/2018/08/31/how-to-change-environment-variables-on-windows-10/)

- [Linux](https://www.freecodecamp.org/news/how-to-set-an-environment-variable-in-linux/)

- [Mac](https://phoenixnap.com/kb/set-environment-variable-mac)



### Create a new L♾️pGPT Agent🕵️:



Let's create an agent in a new [Python](https://python.org) script.



```python

from loopgpt.agent import Agent



agent = Agent()

```



L♾️pGPT uses `gpt-3.5-turbo` by default and all outputs shown here are made using it. GPT-4 users can set `model="gpt-4"` instead:



```python

agent = Agent(model="gpt-4")

```



### Setup the Agent🕵️'s attributes:



```python

agent.name = "ResearchGPT"

agent.description = "an AI assistant that researches and finds the best tech products"

agent.goals = [

    "Search for the best headphones on Google",

    "Analyze specs, prices and reviews to find the top 5 best headphones",

    "Write the list of the top 5 best headphones and their prices to a file",

    "Summarize the pros and cons of each headphone and write it to a different file called 'summary.txt'",

]

```



And we're off! Let's run the Agent🕵️'s CLI:



```python

agent.cli()

```



Save your Python file as `research_gpt.py` and run it:



```bash

python research_gpt.py

```






You can exit the CLI by typing "exit".



### 🔁 Continuous Mode 🔁



If `continuous` is set to `True`, the agent will not ask for the user's permission to execute commands. It may go into infinite loops, so use it at your own risk!



```python

agent.cli(continuous=True)

```



### 💻 Command Line Only Mode



You can run L♾️pGPT directly from the command line without having to write any python code as well:



```bash

loopgpt run

```



Run `loopgpt --help` to see all the available options.



### 🐋 Docker Mode



You can run L♾️pGPT in the previously mentioned modes, using Docker:



```bash

# CLI mode

docker run -i --rm loopgpt:local-dev loopgpt run



# Script mode example

docker run -i --rm -v "$(pwd)/scripts:/scripts" loopgpt:local-dev python /scripts/myscript.py



```



## ⚒️ Adding custom tools ⚒️



L♾️pGPT agents come with a set of builtin tools which allows them to perform various basic tasks such as searching the web, filesystem operations, etc. You can view these tools with `print(agent.tools)`.



In addition to these builtin tools, you can also add your own tools to the agent's toolbox.



### Example: WeatherGPT 🌦️



Let's create WeatherGPT, an AI assistant for all things weather.



A tool inherits from `BaseTool` and you only need to write a docstring to get your tool up and running!



```python

from loopgpt.tools import BaseTool



class GetWeather(BaseTool):

    """Quickly get the weather for a given city



    Args:

        city (str): name of the city

    

    Returns:

        dict: The weather report for the city

    """

    

    def run(self, city):

        ...

```



L♾️pGPT gives a default ID to your tool but you can override them if you'd like:



```python

class GetWeather(BaseTool):

    """Quickly get the weather for a given city



    Args:

        city (str): name of the city

    

    Returns:

        dict: The weather report for the city

    """



    @property

    def id(self):

        return "get_weather_command"

```



Now let's define what our tool will do in its `run` method:



```python

import requests



# Define your custom tool

class GetWeather(BaseTool):

    """Quickly get the weather for a given city



    Args:

        city (str): name of the city

    

    Returns:

        dict: The weather report for the city

    """

    

    def run(self, city):

        try:

            url = "https://wttr.in/{}?format=%l+%C+%h+%t+%w+%p+%P".format(city)

            data = requests.get(url).text.split(" ")

            keys = ("location", "condition", "humidity", "temperature", "wind", "precipitation", "pressure")

            data = dict(zip(keys, data))

            return data

        except Exception as e:

            return f"An error occurred while getting the weather: {e}."

```



That's it! You've built your first custom tool. Let's register it with a new agent and run it:



```python

from loopgpt.tools import WriteToFile

import loopgpt



# Register custom tool type

# This is actually not required here, but is required when you load a saved agent with custom tools.

loopgpt.tools.register_tool_type(GetWeather)



# Create Agent

agent = loopgpt.Agent(tools=[GetWeather, WriteToFile])

agent.name = "WeatherGPT"

agent.description = "an AI assistant that tells you the weather"

agent.goals = [

    "Get the weather for NewYork and Beijing",

    "Give the user tips on how to dress for the weather in NewYork and Beijing",

    "Write the tips to a file called 'dressing_tips.txt'"

]



# Run the agent's CLI

agent.cli()

```



Let's take a look at the `dressing_tips.txt` file that WeatherGPT wrote for us:



dressing_tips.txt

```

- It's Clear outside with a temperature of +10°C in Beijing. Wearing a light jacket and pants is recommended.

- It's Overcast outside with a temperature of +11°C in New York. Wearing a light jacket, pants, and an umbrella is recommended.

```



## 🚢 Course Correction



Unlike Auto-GPT, the agent does not terminate when the user denies the execution of a command. Instead it asks the user for feedback to correct its course.



To correct the agent's course, just deny execution and provide feedback:






The agent has updated its course of action:






## 💾 Saving and Loading Agent State 💾



You can save an agent's state to a json file with:



```python

agent.save("ResearchGPT.json")

```



This saves the agent's configuration (model, name, description etc) as well as its internal state (conversation state, memory, tool states etc).

You can also save just the confifguration by passing `include_state=False` to `agent.save()`:



```python

agent.save("ResearchGPT.json", include_state=False)

```



Then pick up where you left off with:



```python

import loopgpt

agent = loopgpt.Agent.load("ResearchGPT.json")

agent.cli()

```



or by running the saved agent from the command line:



```bash

loopgpt run ResearchGPT.json

```



You can convert the agent state to a json compatible python dictionary instead of writing to a file:



```python

agent_config = agent.config()

```



To get just the configuration without the internal state:



```python

agent_config = agent.config(include_state=False)

```



To reload the agent from the config, use:



```python

import loopgpt



agent = loopgpt.Agent.from_config(agent_config)

```



## 📋 Requirements



- Python 3.8+

- [An OpenAI API Key](https://platform.openai.com/account/api-keys)

- Google Chrome



### Optional Requirements



For official google search support you will need to setup two environment variable keys `GOOGLE_API_KEY` and `CUSTOM_SEARCH_ENGINE_ID`, here is how to get them:



1. Create an application on the [Google Developers Console][google-console].

2. Create your custom search engine using [Google Custom Search][google-custom-search].

3. Once your custom search engine is created, select it and get into the details page of the search engine.

    - On the "Basic" section, you will find the "Search engine ID" field, that value is what you will use for the `CUSTOM_SEARCH_ENGINE_ID` environment variable.

    - Now go to the "Programmatic Access" section at the bottom of the page.

        - Create a "Custom Search JSON API"

        - Follow the dialog by selecting the application you created on step #1 and when you get your API key use it to populate the `GOOGLE_API_KEY` environment variable.



ℹ️ In case these are absent, L♾️pGPT will fall back to using [DuckDuckGo Search](https://pypi.org/project/duckduckgo-search/).
