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)! ## 🧑‍💻 Installation ### Install from PyPI 📗 **This installs the latest stable version of L♾️pGPT. This is recommended for most users:** ```bash pip install loopgpt ``` 📕 The below two methods install the latest development version of L♾️pGPT. Note that this version maybe unstable: ### Install from source ```bash pip install git+https://www.github.com/farizrahman4u/loopgpt.git@main ``` ### Install from source (dev) ```bash git clone https://www.github.com/farizrahman4u/loopgpt.git@main cd loopgpt pip install -e . ``` ## 🏎️ 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. ## ⚒️ 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 override 3 methods to get your tool up and running! - `args`: A dictionary describing the tool's arguments and their descriptions. - `resp`: A dictionary describing the tool's response and their descriptions. - `run`: The tool's main logic. It takes the tool's arguments as input and returns the tool's response. ```python from loopgpt.tools import BaseTool class GetWeather(BaseTool): @property def args(self): return {"city": "name of the city"} @property def resp(self): return {"report": "The weather report for the city"} def run(self, city): ... ``` L♾️pGPT gives a default ID and description to your tool but you can override them if you'd like: ```python class GetWeather(BaseTool): ... @property def id(self): return "get_weather_command" @property def desc(self): """A description is recommended so that the agent knows more about what the tool does""" return "Quickly get the weather for a given city" ``` Now let's define what our tool will do in its `run` method: ```python import requests # Define your custom tool class GetWeather(BaseTool): ... 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 = {"report": dict(zip(keys, data))} return data except Exception as e: return {"report": 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 import loopgpt # Create Agent agent = loopgpt.Agent() 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'" ] # 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) # Register Tool weather_tool = GetWeather() agent.tools[weather_tool.id] = weather_tool # 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/). ## 💌 Contribute We need A LOT of Help!
