Cradle: Empowering Foundation Agents Towards General Computer Control

[Website] [arXiv] [PDF]

The Cradle framework empowers nascent foundation models to perform complex computer tasks via the same unified interface humans use, i.e., screenshots as input and keyboard & mouse operations as output.

📢 Updates

• 2024-06-27: A major update! Cradle is extened to four games: RDR2, Stardew Valley, Cities: Skylines, and Dealer's Life 2 and various software, including but not limited to Chrome, Outlook, Capcut, Meitu and Feishu. We also release our latest paper. Check it out!

💾 Installation

Prepare the Environment File

We currently provide access to OpenAI's and Claude's API. Please create a .env file in the root of the repository to store the keys (one of them is enough).

Sample .env file containing private information:

OA_OPENAI_KEY = "abc123abc123abc123abc123abc123ab"
RF_CLAUDE_AK = "abc123abc123abc123abc123abc123ab" # Access Key for Claude
RF_CLAUDE_SK = "123abc123abc123abc123abc123abc12" # Secret Access Key for Claude
AZ_OPENAI_KEY = "123abc123abc123abc123abc123abc12"
AZ_BASE_URL = "https://abc123.openai.azure.com/"
RF_CLAUDE_AK = "abc123abc123abc123abc123abc123ab"
RF_CLAUDE_SK = "123abc123abc123abc123abc123abc12"
IDE_NAME = "Code"

OA_OPENAI_KEY is the OpenAI API key. You can get it from the OpenAI.

AZ_OPENAI_KEY is the Azure OpenAI API key. You can get it from the Azure Portal.

OA_CLAUDE_KEY is the Anthropic Claude API key. You can get it from the Anthropic.

RF_CLAUDE_AK and RF_CLAUDE_SK are AWS Restful API key and secret key for Claude API.

IDE_NAME refers to the IDE environment in which the repository's code runs, such as PyCharm or Code (VSCode). It is primarily used to enable automatic switching between the IDE and the target environment.

Setup

Python Environment

Please setup your python environment and install the required dependencies as:

# Clone the repository
git clone https://github.com/BAAI-Agents/Cradle.git
cd Cradle

# Create a new conda environment
conda create --name cradle-dev python=3.10
conda activate cradle-dev
pip install -r requirements.txt

Install the OCR Tools

1. Option 1
# Download best-matching version of specific model for your spaCy installation
python -m spacy download en_core_web_lg

or

# pip install .tar.gz archive or .whl from path or URL
pip install https://github.com/explosion/spacy-models/releases/download/en_core_web_lg-3.7.1/en_core_web_lg-3.7.1.tar.gz

2. Option 2
# Copy this url https://github.com/explosion/spacy-models/releases/download/en_core_web_lg-3.7.1/en_core_web_lg-3.7.1.tar.gz
# Paste it in the browser and download the file to res/spacy/data
cd res/spacy/data
pip install en_core_web_lg-3.7.1.tar.gz

🚀 Get Started

Due to the vast differences between each game and software, we have provided the specific settings for each of them below.

1. Red Dead Redemption 2
2. Stardew Valley
3. Cities: Skylines
4. Dealer's Life 2
5. Software

🌲 File Structure

Since some users may want to apply our framework to new games, this section primarily showcases the core directories and organizational structure of Cradle. We will highlight in "⭐⭐⭐" the modules related to migrating to new games, and provide detailed explanations later.

📚 Migrate to New Game

Since each game's settings and the operating systems they are compatible with are different, Cradle cannot simply replace one game name to migrate to a new game. We suggest considering each game specifically. For example, RDR2, an independent AAA game, requires real-time combat, so we need to pause the game to wait for GPT-4o's response and then unpause the game to execute the actions. Stardew has the same issue. Other games like Dealer's Life 2 and Cities: Skylines do not have real-time requirements, so they do not need to pause. If the new game is similar to the latter, we recommend copying Cities: Skylines' implementation and following its implementation path to create the corresponding modules. Although each game may differ significantly, our Cradle framework can still achieve a unified adaptation for a game. Assuming the new game's name is newgame, the specific migration pipeline can be found Migrate to New Game Guide.
