RCI Agent for MiniWoB++

Welcome to the codebase for our paper, "Language Models can Solve Computer Tasks". In this codebase, you will find the implementation of our RCI agent, which uses a pre-trained language model to execute computer tasks in MiniWoB++ benchmark guided by natural language. The agent employs a simple RCI prompting scheme that allows it to improve its outputs.

Dependencies

The RCI agent is implemented in Python 3.9 and requires the following dependencies:

• gym
• openai
• selenium
• Pillow
• regex

pip install -r requirements.txt

Note: MiniWoB++ is not officially supported on Windows. Please refer to this issue.

Usage

Setup

To run the code, you must first install MiniWoB++ and configure your OpenAI API key. MiniWoB++ is integrated with the OpenAI Gym environment. Navigate to the computergym directory and execute the following command to install it:

cd computergym
pip install -e .

Once that's done, you need to write your OpenAI API key in the example_config.json file, then rename the file to config.json

Run

To run the code, simply execute the following command:

python main.py --env [TASK NAME] --llm [LLM NAME] --num-episodes [NUM EPISODES] --erci [NUM Explicit RCI] --irci [NUM Implicit RCI] --sgrounding

Here are the arguments you need to specify:

• --env: Name of the MiniWoB++ task you want to run. You can see the list of available tasks in available_tasks.txt
• --llm: Name of the language model you want to use. The model name and corresponding API name are specified below:
  • chatgpt: "gpt-3.5-turbo"
  • davinci: "text-davinci-003"
  • ada: "ada"
  • babbage: "babbage"
  • curie: "curie"
  • davinci1: "davinci"
  • davinci2: "text-davinci-002"
• --num-episodes: Number of episodes to run the task
• --erci: The number of explicit RCI loop for an action plan. -1 will remove the action plan sampling.
• --irci: The number of implicit RCI loop for the agent grounding.
• --sgrounding: If this is True, then the state grounding update is enabled.
• --headless: If this is True, then the MiniWoB++ environment will run in headless mode.

Consider running the following command to verify if everything is functioning correctly:

python main.py --env choose-list --llm chatgpt --num-episodes 1 --irci 1 --sgrounding

Evaluation

Our project's approach has yielded impressive results, with our agent achieving the second-highest score out of all tested models. We have observed that our agent outperforms the baselines, with the exception of CC-Net (SL + RL), which uses dictionary-based typing actions.

What sets our RCI agent apart is that it accomplished this feat using 120 times fewer samples than WebN-T5-3B and 11,000 times fewer samples than CC-Net. Obtaining expert demonstrations and defining reward functions for computer tasks can be a daunting challenge, but our research highlights the potential of using LLMs to overcome these obstacles and achieve success in general computer tasks.
