<i>Building <b>agents</b> that can browse the web by following instructions and talking to you</i>

[!IMPORTANT] We are thrilled to release Llama-3-8B-Web, the most capable agent built with 🦙 Llama 3 and finetuned for web navigation with dialogue. You can download the agent from the 🤗 Hugging Face Model Hub.

WebLlama helps you build powerful agents, powered by Meta Llama 3, for browsing the web on your behalf	Our first model, Llama-3-8B-Web, surpasses GPT-4V (*zero-shot) by 18% on WebLINX

About the project

If you use WebLlama in your research, you can cite the ICML 2024 paper upon which the training and evaluation are originally based on, by adding the following to your bibtex file:

Example usage (in latex):

We use the WebLlama library, which builds on top of WebLINX \citep{lu_2024_weblinx}.

We use Llama-3-8B-Web, a model finetuned on WebLINX demonstrations \citep{lu_2024_weblinx}.

Modeling

[!NOTE] The model is available on the 🤗 Hugging Face Model Hub as McGill-NLP/Llama-3-8B-Web. The training and evaluation data is available on Hugging Face Hub as McGill-NLP/WebLINX.

Our first agent is a finetuned Meta-Llama-3-8B-Instruct model, which was recently released by Meta GenAI team. We have finetuned this model on the WebLINX dataset, which contains over 100K instances of web navigation and dialogue, each collected and verified by expert annotators. We use a 24K curated subset for training the data.

It surpasses GPT-4V (zero-shot *) by over 18% on the WebLINX benchmark, achieving an overall score of 28.8% on the out-of-domain test splits (compared to 10.5% for GPT-4V). It chooses more useful links (34.1% vs 18.9% seg-F1), clicks on more relevant elements (27.1% vs 13.6% IoU) and formulates more aligned responses (37.5% vs 3.1% chr-F1).

It's extremely straightforward to use the model via Hugging Face's transformers, datasets and hub libraries:

from datasets import load_dataset
from huggingface_hub import snapshot_download
from transformers import pipeline

# We use validation data, but you can use your own data here
valid = load_dataset("McGill-NLP/WebLINX", split="validation")
snapshot_download("McGill-NLP/WebLINX", repo_type="dataset", allow_patterns="templates/*")
template = open('templates/llama.txt').read()

# Run the agent on a single state (text representation) and get the action
state = template.format(**valid[0])
agent = pipeline("McGill-NLP/Llama-3-8b-Web")
out = agent(state, return_full_text=False)[0]
print("Action:", out['generated_text'])

# Here, you can use the predictions on platforms like playwright or browsergym
action = process_pred(out['generated_text'])  # implement based on your platform
env.step(action)  # execute the action in your environment

Evaluation

We believe short demo videos showing how well an agent performs is NOT enough to judge an agent. Simply put, we do not know if we have a good agent if we do not have good benchmarks. We need to systematically evaluate agents on wide range of tasks, spanning from simple instruction-following web navigation to complex dialogue-guided browsing.

This is why we chose WebLINX as our first benchmark. In addition to the training split, the benchmark has 4 real-world splits, with the goal of testing multiple dimensions of generalization: new websites, new domains, unseen geographic locations, and scenarios where the user cannot see the screen and relies on dialogue. It also covers 150 websites, including booking, shopping, writing, knowledge lookup, and even complex tasks like manipulating spreadsheets. Evaluating on this benchmark is very straightforward:

cd modeling/

# After installing dependencies, downloading the dataset, and training/evaluating your model, you can evaluate:
python -m weblinx.eval # automatically find all `results.jsonl` and generate an `aggregated_results.json` file

# Visualize your results with our app:
cd ..
streamlit run app/Results.py

👷‍♀️ Next steps
We are planning to evaluate our models on more benchmarks, including Mind2Web, a benchmark for automatic web navigation. We believe that a good agent should be able to navigate the web both through dialogue and autonomously, and potentially attain even broader ranges of capabilities useful for real-world web browsing.

Data

Although the 24K training examples from WebLINX provide a good starting point for training a capable agent, we believe that more data is needed to train agents that can generalize to a wide range of web navigation tasks. Although it has been trained and evaluated on 150 websites, there are millions of websites that has never been seen by the model, with new ones being created every day.

This motivates us to continuously curate, compile and release datasets for training better agents. As an immediate next step, we will be incorporating Mind2Web's training data into the equation, which also covers over 100 websites.

Deployment

We are working hard to make it easy for you to deploy Llama web agents to the web. We want to integrate WebLlama with existing deployment platforms, including Microsoft's Playwright, ServiceNow Research's BrowserGym, and other partners.

At the moment, we offer the following integrations:

• Browsergym: Please find more information in examples/README.md and docs/README.md.

Code

The code for finetuning the model and evaluating it on the WebLINX benchmark is available now.

• Modeling: You can find the detailed instructions in modeling for training Llama-3-8B-Web on the WebLINX dataset.
• Examples: We provide a few example for using the webllama API and models, including web API, end-to-end, and BrowserGym integration. You can find them in examples.
• App: We provide a simple Streamlit app for visualizing the results of your model on the WebLINX benchmark. You can find the code in app.
• Docs: We provide detailed documentation for the code in docs.
