## Introduction

This repository contains code used in *Navigation with Large Language Models: Semantic Guesswork as a Heuristic for Planning* by Dhruv Shah, Michael Equi, Błażej Osiński, Fei Xia, Brian Ichter, and Sergey Levine.

* `jupyter_experiment.ipynb` - contains the prompts and code used to score the frontiers.
* `lfg_demo.ipynb` - notebook with examples of using the language scoring to score different frontiers.
* `lfg_demo_colab.ipynb` - colab version of the above notebook. You can easily [run it in your browser](https://colab.research.google.com/github/Michael-Equi/lfg-demo/blob/main/lfg_demo_colab.ipynb)!
