Making a LLM Prediction Game with Node.js and Express

Overview

Build a JavaScript-based LLM game with Node.js + Express, where players guess the model’s next word. Across three courses, you’ll create a daily-refreshed, Wordle-style game with a web frontend. Players earn points by predicting the LLM’s next word based on semantic similarity (OpenAI embeddings).
