Making a LLM Prediction Game with Node.js and Express

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).

I love that it's personalized. When I'm stuck, I don't have to hope my Google searches come out successful. The AI mentor Cosmo knows exactly what I need.

It's an amazing product and exceeded my expectations, helping me prepare for my job interviews. Hands-on learning requires you to actually know what you are doing.

Alex Bush

I'm really impressed by the AI tutor Cosmo's feedback about my code. It's honestly kind of insane to me that it's so targeted and specific.

I tried Leetcode but it was too disorganized. CodeSignal covers all the topics I'm interested in and is way more structured.
