Transcript

I'm almost six months out from ACL surgery and I want to recover as safely and safely as possible. So I asked Grok 4.5 and Opus 4.8 to build me adaptive training plans. I gave both models the same prompt. Build a web app that generates a training plan based on my Strava data and my surgery details. Lets me log how the workouts feel and adapts the plan based on my feedback. Grok finished in 5 minutes and 14 seconds using 960,000 tokens. Opus took 12 and a half minutes using 2.6 million tokens. Grok ended up being around eight times cheaper than Opus, costing $2.69 while Opus cost $23.40. And here are the finished apps. Functionally they are very similar, doing everything that I specified in the prompt. I logged a workout in both apps and Grok's version actually let me customize the feedback more than Opus's, asking about my knee stability and symmetry. And the more the app knows, the better it will be able to adapt my training plan going forward. Grok 4.5 is actually in a different weight class than Composer 2.5, but unlike Composer, it is built for more than just coding. Comment 'cursor' and I will DM you 50% off your first month plus doubled Grok 4.5 usage for the first week! This video is sponsored by Cursor.
