The body of literature on learning theory, and beyond that on specific types of learning and specific mediums such as learning from text is so rich there are way more useful models to draw from. Believe it or not, prellm, researchers in the textual learning field had already demonstrated you can achieve performance equal or better than novice tutors using pretty basic computer aids that follow specific hint/pump interaction structures. Guiding an LLM to use these findings has evidence backing it and is way better than telling it "i guess be like socrates". The problem is, to realize there might be richer more effective and highly researched ways of tackling the problem beyond the first fart of a thought you had one afternoon requires the deep respect for expertise and specialization that precisely basically everyone in the AI space right now fundamentally lacks.
Trying to diagrams/animations didn't yield good results even with frontier models. But pure text, any model does a decent job.
So it may be very slow or become unavailable, back end can't handle that, no caching whatsoever.
