I ask because every serious study on using modern generative AI tools tends to conclude fairly immediate and measurable deleterious effects on cognitive ability.
There are a lot of studies, and I can't say I've read all of them, but the ones I have read, there hasn't been much focus on how the participants used the LLM to learn. My guess is that it has a lot of effect on the end results. Someone just asking for the answer and then thinking "Lets remember this" will have very different results than someone who does the Socratic method of learning together with a LLM, as just one example.
