I'm not sure how accurate this is. I work at a university supporting researchers doing all the typical "AI" research. LLMs, CV, etc. All NVIDIA discounts is the A5000 card for EDU. Maybe one other card they aren't interested in (L40?). Most are buying A6000 and up at consumer prices from companies like Exxact and Supermicro.
I don't think I've seen a single researcher get a free GPU since the V100 era. (DGX-1) system.
