Andrej Karpathy - @karpathy
Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

(vs an HN blog author),
networks are communication and dissemination tools,
not principled stances.
Super offending to my sensibilities seeing the extent of slop in replies, and this is months and months ago now. Unbridled poorly prompted GPT-4o replies.
The main posts from smart/funny people are just as good as they would be written elsewhere, yes, but like at a restaurant, atmosphere’s pretty important too… don’t want to eat a tomahawk steak on an airport runway (whether or not the airport’s associated with My Heart Goes Out To You non-Roman non-salutes)
If you can screenshot all the good stuff and put it on Mastodon, thank you! ;) (hehe no perfect solutions to this thang)
[1] omg someone prompted GPT to use uncommon words and lowercase letters, and they posted the stupidest model output I’ve ever seen as “their” reaction… it was super disrespectful to make humans read even those few contrived sentences
Karpathy’s so smart and he has to deal with the reply quality we see on XCancel there… one click away from Hacker News and suddenly every reaction is trash instead of insight and deep insight we see here
(Plus the trash I post, but we’ve got some range, not monotonous spam & model output)
… Memphis/Southaven residents will get more air pollution.
Nobody who isn't fully on board with white supremacy (et tu, Andrej?) should be using Twitter at this point.
