Welcome!
My name is John Hallman, and this is my blog. I mostly write about AI, technology, and business, though at times I touch on economic and political issues as well.
I currently work on pretraining at OpenAI, though I've done a bunch of other stuff in the past, including but not limited to RL, bio AI, healthcare, optimizers, etc.
I grew up in Sweden to a Swedish father and a Japanese mother, and so any issues or topics touching on race, multiculturalism, and immigration are very dear to me. I also competed internationally in math and figure skating back in my youth, having represented Sweden at the 2012 figure skating youth olympic games, and the 2016 international mathematical olympiad.
If anything I mentioned above speaks to you, don’t hesitate to DM me here on Substack! And, if any of my writing interests you, please do feel free to subscribe!
