Here's my MIT Mystery Hunt post for the year www.alexirpan.com/2026/01/29/m...

I didn't know where this post was going when I started and I'm not sure where it went now that it ended, but that felt correct in some way. www.alexirpan.com/2025/11/16/a...

First paper since switching into AI safety team🎉 We look at problems that could be solved if the model behaved consistently over a set of prompts, and tried training that in output space and internal activations. Both were effective. See thread or paper for details.

For the past month I have been working on a blog post about niche MLP fandom drama. Well here it is. www.alexirpan.com/2025/07/21/b...

"I don't play gacha games because they're a scam" vs "Let me do one more hyperparam sweep before giving up. One more prompt tuning run. I swear we'll beat baseline. I know it's gonna beat the baseline this time. It's gonna win. This time for sure."

I am now back from #MITMysteryHunt with no memory of anything besides Hunt from MLK weekend. Really this is probably for the best.

It is time for more posts about Neopets www.alexirpan.com/2025/01/09/d...

The ship has sailed, but I wish the ML reporting default was % incorrect rather than % correct. It better matches loss curves and magnifies the capture of edge cases. 95% accuracy -> 97.5% accuracy = meh 5% error -> 2.5% error = omg we've halved the error rate

I wrote some stuff on OpenAI o1 www.alexirpan.com/2024/12/04/l...
