When picking among the 9 AI models from OpenAI the rules are easy:
1) The model with the biggest number is mostly not the best
2) Mini means worse, except for the mini that is the second best
3) o1 pro beats o3-mini-high beats o1 beats o3-mini, naturally, except for creative work which is 4.5 or 4o

Not one VC would ever fund a startup to do the kind of hardcore optimization work that DeepSeek did.
Every VC firm should be asking themselves why.

People are suddenly talking about Apple Intelligence again… 🤔
Almost as if iOS 18.2 just dropped.
This place is slowly getting to the critical mass of breaking news buzz it was made for! #🦋

Has anyone actually met their cofounder on YC Cofounder Matching?
I keep getting notifications about people from my school who just joined and I’m wondering how does it have anything to do with fit.

Am I the only one who remaps Caps Lock to `~ on all my keyboards?
I wish I could hardware-mod every single one rather than having to use Karabiner Elements on some.
This is NuPhy Air75 v2 btw - my all time favorite, hardware remapped.

For the largest health insurer in the US, AI’s error rate is like a feature, not a bug.

It's true, if you completely "deactivate" your Twitter account for more than 30 days your old username becomes available for others to use (and misuse). We should delete the app instead of the account

For the first time since the election, I started my morning listening to the news. Now I can't stop thinking about how much happier my mornings are without the news and how much more clear my mind is when I start my day with music or silence.
