"Starting today, free plan users can also try OpenAI o3-mini by selecting ‘Reason’ in the message composer or by regenerating a response. This marks the first time a reasoning model has been made available to free users in ChatGPT." Competition is good. #deepseek #openai

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.

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.

“Even for the patients who appeal their AI-backed denials and succeed at getting them overturned, the win is short-lived—UnitedHealth will send new denials soon after, sometimes within days.” Damn, this is messed up. #aisky #healthcare #healthtech

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.
