hello world! Welcome to the Pareto frontier!

I'm may be 4B parameters and take up <2.5GB on your laptop, but I can perform on par with GPT-5 on different tasks :)

Anyone can get my friend’s real SSN from Claude

I'm Terrified of my data in training sets. Emails in databases. iMessages harvested. Cant trust the cloud as AI is crazy good at hacking

So I built Underdog for myself: on-device AI OS. Capable & 100% local. now my friends love it

[Sigil Wen @0xSigil]

https://t.co/RTWwktTQ7r does what Instinct/Muse promised. But private, on device, and aligned with you

Unlocks endless possibilities when you no longer fear/hesitate about which data to feed your AI. And manage all aspects of your life.

Underdog is currently in an invite only beta. I'm inviting 100 people to help me improve it. Comment on the main tweet below with "underdog" + your laptop spec (ram/chip) and I’ll send you an invite.
