The AI designed and ran a simulation that corrected the author's own claim

A statistician had argued that class balancing helps mini batch gradient descent. He had the AI Astra design and run a simulation to test the claim, and the results partly corrected him: oversampling sped convergence but hurt probability accuracy, while importance weighted oversampling kept most of the speed and the accuracy. The code was cross checked with AI, and he posted the corrected conclusion as an answer.

The AI recommended plants for his spider enclosures without checking pesticide treatment; about $60 of plants were unusable

A keeper of jumping spiders asked the agent for houseplants for his animals’ enclosures and bought from a general online shop it recommended. The agent never checked whether the seller treats its plants. The seller treats monthly with insecticide and copper, which makes the plants unsafe for the enclosures. About $60 of plants were unusable, and he lost time arranging a refund.

GPT scans his computer for new security flaws and patches it

He gave GPT a security audit skill that checks his machine against newly published vulnerabilities, patches what it can, and warns him about the rest. He runs it whenever new CVEs land, and says the patches need care because a fix can cause as much trouble as the flaw.

Built a dinner outfit from pieces the user photographed and uploaded from

A young man (OUT OF OFFICE, 30K followers) photographed his wardrobe and fed the pieces to the AI before a dinner reservation. Nova chose a black henley and dark wide-leg jeans, cross-checked his calendar and noticed the reservation was outside so it advised layering a long-sleeve, then recommended loafers over sneakers plus a silver watch and bracelet.

HobbiesPartly worked

The AI added only half the dates to my calendar

He asked the AI to add some dates to his Outlook calendar. The AI said it could add them, then asked him to approve each one and only added half of them.

This only partly worked. Worth knowing before you try it.

The AI made my adapter bracket in one shot

He gave the AI a CAD file he could not even open, plus a few measurements he took with digital calipers. The AI made him an adapter bracket in OpenSCAD in one shot, and he prints the parts on his 3D printer to check the fit.

The AI built me a new VPN app for my Chromecast in 20 minutes

His Chromecast would not connect to his home VPN, which uses IKEv2, while he stayed at an Airbnb, and the VPN apps he tried would not work on it. He gave the AI his certificates and the AI wrote a new VPN app for the Chromecast in about 20 minutes. He says it works perfectly.

Mine 10 years of my own notes into a personal idea map

A writer had the AI read more than 1,000 of his Apple Notes from 2016 to today — letters, journals and dream logs — and build a private local site mapping the ideas he keeps returning to. It also produced a model of his writing voice and a query tool to ask new questions at lower token cost.
