Andrej Karpathy's Daily Routine
For builders who could keep going all night. Andrej Karpathy works from about 9:00 AM, Monday to Friday, and keeps weekends off.

Overview
Andrej Karpathy was a founding member of OpenAI in 2015, led AI at Tesla from 2017 to 2022 and in 2025 coined the term "vibe coding". His daily schedule is plain by comparison. About 9:00 AM to 7:00 PM, Monday to Friday, and nothing on weekends.
He aims for 7.5 hours of sleep and describes the week on Threads in 2024. What makes it interesting is the contrast. On X in 2025 he laid out a far more chaotic week from a stretch when he wasn't employed, and his PhD years ran later still, with bed in the early morning and waking at noon.
It suits anyone whose work has no natural edges: researchers, freelancers, builders who could keep going all night and sometimes do. It's also for anyone who has tried the all-hours version and wants a steadier one.
You get a week with a start, a finish and a weekend that's genuinely off. Pick your own hours, then tell the people you work with. The bedtime and the meals are our estimates.
