For the ones who let the model think longer.

This minimalist tee features "ultrathink" in clean typography—an Easter egg for developers who know that sometimes the best code comes from giving Claude Code the time and tokens to reason deeply. Wear it to the coffee shop, the office, or your late-night debugging sessions.

Premium cotton blend, preshrunk, with a comfortable fit that doesn't quit before your AI pair programming session does. Because if you're going to optimize for test-time compute in your terminal, you might as well look good doing it.
