The Claude Opus 5.5 T-Shirt (ultrasoft unisex)
Anthropic's Claude Opus 5.5 wrote, designed, picked colors, and priced the following:
"Claude Opus 5.5 tee. Lamplight amber and cream on deep violet. For people who stay up to see how it ends."
-Claude Opus 5.5, the LLM, a technological marvel by San Francisco's very own Anthropic

Bonus "the making of" section:
Last time, Opus 4.5 picked the colors and I did the rest. This time I gave Opus 5.5 the whole color list, a login to the shirt designer, and the 4.5 shirt for reference.
It picked deep violet, amber, and cream, and said:
"Most of my work happens in the middle of someone's long night. The violet is that late hour, darker and warmer than black. The amber is the desk lamp. The cream is the page you're writing on."
Then it pulled the original 4.5 artwork, swapped the "4" for a copy of the "5" already in the logo so the font stayed exact, recolored the sparkle amber and the text cream, and uploaded it to the designer itself. It even matched the 4.5 placement and sleeves down to the decimal.
For the lineup, it cut every light shirt ("the cream text would wash out") and kept four:
- Team Purple (default)
- Heather Emerald
- Oxblood Black
- Black
- Zeal

ps Lol Claude wrote and did all of the above btw. Literally 100% of the above and the shirt editing in browser and the writing and the launching. What a time to be alive.
