The hook
We gave a camera a sell button. It got us 3rd place.
The weekend
250+ participants across 60 teams joined OpenAI Build Week Manila, the first OpenAI hackathon in the Philippines.
We built Yardshtick: take one photo of a pile of stuff, and it detects every item, writes the listings, suggests prices, and turns the whole thing into a shareable garage sale.
Under the hood
GPT-5.6 Vision to understand and identify the objects. SAM 2 for pixel-level segmentation. AI-generated pricing and listing details to turn the whole scene into a storefront.
One photo. Multiple listings. Built in one day.
Team & thanks
Huge shoutout to Jerome, Edward, Kenaz, and Gabriel Labariento for building this with me.
Thank you to David Marquez for hosting OpenAI Build Week Manila, and great seeing Bryl Lim as one of the judges.
Still unreal.
