Tipjai Research

About the lab

Tipjai Research is the research side of Tipjai, the tipping platform for Thai creators. We build the tools creators use, measure how good they are, and publish the results for anyone to check.

How we measure and publish

  • Blind test setsEvery measurement uses a test set written apart and frozen in advance; nothing is tuned after seeing results. Spent sets are released; new ones are kept for the next version.
  • Blind listeningWhoever rates does not know whose voice they hear, and every clip is matched in loudness first.
  • Numbers from filesNumbers on this site are read straight from the measurement output. None is typed by hand.
  • Losses publishedLosses, inconclusive results and problems found later are published just like wins.
  • What we keepHow a model is built: its components, data, sizes and settings. Results and methods are open to checking; the recipe stays in-house.
