Rapid advances in rival open‑source models this year have increased pressure on
ByteDance. At a recent internal Seed team meeting founder Zhang Yiming urged a
long‑term approach to model development, saying the firm will refuse
distillation—not using others' outputs to chase temporary ranking gains—and
should be willing to sacrifice some short‑term returns for long‑term goals.
ByteDance has banned distillation of open‑source models internally and tightened
controls, including API detection, to enforce the restriction; Zhang said
distillation would interfere with genuine long‑term technical breakthroughs.
