TREK Improves GRPO's Exploration Ability
burny_tech · x · 2026-07-10
The post introduces the paper TREK: improving GRPO on hard tasks by addressing exploration. When the student model repeatedly samples wrong paths, a teacher or the same model with extra context is used to find verified correct solutions, then only the paths closest to these correct solutions are taught, improving sampleability and helping GRPO continue optimization.
