Qwen SkillDuet Co-Evolves Models, Skills

SkillDuet’s key idea is treating skills as a living learning substrate rather than static prompt memory.

• –Local skills guide on-policy distillation while the model trains
• –Its Strength score selects skills that most change model responses
• –Global consolidation preserves useful guidance as model behavior evolves
• –Reported gains are promising, but evaluation remains limited to agent benchmarks
• –The main open question is whether retained skills generalize without becoming stale or harmful
