Knowledge Distillation: Teaching Small Models to Think Big

Subscribe to The AI Brief:    / @theaibriefhq   The biggest AI models live in data centers — but your phone runs AI too. How? Knowledge distillation: train a giant teacher model, then train a tiny student to mimic the teacher's soft probability outputs, absorbing the "dark knowledge" of which mistakes are reasonable. We cover the teacher-student setup, why soft targets beat hard labels, temperature scaling, real results (DistilBERT kept 97% performance at 60% size), the hard limits (students can't exceed teachers, biases transfer), and why distillation is moving AI from the cloud to your pocket.
