Teacher-Free Self-Training Amplifies but Does Not Compound: A Pass@$K$ Crossover on a Free-Verifier Domain
arXiv:2606.07856v1 Announce Type: new Abstract: When a language model trains on its own verified outputs, does it acquire capability beyond its base, or merely get better at expressing capability the base already had? We make the question decidable with a teacher-free "constellation" -- a generator, a learned critic, and a free exact verifier -- on a FlashFill-style "trapdoor" DSL, where verified (problem, solution) pairs are cheap to synthesize, hard to invert, and free to check exactly. Everything runs on one 4-bit Qwen3-4B on a single 24 GB GPU, with no model in the loop larger than the bas
The proliferation of language models and increasing compute availability make self-training a critical research area for autonomous AI development.
This research suggests a pathway for language models to improve capability without requiring continuous human labeling or external teacher models, potentially accelerating AI development at lower cost.
The understanding of how self-training impacts AI capability, specifically that it can amplify existing capabilities rather than creating new ones from scratch.
