This paper studies how large reasoning models (LRMs) can continue to improve as human supervision is gradually removed from the learning loop. It examines two key dimensions: the reward axis, which progresses from per-instance human judgments to reusable verifiers and fully autonomous rewards, and the experience axis, which moves from human-curated tasks to self-generated curricula and autonomous co-evolution. A five-level ladder (L0 to L4) maps how much of the learning process remains under human control.

The analysis highlights risks introduced by increasing autonomy, including , feedback drift, curriculum collapse, and environment errors. It also proposes evaluation around three complementary objects: policy capability, feedback fidelity, and experience quality. The paper provides a structured account of current approaches and open problems for scaling LRMs toward superintelligence, and maintains a GitHub repository tracking latest advances.
