Making Expert Reasoning Learnable with Self-Distillation

arXiv:2602.02405v2 Announce Type: replace Abstract: Improving the reasoning capabilities of large language models (LLMs) typically relies either on the model's ability to sample a correct solution to be reinforced or the existence of a stronger model able to solve the problem. However, many difficult problems remain intractable for even current frontier models, preventing the extraction of valid training signals. A promising alternative is to leverage high-quality expert human solutions, yet naive imitation of this data fails because it is fundamentally out-of-distribution: expert solutions ar

Why this matters
Why now

The increasing scale and complexity of LLMs have highlighted limitations in their reasoning capabilities, prompting research into more effective training methods beyond simple reinforcement or stronger models.

Why it’s important

This research provides a potential breakthrough for improving the reasoning capabilities of LLMs in areas where current frontier models struggle, by leveraging expert human solutions more effectively.

What changes

The ability to integrate human expert reasoning into LLMs through self-distillation could lead to more robust and less brittle AI systems, potentially expanding their applicability to complex problem-solving.
