ADaPT: Token-Level Decoupling for Efficient Large Reasoning Models

arXiv:2606.19919v1 Announce Type: new Abstract: Large reasoning models rely on long chain-of-thought to achieve strong performance, but applying such reasoning uniformly incurs high computational cost. Existing efficiency-oriented methods attempt to shorten or mix reasoning strategies, yet often degrade reasoning capability. We identify the root cause as sequence-level coupling between efficiency incentives and correctness optimization, which implicitly penalizes long but correct reasoning trajectories. To address this issue, we propose Adaptive Dual-Process Thinking (ADaPT), a token-level dua

Why this matters
Why now

The increasing scale and computational cost of large reasoning models necessitate new efficiency paradigms to sustain progress and broader application.

Why it’s important

Efficient large reasoning models can make advanced AI capabilities more accessible and deployable, reducing the financial and computational barriers to their use and development.

What changes

The proposed ADaPT method fundamentally alters how computational resources are allocated within large reasoning models by decoupling efficiency from correctness at a token level.
