Idea
Model enhancing recommendation reasoning by integrating perception and cognition for improved user interest understanding and prediction.
Research Paper
Core Innovation
This paper introduces OneReason, which enhances generative recommendation models by combining strong item token perception during pre-training with a three-level cognition-enhanced Chain-of-Thought format in supervised fine-tuning. It also proposes a specialize-then-unify reinforcement learning training recipe to activate reasoning ability, addressing limitations of prior generative models that lacked effective reasoning.
Why It Matters
Recommendation systems often rely on scale but lack reasoning ability, limiting personalized and context-aware suggestions. OneReason addresses this by combining perception of item semantics with cognitive reorganization of user behavior, improving recommendation relevance and user engagement. This approach can scale across multiple domains like e-commerce and advertising, transforming how recommendations adapt to user intent.
Market Size (TAM)
$20–50B TAM for AI-driven recommendation systems; $5–10B SAM from e-commerce, advertising, and streaming platforms. Driven by demand for personalized user experiences and improved engagement.

Research Paper Overview
OneReason Technical Report
Summary
Generative recommendation models in the OneRec family are widely used in services like short-video, live-streaming, advertising, and e-commerce but struggle to activate reasoning ability. OneReason improves reasoning by enhancing item token perception, introducing a three-level cognition-enhanced Chain-of-Thought format, and applying a specialize-then-unify training recipe to boost thinking ability in recommendations.
