General Instruction Following And Human Preference Alignment

Alibaba's 32B reasoning model with chain-of-thought.

Unique: Uses a two-stage RL training approach where the second stage applies a general reward model and rule-based verifiers to align with human preferences across diverse tasks, enabling reasoning models to maintain instruction-following capability beyond specialized domains

vs others: Balances strong reasoning capability with general instruction-following through preference-aligned training, enabling use cases that require both transparent reasoning and practical task execution without requiring separate specialized models

Unique: Combines supervised instruction fine-tuning with learned reward models and PPO optimization in a unified pipeline, enabling scalable incorporation of human preferences without requiring human annotation of every model output. The three-stage approach separates preference learning from policy optimization, allowing the reward model to capture nuanced human preferences that can then guide the language model.

vs others: More scalable and controllable than direct human feedback on every output, and more aligned with human preferences than standard supervised fine-tuning on instruction-following examples alone, because it explicitly optimizes for human-preferred behavior through a learned reward signal.
