Researchers have introduced TREK (Teacher-Routed Exploration via Forward KL), a novel staged procedure designed to enhance the reasoning capabilities of AI models, particularly on challenging prompts. TREK utilizes distillation not for direct imitation but to expand the model's exploration support. This method can leverage external or internal teachers and efficiently identifies valuable hard-prompt samples for consolidation. When applied to mathematical reasoning tasks, TREK improved Qwen3 models on AIME 2024 and AIME 2025 benchmarks, and on agentic tasks, it significantly raised success rates for ALFWorld and ScienceWorld.
