Qwen3.8-27B Reasoning Style Appears Partially Optimized

BitterProfessional7p · reddit · 2026-08-25

User observes that Qwen3.8-27B's thinking process sometimes exhibits 'caveman speech' (no verb conjugation, no articles, short phrases), while other times it is normal. This is speculated to be due to incomplete fine-tuning or RLHF, or a deliberate choice similar to leaked GPT-5.5/5.6 models to improve token efficiency by simplifying reasoning language. The model may have room for improvement in this dimension.
