🎯Core Definition
DeepSeek-R1 Pure RL Reasoning & Self-Correction Emergence establishes the paradigm breakthrough showing that complex long-chain reasoning and self-reflection can spontaneously emerge from zero SFT cold-start data via pure rule-based reinforcement learning (GRPO); the core architecture encompasses: 1) DeepSeek-R1-Zero: bypassing human-annotated CoT cold-starts entirely, applying large-scale RL directly onto base checkpoints (DeepSeek-V3-Base) guided strictly by rule-based deterministic verifiers (exact math matching, unit test compilation, XML formatting tags); 2) Emergence of Dynamic Self-Correction ('Aha Moment'): during RL exploration, models spontaneously discover cognitive backtracking patterns (e.g. 'Wait, let me re-evaluate step 2...') allocating test-time thinking compute autonomously; 3) Multi-Stage Distillation: distilling synthesized reasoning traces into compact dense student models (1.5B, 7B, 14B, 32B).
