Reasoning Model
A specialized language model designed and trained to prioritize deep, multi-step logical deduction and planning over immediate, reactive text generation.
Think of It Like This
Like consulting a master chess player who sits quietly to calculate ten moves ahead, rather than a commentator who just quickly reacts to the board.
Reasoning models (like OpenAI's o1) are explicitly trained using massive amounts of reinforcement learning to generate long, hidden chains of thought before outputting a final answer. They trade high latency and compute cost for radically improved performance on complex mathematics, coding, and logical puzzles compared to standard conversational models.
