What is Reasoning Model?
Reasoning Model: Reasoning models (like o3, DeepSeek R1) use chain-of-thought processing internally to solve complex problems.
Reasoning Model Explained
Reasoning models spend extra computation "thinking" before responding. This internal deliberation improves performance on math, coding, and logic tasks. However, reasoning adds to output tokens (you're charged for thinking tokens too). These models excel at complex problems but are overkill for simple tasks. o3 costs $10/$40 per 1M tokens but can solve problems other models can't.
