DeepSeek R1 (Reasoning)

DeepSeek's reasoning model with chain-of-thought. Slow (76s avg) but deliberate — the reasoning traces show it carefully planning each tool call. Moderate error rate (12.5%) partly from JSON formatting issues. Small sample size but shows promise for complex checkout flows where thinking through validation errors matters.
