The same reasoning effort parameter means reducing thinking on a model that reasons by default, but means starting to think on a model that does not reason by default, the semantics being opposite.

UnverifiedFor a model that does not reason by default, once any reasoning effort field (including low) is explicitly passed in the request, it is equivalent to asking the model to start thinking, which causes a model that should be fast to become slow or even return an empty string.79% similarUnverifiedAligned models tend to proactively introduce disclaimers or interrupt conversation flow when handling hypothetical reasoning and role-playing tasks, behaviors that are almost nonexistent in base models.76% similarVerifiedReasoning Effort is essentially a parameter that controls the depth of the model's chain of thought; the higher the level, the more internal reasoning steps the model is allowed, and latency and cost rise proportionally.76% similarUnverifiedReasoning models typically return a separate reasoning or thinking field in the response, distinct from the final answer field.75% similarVerifiedResearch has found that the chain-of-thought reasoning generated by models does not fully correspond to their actual internal computation processes, and may provide post-hoc explanations unrelated to the true decision-making path.75% similar
