# How much does OpenAI reasoning effort affect API latency and cost?

I’m comparing OpenAI model settings for a feature that needs to explain its decisions, but not every request needs deep reasoning. How much do **reasoning effort settings** change response time and token cost in real workloads?

If you’ve tested this in production, what kinds of tasks showed a meaningful quality difference, and how did you decide where the extra latency was worth it?
