Reasoning Effort
A model setting that trades latency and cost for more or less internal reasoning before producing an answer.
Plain English
You can ask the model to think lightly for easy work or spend more effort on hard work.
Example
A coding assistant uses low reasoning effort for a quick rename and high effort for a failing distributed-systems test.
Why it matters
Reasoning effort makes inference-time quality, cost, and speed a product-level control rather than a hidden model behavior.
