What the User Actually Sees · 1/2
Visible thinking versus silent effort
From a user's perspective, test-time compute shows up in one of two broad ways. Some systems visibly display the model's reasoning process, a thinking or intermediate output the user can watch or expand, before the final answer appears. This makes the extra effort tangible: you can see the model working through sub-steps, and the wait itself signals that more computation is happening.
Other systems apply extra compute silently, running additional reasoning, sampling, or verification behind the scenes without exposing the intermediate steps to the user at all. In that case, the only signal a user gets is indirect, typically a longer response time, with the underlying reasoning process hidden from view.
