Testing

ModelPilot

A public beta that turns one pasted Codex task into a recommended model and reasoning effort.

Problem
Users often do not know which Codex model and reasoning effort fit a task.
Current hypothesis
A single-paste transparent recommendation is useful enough to validate before building an automatic router.
Next decision
Measure whether real users follow the recommendation and come back to use the tool again.
