Is Codex getting worse?

We look for the same downward movement across multiple reasoning efforts. One lower score can be ordinary benchmark variation, so the page only calls out a possible broad drop when at least two comparable efforts fall together.

Sometimes. A higher reasoning setting is not automatically better for every task. The effort comparison shows the latest measured score for each setting, and leaves a setting blank when no public result exists.

No. Juice is an observed runtime-budget signal. Capability scores come from coding-task results. A Juice change may tell us that a configuration changed, but it does not prove that coding quality improved or declined.
