Full-window policy and null output

A full window does not mean “always send a huge prompt”; it means do not silently shrink the official window with a local guard.

Big idea

A full window does not mean “always send a huge prompt”; it means do not silently shrink the official window with a local guard.

Think of it as… Think of a road with its real capacity sign: do not narrow the lane as a precaution and then call it vehicle capacity. The analogy breaks because models also have output ceilings..

Under the hood

Every text route uses targetInputUtilization=1.0, official source, and no small fallback. kimi-k3 targets 1048576; GPT-5.6 luna/sol/terra target 272000. output null means no unpublished ceiling was invented.

Predict before revealing

What does output null mean in this policy?

Null prevents an unsupported local output ceiling; it does not disable model output.

Worked example
1Inspect global targetInputUtilization=1.0.
2Compare K3 1048576 with GPT-5.6 272000.
3Confirm no max_tokens override is added to K3.

What does output null mean in this policy?

Null prevents an unsupported local output ceiling; it does not disable model output.

Ask which boundary you would prove next; the next lesson narrows a different operational risk.
