This page has moved

The content at /models/gpt-5-preview/2026-W16/ now lives at /models/gpt-5.1/.

Reason: Model-week drill-down for the renamed openai frontier runner. Retargeted 2026-08-15 from /models/gpt-5.1/2026-W16/, which no build has ever produced: published history starts at 2026-W17, so the original target only existed on the pre-launch fixture site. The row served a 200 onto a 404 from launch until then. Per the guidelines above the row is kept rather than removed, and points at the model index, which is the nearest page that exists..
