EstimateBetween 16 Oct 2026 and 3 Nov 2026
From the last 12 gaps between OpenAI releases. Gaps of 1 day or less are left out, because that much time has already passed. The window covers the middle 80% of the gaps that are left.
How often windows like this were right: 46 of 62 times for OpenAI, 315 of 437 times (72%) across all labs, replaying each lab's past releases. A window aims for 8 in 10.
