Compared with the 2026-06-29 snapshot, the 2026-06-30 scan recorded 81 new listings, 155 regressions, and 6,150 parked unknown transitions.
Representative changes: ai21 jamba 1 5 large model from ai21-labs (version 1) was no longer listed in centralus; ai21 jamba 1 5 mini model from ai21-labs (version 1) was no longer listed in centralus; ai21 jamba instruct model from ai21-labs (version 1) was no longer listed in centralus.
What this means: Review the 155 regressions against existing regional targets and fallbacks first; treat the 81 new listings as options to validate. These are read-only catalog/list signals, not quota, capacity, or deployment results. Zero new delistings does not establish recovery of earlier missing listings.
7-day context (2026-06-24 to 2026-06-30): across 7 recorded scans, there were 1,745 new listings and 1,146 regressions. New listings led on 3 scans; regressions led on 4.
