• –Flagship intervals have reportedly narrowed from 37 days in 2023 to 17 days in 2026.

• –Rapid model turnover creates leverage in pricing and procurement, but makes benchmark snapshots stale quickly.
• –Faster shipping also compresses safety testing, migration planning, and incident-response windows.
