The July 24 migration deadline has passed, so the forward-looking alert is historical

The original record described a pre-deadline migration risk and cannot remain a current negative claim after the cutoff. Current alias targets and available model IDs require fresh verification against the live API model list.

Production calls should still pin explicit model IDs, record the served version, and refresh the current model list before deployment.

Verified limitations

Usage boundaries

  • The official API update is a public beta.
  • The 2026-07-31 update does not state that the re-post-trained 0731 weights were released; the earlier V4 Flash base weights do not prove this checkpoint is open.
