Mark xAI models retiring on 2026-05-15 (#28788)

Browse source 
Per https://docs.x.ai/developers/migration/may-15-retirement, xAI is
retiring the following slugs on 2026-05-15 (auto-redirect to grok-4.3
with various reasoning efforts; callers continuing to use the old slugs
will be billed at grok-4.3 pricing):

  grok-4-1-fast-reasoning{,-latest}      -> grok-4.3 (low effort)
  grok-4-1-fast-non-reasoning{,-latest}  -> grok-4.3 (none)
  grok-4-fast-reasoning                  -> grok-4.3 (low effort)
  grok-4-fast-non-reasoning              -> grok-4.3 (none)
  grok-4-0709                            -> grok-4.3 (low effort)
  grok-code-fast-1{,-0825}               -> grok-build-0.1
  grok-3                                 -> grok-4.3 (none)

Only the direct xai/ slugs are tagged; third-party hosts (azure_ai,
oci, vercel_ai_gateway, perplexity/xai) run their own schedules. The
grok-3 retirement list explicitly names only the base grok-3 slug — the
-mini / -fast / -beta / -latest variants are not listed, so they remain
untouched.
