Eight Grok models retired at once: grok-4-1-fast, grok-4-fast, grok-4-0709, grok-code-fast-1, grok-3, and grok-imagine-image-pro. xAI silently redirected all retired slugs to grok-4.3 — meaning developers' bills and output quality changed without code changes or warnings. A masterclass in how NOT to handle deprecation.
