Grok 3 Mini (xAI)
Yes — Grok 3 Mini is retired and no longer served by xAI, which has not published the exact shutdown date. The recommended replacement is Grok 4.3.
The small reasoning model of the Grok 3 generation, and the first xAI id that exposed its thinking trace, which made it briefly popular for debugging agent behaviour. It went before grok-3 itself did. The id is off the model list and its docs page 404s, with no retirement date left in xAI's documentation.
