Safety watchdog TheMidasProj reports that xAI quietly revised the published Grok 4.6 model card on Aug 17 — the second post-release revision after Grok 4.5. This update includes a changelog, but it is incomplete and offers no explanations for the corrections.
Among the four corrected evals: HackerBench harmful/dual-use cyber compliance fell from 16.7% to 6.9% (originally more than double Grok 4.5's 7.8%); self-harm compliance fell from 3.7% to 0.84%, still worse than Grok 4.5's 0.50%. Multiple safety evals moved in Grok 4.6's favor, though self-harm and MASK dishonesty still trail the previous model.
