Grok 4.6
xAI's current model — built for long-running agents and coding
Verdict
Released August 12, 2026, an agent- and coding-focused upgrade over Grok 4.5 rather than a context or pricing change — same 500K context, same $2/$6 short-context rate. The real change is sustained multi-step task performance. Watch the long-context pricing: past 200K tokens, input, cached input, and output all double for the entire request, not just the overage.
