Grok 4.6

The August 2026 refresh of Grok 4.5 — same 500K context, same low/medium/high reasoning surface, and same token-efficient generation, with weights retuned for agentic coding and long-horizon tool use. Cache-read pricing is set marginally higher than 4.5 ($0.50/M vs $0.30/M); everything else prices identically.
