What changed with Grok 4.6
xAI released Grok 4.6 on August 12, 2026, less than a month after Grok 4.5. It focuses on long-running agents and on interactive and visual work, and xAI says it verifies its own output more often on longer tasks.
The docs list a 500k-token context window, text and image input, and text output. Pricing is $2 input and $6 output per 1M tokens below 200k prompt tokens, doubling above that threshold. It is available in Cursor, Grok Build, the xAI API, and partners such as OpenRouter, Vercel, and Cloudflare.
