Released September 21, 2026 (xAI release notes: 'Grok 4.7 … is now available on the xAI API as grok-4.7. It has a 500k context window, text and image inputs with text-only output, and no text output limit. Pricing is $2 / $0.50 / $6 per 1M tokens (input / cached input / output) below 200k prompt tokens, and $4 / $1 / $12 above.'). Read by hand on 2026-09-22 from xAI's pricing page, table row 'grok-4.7 Long context ≥ 200k tokens | 500k | $2.00 | $0.50 | $6.00 | $4.00 | $1.00 | $12.00'; the model page prints 'Context window 500,000' and 'Batch API Not supported'. Not in the table: 'Grok 4.7 Fast', the same model at twice the token rates, 'available only through Cursor and Grok Build; it is not available on the public xAI API', and the US regional endpoint at 1.1x the global rates. On 2026-09-22 xAI's own endpoint on OpenRouter listed it at $1.60 / $4.80 (cached $0.40), 0.8x this page's list price, with no discount flagged.
