Pricing Details

xAILaunched August 12, 2026 on Grok 4.5's exact rate card except for one line. Input $2.00 and output $6.00 are identical to Grok 4.5, as is the 500K context and the 200K threshold; cached input is $0.50/1M against Grok 4.5's $0.30, a 67% increase that takes the cache discount from 85% off to 75% off. Above 200K prompt tokens every rate doubles to $4.00/$12.00 (cached $1.00) and xAI bills the higher rate across all tokens in the request, not just the overage. Cached tokens count toward the 200K trigger, so a long cached prefix can cross the cliff on its own. Batch: none, and not merely 0% - xAI's batch docs state grok-4.6 and grok-4.5 requests are rejected. Priority Processing is a flat 2x on all token types applied after the cache discount, with no separate slug; xAI's announcement mentions a "fast variant" at twice the price without naming it, and Priority Processing is the only 2x option in the docs. Server-side tools: web/X search $5 per 1,000 calls. New xhigh reasoning effort. Knowledge cutoff February 1, 2026. No published aliases; grok-build-latest still resolves to Grok 4.5. No cache TTL published. maxOutput 16384 is not a provider figure: xAI states "no text output limit" for this model, so the number here is carried for schema consistency with the rest of the Grok line. Artificial Analysis Intelligence Index 60.92 (#6), Terminal-Bench 2.1 88.39, cost per index task $0.8367 against Grok 4.5's $0.3601. Estimated tokens (different tokenizer).
