Grok 4.5
xAI's July 2026 flagship at $2 input / $6 output per 1M tokens — notable for keeping a 3:1 output-to-input ratio where most rivals charge 5-6x, which makes it materially cheaper than headline comparisons suggest on generation-heavy work. 500K context, Artificial Analysis Intelligence Index 54. Watch three things: prompts over 200K tokens double in price, Grok 4.5 is excluded from the batch discount that applies to Grok 4.3, and tools bill separately (Web/X Search and Code Execution at $5 per 1,000 calls, File Attachments at $10 per 1,000). Cached input is quoted between $0.30 and $0.50 depending on source — verify in the console before modelling costs.
