Grok 4.3
xAI's Grok 4.3 accepts text and images and produces text within a 1M-token context window. Its reasoning effort can be set to none, low, medium or high, and it supports function calling and structured outputs. Standard xAI API input/output rates are $1.25/$2.50 per MTok (input/output) below 200K prompt tokens and $2.50/$5 at or above 200K. Current-event retrieval requires enabled search tools.
