Grok 4.7 joins xAI's model list at the same price and context as Grok 4.6

xAI's model list now includes grok-4.7⁠[1]. Its context window is 500k tokens, the same as grok-4.6⁠[1].

The price per million tokens matches grok-4.6 too: for prompts under 200k tokens, $2 input, $0.50 cached input and $6 output⁠[1]. At 200k tokens or more it is $4, $1 and $12, so every rate doubles⁠[1].

On grok-4.7 and grok-4.6, cached input is a quarter of the input price⁠[1]. grok-4.5 has the same input and output rates, and only its cached input is cheaper, at $0.30⁠[1].

The models on the list with a 500k context are grok-4.7, grok-4.6 and grok-4.5⁠[1]. grok-4.3 and the grok-4.20 models hold 1 million tokens and stay cheaper, at $1.25 input and $2.50 output⁠[1].

grok-build-0.1 holds 256k tokens at $1 input and $2 output⁠[1]. On every model, the rates double once a prompt reaches 200k tokens⁠[1].
