Grok 4.7 arrives on the xAI API

TL;DR

• xAI's model docs list Grok 4.7 as the model it recommends for code and chat, with a 500k context window and a knowledge cutoff of May 2026.
• Under 200k prompt tokens it costs $2 per million input, $0.50 cached and $6 output; at 200k and above, $4, $1 and $12.
• The price and context are the same as Grok 4.6, so the change for an existing app is the model name.
