xAI Names Its Own New Model The Best It Has Built
xAI's developer docs price Grok 4.5 at $2 per million input tokens, $6 per million output, across a 500,000-token window.
- Grok 4.5 replaces prior models as xAI's default recommendation for both its Code and Chat APIs.
- The model handles images up to 20 megabytes each, with no stated cap on quantity.
- Grok 4's knowledge cutoff was November 2024; xAI's page states none for 4.5 itself.
Why it mattersThe only witness to Grok 4.5's superiority is the company that sells it.
