Elon Musk’s AI company, xAI, launches an API for Grok 3
xAI has made Grok 3 and Grok 3 Mini with 'reasoning' capabilities available via API. Grok 3 is priced at $3 per million input tokens and $15 per million output tokens. xAI has been accused of being misleading in its benchmark reporting for Grok 3 and several users on X have pointed out that Grok 3 via xAI's API has a smaller context window than advertised - the API maxes out at 131,072 tokens.
