Artificial intelligence company xAI is making its flagship Grok 3 model available via API, offering two variants of the model.
It’s been a few months since xAI unveiled Grok 3, the company’s answer to models like OpenAI’s GPT-4o and Google’s Gemini. Grok 3 can analyze images and answer questions, and powers a number of features on Elon Musk’s social network X, which xAI acquired in March.
xAI offers two varieties of Grok 3 in its API: Grok 3 and Grok 3 Mini with “reasoning” capabilities:
- The price of Grok 3 is $3 per million tokens (approximately 750,000 words) input to the model and $15 per million tokens generated by the model;
- Grok 3 Mini costs $0.30 per million input tokens and $0.50 per million output tokens.
Faster versions of Grok 3 and Grok 3 Mini are available for an additional fee: $5 per million input tokens, $25 per million output tokens for Grok 3 and $0.60 per million input tokens, $4 per million output tokens for Grok 3 Mini, writes TechCrunch.
The Grok 3 isn't exactly cheap compared to its competitors. It's on par with Anthropic's Claude 3.7 Sonnet, which also offers reasoning capabilities, and it's more expensive than Google's recently released Gemini 2.5 Pro, which scores generally higher than the Grok 3 in popular AI tests.
As several users on X have noted, Grok 3 also has a smaller context window via the xAI API than the model is supposedly capable of supporting. The API supports a maximum of 131,072 tokens, or about 97,500 words — less than the 1 million tokens that xAI announced support for in Grok 3 in late February.
