Elon Musk’s AI company, xAI, has launched an API for its Grok 3 model, despite being countersued by OpenAI.
Several months after introducing Grok 3, designed to compete with models like OpenAI’s GPT-4o and Google’s Gemini, xAI is making it available through the new API. Grok 3 can analyze images and answer questions, powering multiple features on Musk’s social network, X, which was acquired by xAI in March.
The API offers two versions: Grok 3 and Grok 3 Mini, both equipped with reasoning capabilities. Grok 3 is priced at $3 per million tokens for input and $15 per million for output, while Grok 3 Mini costs $0.30 per million input tokens and $0.50 for output.

Faster versions are available at higher rates: $5 per million input and $25 per million output for Grok 3, and $0.60 per million input and $4 per million output for Grok 3 Mini.
Grok 3’s pricing is comparable to Anthropic’s Claude 3.7 Sonnet, though it is higher than Google’s Gemini 2.5 Pro, which generally outperforms Grok 3 in AI benchmarks. Additionally, xAI has faced criticism for potentially misleading benchmark reports.
Users on X have noted that Grok 3’s API has a smaller context window than advertised, maxing out at 131,072 tokens (about 97,500 words), rather than the claimed 1 million tokens.
When Musk introduced Grok two years ago, he characterized it as edgy and unfiltered, willing to tackle controversial topics other AIs avoid. While Grok models prior to Grok 3 were cautious on political issues, Musk has attributed this behavior to their training data and has promised to make Grok more politically neutral. However, the effectiveness of this change remains uncertain.
