xAI, Elon Musk's AI company, has launched an API for its flagship Grok 3 model, . This API provides access to both Grok 3 and Grok 3 Mini, which are designed to analyze images and respond to questions, enhancing features on Musk's social network, X.

The API offers two pricing tiers: Grok 3 is priced at $3 per million input tokens and $15 per million output tokens, while Grok 3 Mini costs $0.30 per million input tokens and $0.50 per million output tokens. Faster versions are available at a premium.

Despite its capabilities, Grok 3's API has a smaller context window than initially claimed, maxing out at 131,072 tokens. This launch follows xAI's acquisition of X and aims to position Grok 3 as a competitor to models like OpenAI's GPT-4o and Google's Gemini.
