Elon Musk's AI startup, xAI, has launched its API, making its generative AI model, Grok, available for external use. The API currently offers a single "grok-beta" model, priced at $5 per million input tokens or $15 per million output tokens. While the API supports function calling and hints at vision models analyzing text and images, some users have reported issues with payment credits.
