Some of the key features of the xAI API include:
- Function calling: enables Grok models to connect with external tools such as databases and search engines
- Vision models: capable of analyzing both text and images, although these features are not yet live
- Limited pricing options: $5 per million input tokens or $15 per million output tokens
- Technical issues: users have reported encountering problems paying for usage credits
- Limited functionality: the API currently only offers a single model, "grok-beta"
