AI Gateway
xAI's lightweight model that thinks before responding. Great for simple or logic-based tasks that do not require deep domain knowledge. The raw thinking traces are accessible. The fast model variant is served on faster infrastructure, offering response times that are significantly faster than the standard. The increased speed comes at a higher cost per output token.
import { streamText } from 'ai'
const result = streamText({ model: 'xai/grok-3-mini-fast', prompt: 'Why is the sky blue?'})
