Which Grok model is best for tool calling and agents?

Grok-4-1-fast is the recommended choice for tool calling and agentic workflows due to its optimized performance, 2 million token context window, and competitive pricing.

What is the maximum context window for Grok models?

Grok-4-1-fast offers the largest context window at 2 million tokens, which is equivalent to roughly 6,000 pages of text or 50 hours of audio.

How can I reduce API costs when using xAI models?

You can optimize costs by using Grok-3-mini for simple tasks, leveraging token caching for a 75% discount, and batching similar requests to minimize overhead.

Does Grok support image analysis and vision?

Yes, Grok-2-vision is the specialized model for image analysis, charts, and screenshots, offering a 32K context window for visual tasks.
