Does Grok support image analysis?

Yes, the grok-2-vision model is specifically designed for vision tasks including image analysis, chart interpretation, and screenshot processing.

How can I reduce API costs when using xAI models?

You can reduce costs by using Grok-3-mini for simple tasks, leveraging token caching (which is 75% cheaper), and batching similar requests into a single prompt.

What is the context window for Grok-4-1-fast?

Grok-4-1-fast features a 2 million token context window, which is equivalent to approximately 6,000 pages of text or 50 hours of audio.

Which Grok model is best for tool calling?

Grok-4-1-fast is the recommended model for tool calling and agentic workflows due to its optimized performance and massive 2M token context window.

Can Grok models perform real-time searches on X (Twitter)?

Yes, models like Grok-4-1-fast are optimized for real-time search and sentiment analysis on the X platform via built-in tool calling.
