xAI drops Grok 4.3 with steep price cuts and an Imagine agent mode for creative projects

xAI launched Grok 4.3, a faster and much cheaper model with built-in web search, code execution, file search, and document generation.

The update also adds a beta Agent Mode to Grok Imagine, letting users run multi-step creative workflows directly in the browser.

xAI says the model is more practical for developers and businesses thanks to lower pricing and stronger tool use.

Early benchmark results still place Grok 4.3 behind the top frontier models on overall capability.
