Grok
xAI's assistant with real-time X data and cheap output tokens
Best for:real time datacost sensitiveagentscoding
Grok is xAI's assistant, built on the Grok 4.x line and wired into real-time X (Twitter) data. Grok 4.6 is the current flagship for agents and coding at 500K context, while the older Grok 4.3 is both cheaper and wider at 1M context — an unusual inversion worth checking before you default to the newest model.
