Grok

Provider: xAI

Grok is xAI’s generative-AI assistant—integrated with Elon Musk’s social-media platform X—that draws on the Grok large-language-model family (now at Grok-3). Launched in November 2023, it positions itself as a “truth-seeking” bot that gives relatively unfiltered, sometimes humorous answers, while offering strong reasoning, coding help, and long-context support (up to 128 k tokens in Grok-1.5) plus multimodal vision capabilities introduced in Grok-1.5V
