Grok is a neural network from Elon Musk's company xAI and a direct rival to ChatGPT and Claude. It answers questions, writes and analyses text, works with code and draws images from a description — all in one conversation.
The family's defining feature is the size of its context: the larger models hold up to two million tokens, which is thousands of pages at once. Grok searches the web and leans on what it finds, so it answers questions about recent events and not only about what was in its training data. The tone is noticeably freer than with competitors: the model dodges the topic with formal caveats less often.
Every Grok model is available in GPTunneL — worldwide, without a VPN, with one balance and billing for the tokens you actually spend.
