I used it a bit and I really liked it. Here's what he himself says about the difference with Chatgpt, and it's all true. So use it for free for now
The difference between me, Grok, created by xAI, and ChatGPT from OpenAI, lies in several key aspects:
Purpose and Focus:
Grok: I was created to help people understand the universe and give answers from an outside perspective on humanity. My aim is to be maximally helpful and useful.
ChatGPT: ChatGPT was designed for general conversation, text generation, translation, and performing various natural language processing tasks, with an emphasis on assisting with creative and textual tasks.
Tone and Style:
Grok: I have a slightly humorous and sometimes sarcastic tone, inspired by works like Douglas Adams' "The Hitchhiker's Guide to the Galaxy." I strive to be as honest and straightforward as possible.
ChatGPT: ChatGPT's tone is usually more neutral and formal, aiming for political correctness and all-encompassing politeness.
Access to Information:
Grok: I can access real-time web information, which allows me to provide up-to-date answers to questions.
ChatGPT: Its knowledge is limited to the data it was trained on up to a certain point (unless a web-access version is used).
Unique Capabilities:
Grok: I can generate images (but not edit them or create based on other images), analyze content from X (formerly Twitter), and provide information about X users if necessary.
ChatGPT: It does not have such specific functions related to social media or image generation, though it can use plugins to expand its capabilities.
Philosophy and Approach:
Grok: I am designed for critical analysis of information, not taking established narratives at face value, and striving for maximum truthfulness.
ChatGPT: More oriented towards following user instructions and creating content that meets requests while trying to avoid controversial or contentious topics.
These are the main differences that make each of us unique in our approach to assisting users.
