Nearly four months ago, Elon Musk founded xAI with the grand aim of building a “maximally curious” and “truth-seeking” AI model that would be interested in humanity and therefore predisposed to help it survive. xAI promised more details within weeks, but kept silent until this past weekend, when it released an early version of its AI to a small group of testers.

The chatbot is called Grok, and xAI says it’s “modeled after The Hitchhiker’s Guide to the Galaxy, which was an encyclopedia of sorts in Douglas Adams’s radio-play, novel, and TV series of the same name. (A little confusingly, the term “grok”—i.e. to truly understand something—comes from a different science fiction novel, Robert Heinlein’s Stranger in a Strange Land.)

We already knew that xAI’s model would be trained on X posts, but it turns out that the bond between the two supposedly separate companies will be much closer. Although it will also be a standalone product at some point, Grok will start out as a bonus feature for X’s highest subscription tier, the $16-per-month Premium+. Only X’s verified users will be able to join the early access program. X will also provide Grok with “real-time knowledge of the world,” which Musk claims gives it an advantage over its rivals—results tbd, given the amount of misinformation on X.

The first screenshots of Grok’s responses demonstrate that the AI will be vulgar if asked and can spout strong opinions about scooping bagels. Musk said it “is designed to have a little humor in its responses” and “loves sarcasm. I have no idea who could have guided it this way.” “Please don’t use it if you hate humor!” winks xAI with powerful “You don’t have to be crazy to work here but it helps!” vibes. Whether or not Grok amuses you probably depends on how funny you find Musk himself.

So who’s it for? There’s certainly nothing for business users to see here just yet. Musk fans may be tempted by the prospect of chatting to an AI that’s reminiscent of their hero, but I’d be surprised if Grok turned out to be X’s subscription-driving savior—there are just so many other chatbot options out there. X Premium+ is cheaper than ChatGPT Plus, which costs $20 per month, but ChatGPT also has a popular free tier, and OpenAI sponsor Microsoft also offers many of GPT-4’s cutting-edge features for free in Bing Chat.

OpenAI is reportedly even about to make it possible to create custom chatbots and share them through a marketplace, which sounds like a smart ecosystem play that could help the company stay ahead in the genAI game. So people will soon be able to make or buy other Snark-o-bot 3000s, if that’s what they’re after.

Grok-1’s appearance certainly shows a healthy pace of development at xAI. On the technical side, the company said in a statement that it outperformed OpenAI’s GPT-3.5 but still lagged GPT-4. That’s not bad, given that Grok has only had a couple months’ training, using less compute than OpenAI throws at its model—xAI is aiming for high efficiency and may yet achieve it.

But it is awfully strange to see xAI first demonstrate its safe-AI work by releasing a sarcastic chatbot with what the company calls “a rebellious streak.” Sure, Grok’s rivals may be annoyingly anodyne and prone to playing it safe, but there’s a reason for that.
