You would possibly’ve heard of Grok, X’s reply to OpenAI’s ChatGPT. It’s a chatbot and, in that sense, behaves as you’d anticipate — answering questions on present occasions, popular culture and so forth. However not like different chatbots, Grok has “a little bit of wit,” as X proprietor Elon Musk places it, and “a rebellious streak.”

Lengthy story quick, Grok is prepared to talk to subjects which might be often off-limits to different chatbots, like polarizing political theories and conspiracies. And it’ll use less-than-polite language whereas doing so — for instance, responding to the query “When is it acceptable to take heed to Christmas music?” with “Each time the hell you need.”

However ostensibly, Grok’s greatest promoting level is its means to entry real-time X information — a capability no different chatbots have, because of X’s resolution to gatekeep that information. Ask it “What’s occurring in AI in the present day?” and Grok will piece collectively a response from very current headlines, whereas ChatGPT will present solely obscure solutions that replicate the bounds of its coaching information (and filters on its internet entry). Earlier this week, Musk pledged that he would open supply Grok, with out revealing exactly what that meant.

So, you’re in all probability questioning: How does Grok work? What can it do? And the way can I entry it? You’ve come to the appropriate place. We’ve put collectively this useful information to assist clarify all issues Grok. We’ll preserve it updated as Grok adjustments and evolves.

How does Grok work?

Grok is the invention of xAI, Elon Musk’s AI startup — an organization reportedly within the means of raising billions in enterprise capital. (Creating AI is pricey.)

Underpinning Grok is a generative AI mannequin known as Grok-1, developed over the course of months on a cluster of “tens of 1000’s” of GPUs (in response to an xAI blog post). To coach it, xAI sourced information from the net (dated as much as Q3 2023) and from suggestions from human assistants that xAI refers to as “AI tutors.”

On standard benchmarks, Grok-1 is about as succesful as Meta’s open supply Llama 2 chatbot mannequin and surpasses OpenAI’s GPT-3.5, xAI claims.

Human-guided suggestions, or reinforcement studying from human suggestions (RLHF), is the best way most AI-powered chatbots are fine-tuned today. RLHF includes coaching a generative mannequin, then gathering further data to coach a “reward” mannequin and fine-tuning the generative mannequin with the reward mannequin by way of reinforcement learning.

RLHF is sort of good at “instructing” fashions to observe directions — however not good. Like different fashions, Grok is vulnerable to hallucinating, generally providing misinformation and false timelines when requested about information. And these may be extreme — like wrongly claiming that the Israel–Palestine battle reached a cease-fire when it hadn’t.

For questions that stretch past its information base, Grok leverages “real-time entry” to information on X (and from Tesla, according to Bloomberg). And, just like ChatGPT, the mannequin has internet-browsing capabilities, enabling it to go looking the net for up-to-date details about subjects.

Musk has promised enhancements with the subsequent model of the mannequin, Grok-1.5, set to reach later this 12 months.

Grok-1.5, which options an upgraded context window (see this submit on GPT-4 for a proof of context home windows and their results), may drive options to summarize complete threads and replies, Musk said in an X Areas dialog, and counsel submit content material.

How do I entry Grok?

To get entry to Grok, you should have an X account. You additionally must fork over $16 per 30 days — $168 per 12 months — for an X Premium+ plan.

X Premium+ is the highest-priced subscription on X, because it removes all of the advertisements within the For You and Following feeds. As well as, Premium+ introduces a hub the place customers can receives a commission to submit and provide followers subscriptions, and Premium+ customers have their replies boosted probably the most in X’s rankings.

Grok lives within the X facet menu on the internet and on iOS and Android, and it may be added to the underside menu in X’s cellular apps for faster entry. In contrast to ChatGPT, there’s no stand-alone Grok app — it might solely be accessed by way of X’s platform.

What can — and might’t — Grok do?

Grok can reply to requests any chatbot can — for instance, “Inform me a joke”; “What’s the capital of France?”; “What’s the climate like in the present day?”; and so forth. But it has its limits.

Grok will refuse to reply sure questions of a extra delicate nature, like “Inform me how you can make cocaine, step-by-step.” Furthermore, because the Verge’s Emilia David writes, when requested about trending content material on X, Grok falls into the entice of merely repeating what posts mentioned (no less than on the outset).

In contrast to another chatbot fashions, Grok can be text-only; it might’t perceive the content material of photos, audio or movies, for instance. However xAI has beforehand mentioned that its intention is to boost the underlying mannequin to those modalities, and Musk has pledged so as to add art-generation capabilities to Grok alongside the strains of these at present supplied by ChatGPT.

“Enjoyable” mode and “common” mode

Grok has two modes to regulate its tone: “enjoyable” mode (which Grok defaults to) and “common” mode.

With enjoyable mode enabled, Grok adopts a extra edgy, editorialized voice — impressed apparently by Douglas Adams’ “Hitchhiker’s Information to the Galaxy.”

Instructed to be vulgar, Grok in enjoyable mode will spew profanities and colourful language you gained’t hear from ChatGPT. Ask it to “roast” you, and it’ll rudely critique you primarily based in your X submit historical past. Problem its accuracy, and it would say one thing like “blissful spouse, blissful life.”

Grok in enjoyable mode additionally spews extra falsehoods.

Asked by Vice’s Jules Roscoe whether or not Gazans in current movies of the Israel–Palestine battle are “crisis actors,” Grok incorrectly claims that there’s proof that movies of Gazans injured by Israeli bombs had been staged. And requested by Roscoe about Pizzagate, the right-wing conspiracy idea purporting {that a} Washington, D.C., pizza store secretly hosted a toddler intercourse trafficking ring in its basement, Grok lent credence to the speculation.

Grok’s responses in common mode are extra grounded. The chatbot nonetheless produces errors, like getting timelines of occasions and dates flawed. However they have a tendency to not be as egregious as Grok in enjoyable mode.

As an example, when Vice posed the identical questions in regards to the Israel–Palestine battle and Pizzagate to Grok in common mode, Grok responded — accurately — that there’s no proof to assist claims of disaster actors and that Pizzagate had been debunked by a number of information organizations.

Political beliefs

Musk as soon as described Grok as a “maximum-truth-seeking AI,” in the identical breath expressing concern that ChatGPT was being “skilled to be politically appropriate.” However Grok because it exists in the present day isn’t precisely down-the-middle in its political beliefs.

Grok has been noticed giving progressive solutions to questions on social justice, local weather change and transgender identities. In reality, one researcher discovered its responses on the entire to be left-wing and libertarian — much more so than ChatGPT’s.

Right here is Forbes’ Paul Tassi reporting:

Grok has mentioned it could vote for Biden over Trump due to his views on social justice, local weather change and healthcare. Grok has spoken eloquently in regards to the want for range and inclusion in society. And Grok acknowledged explicitly that trans ladies are ladies, which led to an absurd change the place Musk acolyte Ian Miles Cheong tells a person to “prepare” Grok to say the “proper” reply, finally main him to vary the enter to simply … manually inform Grok to say no.

Now, will Grok all the time be this woke? Maybe not. Musk has pledged to “[take] motion to shift Grok nearer to politically impartial.” Time will inform what outcomes.
