Elon Musk’s AI firm, xAI, launched its newest flagship AI mannequin, Grok 3, late Monday evening, together with new capabilities within the Grok apps for iOS and the online.
Grok, xAI’s reply to fashions like OpenAI’s GPT-4o and Google’s Gemini, can analyze photographs and reply to questions, and powers a variety of options on Musk’s social community, X. Grok 3, which has been in improvement for a number of months, was optimistically slated for launch in 2024, however missed that deadline.
Monday’s is an bold launch.
xAI has been utilizing an unlimited information middle in Memphis — an information middle containing round 200,000 GPUs — to coach Grok 3. In a post on X, Musk claimed that Grok 3 was developed with “10x” extra computing than Grok 2, its predecessor, and with an expanded coaching information set that ostensibly contains filings from court cases.
“Grok 3 is an order of magnitude extra succesful than Grok 2,” Musk mentioned throughout a live-streamed presentation Monday. “[It’s a] maximally truth-seeking AI, even when that fact is typically at odds with what’s politically right.”
Grok 3 is a household of fashions, to be exact — not only one. A smaller model of Grok 3, Grok 3 mini, responds to questions extra shortly at the price of some accuracy. Not all fashions can be found as of but (and a few are in beta), however the rollout begins Monday.
xAI claims that Grok 3 beats GPT-4o on benchmarks together with AIME, which evaluates a mannequin’s efficiency on a sampling of math questions, and GPQA, which assesses fashions utilizing PhD-level physics, biology, and chemistry issues. An early model of Grok 3 additionally scored competitively in Chatbot Arena, a crowdsourced check that pits completely different AI fashions in opposition to one another and has customers vote on their most well-liked responses, based on xAI.
Two variations of Grok 3, Grok 3 Reasoning and Grok 3 mini Reasoning, can fastidiously “assume by way of” issues, just like “reasoning” fashions like OpenAI’s o3-mini and Chinese language AI firm DeepSeek’s R1. Reasoning fashions totally fact-check themselves earlier than giving out outcomes, which helps them avoid some of the pitfalls that usually journey up fashions.
xAI claims that Grok 3 Reasoning surpasses the very best model of o3-mini — o3-mini-high — on a number of in style benchmarks, together with a more recent arithmetic benchmark known as AIME 2025.
The reasoning fashions could be accessed through the Grok app. Customers can ask Grok 3 to “Suppose,” or — for tougher queries — leverage “Huge Mind” mode for reasoning that employs further computing. xAI describes the reasoning fashions as finest fitted to mathematics-, science-, and programming-related questions.
Musk mentioned that, within the Grok app, among the reasoning fashions’ “ideas” are obscured to forestall distillation, a technique utilized by AI mannequin builders to extract data from one other mannequin. Lately, DeepSeek was accused of distilling OpenAI’s models to create its personal.
Grok’s reasoning fashions underpin a brand new function within the Grok app known as DeepSearch, xAI’s reply to AI-powered “deep analysis” instruments like OpenAI’s deep research. DeepSearch scans the web and X to research data and ship an summary in response to a query.
Subscribers to X’s Premium+ tier will get Grok 3 first, and different options are gated behind a brand new plan xAI’s calling SuperGrok. Priced at $30 monthly or $300 per 12 months, SuperGrok unlocks further reasoning and DeepSearch queries, and throws in limitless picture era.
Sooner or later — as quickly as a couple of week from now — the Grok app will achieve a “voice mode,” Musk mentioned, which can give Grok fashions a synthesized voice. A couple of weeks later, the Grok 3 fashions will arrive in xAI’s enterprise API, together with the DeepSearch function. A couple of months after that, xAI will open-source Grok 2, Musk mentioned.
“Our common strategy is that we are going to open-source the final model [of Grok] when the following model is totally out,” Musk mentioned. “When Grok 3 is mature and secure, which might be inside a couple of months, then we’ll open-source Grok 2.”
When Musk introduced Grok roughly two years in the past, he pitched the AI as edgy, unfiltered, and anti-“woke” — on the whole, prepared to reply controversial questions different AI methods gained’t. He delivered on a few of that promise. Instructed to be vulgar, for instance, Grok and Grok 2 would fortunately oblige, spewing colourful language you doubtless wouldn’t hear from ChatGPT.
However Grok fashions previous to Grok 3 hedged on political topics and gained’t cross certain boundaries. In actual fact, one study discovered that Grok leaned to the political left on subjects like transgender rights, range packages, and inequality.
Musk has blamed the conduct on Grok’s coaching information — public net pages — and pledged to “shift Grok nearer to politically impartial.” It’s not clear but whether or not xAI achieved that purpose.
