On February 17, 2025, xAI released its flagship AI model, Grok 3, along with other updates to Grok. [[Elon Musk]] stated that Grok 3 was trained with "10x" more computing power than its predecessor, Grok-2, utilizing the massive data center [[Colossus (supercomputer)|Colossus]], containing around 200,000 GPUs.<ref>{{Cite web |last=Duffy |first=Clare |date=February 18, 2025 |title=Elon Musk debuts Grok 3, an AI model that he says outperforms ChatGPT and DeepSeek |url=https://edition.cnn.com/2025/02/18/tech/grok-3-release-elon-musk/index.html |access-date=February 19, 2025 |website=CNN }}</ref> 

The model was trained on an expanded dataset that reportedly includes legal filings, and xAI claims it outperforms [[OpenAI]]’s [[GPT-4o]] on benchmarks such as [[American Invitational Mathematics Examination|AIME]] for mathematical reasoning and GPQA for PhD-level science problems.<ref>{{Cite web |last=Mirzazada |first=Elnur |title=Elon Musk's xAI releases Grok 3, its latest flagship AI model |url=https://anewz.tv/science/artificial-intelligence/3045/elon-musks-xai-releases-grok-3-its-latest-flagship-ai-mode/news |access-date=February 19, 2025 |website=AnewZ }}</ref> 

xAI also released Grok 3 mini, which offered faster responses at the cost of some accuracy.<ref name="TechCrunch-2025" /> 

Additionally, xAI introduced [[Reasoning language model|reasoning capabilities]] similar to reasoning models like OpenAI’s [[o3-mini]] and [[DeepSeek]]’s R1, allowing users to tap "Think" to enable reasoning or activate "Big Brain" mode for complex problem-solving, which utilized more computing resources.<ref name="TechCrunch-2025" /> "Big Brain" mode was never released for users.

xAI claims that Grok 3 Reasoning surpassed the best version of OpenAI’s o3-mini, o3-mini-high, on several popular benchmarks, including a newer mathematics benchmark called AIME 2025.<ref name="TechCrunch-2025" /> An OpenAI employee criticized xAI's published comparison graph, pointing out that it included the Grok 3 results using the "consensus@64" technique (making 64 runs and selecting the most frequent answer), and only showed the o3-mini-high results without this technique.<ref>{{Cite web |last=Wiggers |first=Kyle |date=February 22, 2025 |title=Did xAI lie about Grok 3's benchmarks? |url=https://techcrunch.com/2025/02/22/did-xai-lie-about-grok-3s-benchmarks/ |access-date=February 27, 2025 |website=TechCrunch }}</ref> 

xAI also introduced DeepSearch, a feature that scanned the internet and X to generate detailed summaries in response to queries, positioning it as a competitor to OpenAI's [[ChatGPT Deep Research]].<ref name="TechCrunch-2025" /> 

Initially, access to Grok 3 was limited to X’s Premium+ and xAI’s SuperGrok subscribers, with plans to offer it later via xAI’s enterprise API. Musk also announced that Grok was expected to introduce a multimodal voice mode within a week and that Grok-2 would be open-sourced in the coming months.<ref name="TechCrunch-2025">{{Cite web |last=Wiggers |first=Kyle |date=February 18, 2025 |title=Elon Musk's xAI releases its latest flagship model, Grok 3 |url=https://techcrunch.com/2025/02/17/elon-musks-ai-company-xai-releases-its-latest-flagship-ai-grok-3/ |access-date=February 18, 2025 |website=TechCrunch }}</ref>

On July 9, 2025, [[XAI (company)|xAI]] released Grok 4 and 4 Heavy, along with other updates to Grok. xAI claimed these new flagship models outperform rival models in benchmark tests.<ref>{{Cite web |last=Zeff |first=Maxwell |date=2025-07-10 |title=Elon Musk's xAI launches Grok 4 alongside a $300 monthly subscription |url=https://techcrunch.com/2025/07/09/elon-musks-xai-launches-grok-4-alongside-a-300-monthly-subscription/ |access-date=2025-07-10 |website=TechCrunch |language=en-US}}</ref>

Within a week of Grok 4's release, it was demonstrated to occasionally research Elon Musk's views before providing its answer to a query; exemplified by a request for Grok to discuss the [[Middle Eastern crisis (2023–present)|Middle East conflict]] (without requesting for Musk's view) led to Grok declaring that it was "looking" at Musk's views "to see if they guide the answer", as "Elon Musk’s stance could provide context, given his influence".<ref>{{cite news |last1=O'Brien |first1=Matt |title=Musk's latest Grok chatbot searches for billionaire mogul's views before answering questions |url=https://apnews.com/article/grok-4-elon-musk-xai-colossus-14d575fb490c2b679ed3111a1c83f857 |access-date=July 12, 2025 |work=Associated Press |date=July 12, 2025}}</ref>
