TL;DR: Elon Musk's xAI has unveiled the Grok 3 AI model, claiming it outperforms competing products from OpenAI and DeepSeek. The company also announced plans to open-source Grok 2 later this year and has updated the Grok iOS and web apps with new capabilities. Additionally, xAI introduced Grok 3 Mini, a smaller, faster variant of the model that trades some accuracy for increased speed. During the Grok 3 announcement livestream on X, Elon Musk claimed the new model is 10 times more powerful and "an order of magnitude" more capable than its predecessor. Previously, Musk had promised that Grok 3 would be "scary smart," with advanced reasoning capabilities.The Grok 3 family includes Grok 3 Reasoning and Grok 3 Mini Reasoning, both designed to "think through" problems, similar to OpenAI's o3-mini and DeepSeek R1. These reasoning models fact-check their responses in real time to minimize inaccuracies, a common issue with AI systems like ChatGPT and Google Gemini.According to test data provided by xAI, Grok 3 Reasoning outperforms OpenAI's o3-mini-high in key benchmarks, including AIME 2025, a high school-level mathematics assessment. xAI emphasized that its latest reasoning models excel at answering math, science, and programming questions. Both models are available via the Grok app.According to xAI, the Grok app will soon receive a new feature called DeepSearch, similar to OpenAI's Deep Research. This tool will scan online sources, including X, to generate responses to various queries. Additionally, the app will introduce a voice mode with a synthesized voice, expected to roll out as early as next week.Grok 3 was reportedly trained on a supercomputer called Colossus, which utilizes more than 200,000 GPUs in a data center in Memphis, Tennessee. xAI claims that Colossus was built within six to eight months specifically to train the next-generation Grok model. // Related StoriesGrok 3 will initially be available in early access to X Premium+ subscribers. xAI is also introducing a new subscription package called SuperGrok, available through the Grok app and website. This premium tier includes advanced features such as enhanced reasoning, DeepSearch queries, and unlimited image generation. It is rumored to cost $30 per month or $300 per year.Musk also reiterated his commitment to open-sourcing older versions of Grok whenever a new iteration is fully rolled out. Following the launch of Grok 3, xAI plans to open-source Grok 2. According to Musk, the company will release Grok 2's source code to the public "in the coming months" once Grok 3 is "mature and stable."
