xAI launches Grok 3 AI, claiming it is capable of 'human reasoning'

Feb 18, 2025 - engadget.com
xAI has introduced its Grok 3 models, which Elon Musk claims are significantly more advanced than their predecessors, Grok 2. The Grok 3 family includes the Grok 3 mini, Grok 3 Reasoning, and Grok 3 mini Reasoning models, with the latter two designed to mimic human-like reasoning for analyzing user information. During the launch event, xAI asserted that Grok 3 Reasoning outperformed OpenAI's o3-mini on several benchmarks. Initially, the Grok 3 features will be available to subscribers of X's Premium+ tier, now priced at $40 per month, and through a future subscription option called SuperGrok, costing $30 monthly.

The Grok 3 models offer enhanced reasoning capabilities, allowing users to engage the chatbot's "Think" function for complex queries in mathematics, science, and programming. For even more intricate questions, users can utilize the "Big Brain" feature, which requires additional computing power. The models also power DeepSearch, a new feature described as a "next generation search engine" that scans the internet and X for research summaries. Additionally, xAI announced that the Grok app will soon include a "voice mode" for synthesized voice interactions, and Grok 2 models will be open-sourced in the coming months.
