Elon Musk unveiled the newest edition of xAI's flagship AI model, Grok, late Wednesday night in a livestream video that touted Grok 4's prowess at topping benchmark scores. Why it matters: xAI is in an accelerating race with OpenAI,

AI, made a splash with the release of Grok 4, and the announcement of a new ultra-premium subscription tier, SuperGrok Heavy.

Finnish e-motor startup Donut Lab raised €25 million ($29.2 million) in a seed funding round led by Risto Siilasmaa, the founder of cybersecurity company WithSecure (formerly F-Secure). Risto has also joined Donut Lab’s board.

As Grok fired off replies on X praising Hitler, the chatbot's parent company also recently got permission to emit 97 tons of carbon monoxide per year to keep it running.

XAI’s Grok 4 AI chatbot launched Wednesday appears to consult Elon Musk’s views when asked its opinion on some controversial matters.

The ‘maximally truth-seeking’ chatbot checks Musk’s stance on topics around Israel and Palestine, abortion, and immigration.

Tesla is set to incorporate the startup xAI's AI chatbot, Grok, into its electric vehicles (EVs), a move announced by Elon Musk on X.

Grok’s training, including how the model is told to respond, and the material it aggregates likely played a role in its spew of hate speech.
