Grok 4 by xAI was released on July 9, and it's surged ahead of competitors like DeepSeek and Claude at LMArena, a leaderboard for ranking generative AI models. However, these types of AI rankings don't factor in potential safety risks.

TechnologyAdvice's Grant Harvey provides a deep dive on Grok 4, the "new" model from Elon Musk's AI company xAI.

When Elon Musk’s xAI unveiled Grok 4, the bold claim was that it would be a “maximally truth-seeking” artificial intelligence, smarter than most PhDs and able to tackle society’s most pressing debates.

Grok 4 is a huge leap from Grok 3, but how good is it compared to other models in the market, such as Gemini 2.5 Pro? We now have answers, thanks to new independent benchmarks.

Just days after launch, Elon Musk’s Grok-4 is compromised by researchers using a stealthy blend of Echo Chamber and Crescendo techniques, exposing deep flaws in AI safety systems.

The stolen API key allows interaction with at least 52 large language AI models (LLMs) that are in development at Musk's xAI, many of these in turn used by the "Grok" AI available through the X social media platform.

When xAI launched Grok 4 last week, the company claimed the large language model outperformed several competitors on various benchmarks. However, the Grok

Researchers already jailbroke xAI's new Grok-4 model just two days after launch, using combined 'Echo Chamber' and 'Crescendo' attacks to bypass safety guardrails.

AI owner Elon Musk made some big claims about Grok’s capability, saying it was “better than PhD level in every subject.”
