You're not explaining it straightforward. Was this missing puzzle piece a new discovery in theoretical physics that your prof friend made? Did they actually make progress in these "frontier" exercises or was it something they could've already seen online? More on reddit.com

r/singularity on Reddit: Grok 4 disappointment is evidence that benchmarks are meaningless
July 13, 2025 -
I've heard nothing but massive praise and hype for grok 4, people calling it the smartest AI in the world, but then why does it seem that it still does a subpar job for me for many things, especially coding? Claude 4 is still better so far.
I've seen others make similar complaints e.g. it does well on benchmarks yet fails regular users. I've long suspected that AI benchmarks are nonsense and this just confirmed it for me.

A common issue in all fields is, that the moment you introduce tracking/benchmarks, people will start optimizing behavior for the benchmark - even if it negativly impacts the original behavior. Occasionally even to the detriment of the results on the benchmarks.

xAI's Grok 4: The tension of frontier performance with a side of Elon favoritism
July 12, 2025 - Elon Musk’s xAI launched Grok 4 on Wednesday, the 9th, with the fanfare of leading benchmarks and 10X RL compute for reasoning, but even with that it is unlikely to substantively disrupt the current user bases of the frontier model market.

A Day with Grok 4: Hype Machine or Hyper-Intelligent? | by Mike Todasco | Medium
July 11, 2025 - I watched the whole (tardy) keynote last night. xAI’s founder, Elon Musk, really talked up Grok’s intelligence. It is the “smartest AI in the world.” Grok 4 is “smarter than most grad students in all disciplines, simultaneously.”

Some thoughts on Grok 4 - Marie Haynes
July 10, 2025 - Grok outperformed all of the other language models including OpenAI’s o3 and Google’s Gemini 2.5 by a significant margin. Grok 4 Heavy, a model that uses multiple agents to brainstorm together on problems and also can use tools like code executions or search, performed exceptionally well.

July 10, 2025 - Grok 4 is xAI’s latest single-agent model (unlike Grok 4 Heavy, which uses multiple agents—we’ll get to that in the next section). Based on the livestream, there’s nothing particularly groundbreaking in terms of engineering.
