Grok 4 Heavy (left) V.s. Gemini 2.5 Pro (right)

Create a Turing-complete Scheme interpreter in C that supports lexical scoping, closures, continuations, and proper tail-call for tail recursion without stack growth.

Grok4 won. It wrote superior code.

Grok4 Heavy: 903 Lines of C code.
Gemini 2.5 Pro: 891 Lines of C code.

Both compiled!

The code from Grok 4 Heavy worked flawlessly.
The code from Gemini 2.5 Pro did not work even after multiple prompts.

Grok 4 Heavy: ~10 minutes single prompt.
Gemini 2.5 Pro: ~2-3 minutes per prompt after about 10 prompts I gave up.

Bottom line though:
Grok 4 Heavy was smarter 2 weeks ago than GPT5 is now and G4H is already a lot better.
Let that sink in.

Funny side note: I have scheduled tasks sent to my inbox from Grok4. One arrived while recording this video. Doomers are citing ethics about memes. 😂

My thoughts on Grok 4 Heavy after 12hrs:
Crazy good!
“Create an animation of a crowd of people walking to form “Hello world, I am Grok” as camera changes to birds-eye.”
And it 1-shotted the entire thing.
No other model comes close.

Honestly xAI could just serve Grok 4 Heavy forever at this point and they will have impacted science and truth seeking more than any human.
The current capabilities for math and physics are pretty astounding.
We might just pass the great filter.
