This project is a gigantic waste of resources, it’s fine tuned on politics of the CEO, was used for CSAM generation and just sucks overall

Pelican riding a bike here: https://gist.github.com/SerJaimeLannister/f6de26bd0d0817e056... (ran this on arena.ai direct chat and also tried to write this gist inspired by how simon writes his gists about pelicans) Edit: just realized that I made pelican riding a bike instead of bicycle, which now makes sense as to why it hardened the bicycle to look tankier, going to compare this with pelican riding a bicycle if any…

https://simonwillison.net/2025/Nov/13/training-for-pelicans-... You should probably come up with variations, like a beaver riding a scooter or something, just to see what's what :)

Thanks I have generated both

beaver riding a scooter: https://gist.github.com/SerJaimeLannister/f6de26bd0d0817e056...

pelican riding a bicycle: https://gist.github.com/SerJaimeLannister/f6de26bd0d0817e056...

Personal opinion but the beaver one looks especially bad as compared to pelicans. Can we be for sure that this model of grok-4.3 hasn't been trained on pelican. Simonw in blog-post says that he will try with other creatures so I hope he does that but it does feel to me as the model/xAI is trying to cheat, Hope Simonw tests it out more.

Edit: Also added turtle riding a scooter, something which literally has images online or heck even teenage mutant ninja turtles and I thought that it would be able to pass this but it wasn't even able to generate this: https://gist.github.com/SerJaimeLannister/f6de26bd0d0817e056...

This literally looks more avocado than turtle. Perhaps this could be a bug from arena.ai or something else too, not sure but at this point waiting for simon's analysis.

As an English-as-second-language speaker and writer, one thing Grok really shines at is capturing the tone and level of "formality" of a piece of text and the replicating it correctly. It seems to understand the little human subtleties of language in a way the other major providers don't. Chatgpt goes overly stiff and formal sounding, or ends up in a weird "aye guvnor" type informal language (Claude is sometimes better but not always).

Grok seems in general better at being "human" in ways that are hard to define: for eg. if I ask it "does this message roughly convey things correctly, to the level it can given this length", it will likely answer like a human would (either a yes or a change suggestion that sticks to the tone and length), while Chatgpt would write a dissertation on the message that still doesn't clear anything up.

Recently I've noticed that Grok seems to have gotten really good at dictation too (that feature where you click the mic to ask it something). Chatgpt has like 90-95% accuracy with my accent, the speech input on Android's Gboard something like 75%, Grok surprisingly gets something like 98% of my words correct.

Grok is my favorite model for chatting, and my favorite voice mode. It seems to be the only voice mode that isn't routing to a extremely cheap model (like Haiku), and has been the highest quality out of all the frontier ones. When you subscribe to SuperGrok you can also create a "council" of agents, each with their own system prompt and when you ask something, they will all get asked in parallel to come to a conclusi…

When I signed up, I accidently paid for a full year. So from time to time, I'll throw it something just to see what it produces compared to the other LLMs. And, even after all this time, it still feels like a really "dumb" model compared to the other frontier ones. But, worse, many of my system prompts make it go wacky and puke jibberish. However it was pretty cool for those couple months awhile back when it was uncensored. You could ask it about a wild conspiracy, and it would actually build the case and link you to legitimite source material. They dropped the hammer down on that real quick.

I also think Grok would benefit from allowing usage of "SuperGrok Heavy" (their $300 plan) in coding harnesses with included usage. Currently they give you some API credits on the Heavy plan so you can use some Grok for coding, but $300 USD value is just not there.

Not saying they should create their own grok-code harness, just allowing usage in existing ones would already be beneficial. But that's probably what the Cursor acquisition is going to do eventually

So, we have: - claude for corps and gov - codex for devs - grok for what, roleplay, racism? Those are the two things I've ever heard grok associated with around me.
