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.
Even if 95% of the spam gets actively reported and dealt with, that still leaves a ton of nonsense on the platform, getting fed into the LLM. And spam has only gotten worse over the years, as the barrier to entry has lowered and lowered.
Especially you as a 'english-as-a-second-language', the hitler grok doesn't like people like you :|
Just wish they would finally put some work into their apps, it's the only thing keeping me from actually subscribing to SuperGrok:
- No MCP / connected apps support. It's been teased but here we are, still not available. I can't connect Grok to anything, so I can't use it for serious work
- Projects are still not available in the app so as soon as you move something into a project, it's gone from all the native apps
- No way to add artifacts (like generated markdown docs) directly to a project, we have to export to PDF/markdown and re-import. And there isn't even a way to export artifacts. This makes serious project work hard because we can't dynamically evolve projects with new information
- No memory, no ability to look up other chats, each chat is completely new
- No voice mode in projects at all
If someone from xAI is reading this, please consider adding some of these.
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
Anyone remember why Oracle was named Oracle?
Grok has tool use, no? Why would you also need MCP? What does MCP add?
Low relevancy in spite of cluster size and musical chair gas generators for time being:
https://techcrunch.com/2026/04/30/elon-musk-testifies-that-x...(Affiliated with no AI company, just surprised to read this yesterday - how could Elon miss model cards…concerning…, & the fact money can’t buy success every time.)
I don't like Musk or Grok. But not knowing what's a safety card is not a signal of anything IMO.
I think there's a surprising number of actually useful applications in this sort of grey area for a slightly-less guardrailed, near-frontier model (also the grok-fast models are cheap!).
People are mostly using GLM and Deepseek via API and Gemma4 and Mistral finetunes locally.
It seems to me like the roleplay market is comparatively old and mature and users have developed cost consciousness and like models to follow their workflow/preferences. So something like Opus is liked for its smartness but considered too expensive and opinionated.
Might be an interesting data point for how the other markets might develop in the future.

The first question was around setting up timers for a Fox ESS battery in Home Assistant and disconnecting Fox ESS from the cloud. The second was around cornering speed in Sunnypilot and Frogpilot.
Somewhat niche but if an AI is confidently telling you something wrong it's hard to work with.
But they all do that. It just comes with the territory. Grok will absolutely do the same thing another time you try it.
Like yeah tonally I guess there are. But with regard to references and information? You’re literally just using three different slot machines and claiming one is hot.
I suppose though I shouldn’t be that surprised then since Vegas and every other casino on Earth has been built on duping people in that exact way.
the smartest among them just make the tests complicated and biased; the less intelligent just cherry pick.
of course, would you really expect anyone to do real rsearch in this economy?
Grok if anything reduces populism because fake claims can be debunked
I hope the Cursor guys help them catch up to be closer to frontier models because they badly need help in it.
Nonetheless, the 10 Billion and 60 Billion deal with Cursor is weird as hell. I can only imagine that he wants to throw as much money at all of his shit before the IPO.
He probably wants the training data
Margins are going up for the 2 frontier model providers like crazy, and I don't expect it to go down more, I think we have seen the cheapest token prices already.
Pricing is also quite surprising, compared to comparable competitors. I guess they have tons of capacity or really want to bring over more people.
I hope Meta finally comes around, too. I want those sweet, sweet billionaire subsidized tokens.
I am old and cynical - I have no illusions, but I also have my limits and a semblance of moral compass. We, as citizens, can vote with ballots, but also with money.
And, no, I am not someone who keeps boycotting companies for every little grievance (was on the receiving end of that nonsense twice).
You're getting like 40k in tokens a year for $2400. A whole lotta people are about to be sad when they realize they bet their competency on that lasting forever.
I don't think there's a single thread on Xitter whete people don't delegate some question to grok.
(There's a separate conversation of failure modes, and whether it's a good thing, and how much control Elon had when he doesn't like Grok's "woke" responses)
Expensive miscalculation.
No way am I going to use a model where the backing has such blatantly obvious brain washing goals.
(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 anybody else shares the pelican riding a bicycle.
You should probably come up with variations, like a beaver riding a scooter or something, just to see what's what :)
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.
Thanks for generating those!
(Also it puts Opus 4.7 universally above Opus 4.6, and I may be wrong but this doesn't seem to match the experience of most/many/some people. I think it's widely recognized that Anthropic is severely lacking compute and Opus 4.7 is a costs saving measure)
But then, Anthropic employees don't have rate limits, right?
Update, I noted that Grok 4.3 is in the "Most attractive quadrant", that's cool! It is also in the top 5 highest in "AA-Omniscience Index", good! Really good.
It says #1 for speed but then in the chart it's #2. Also says #10 for intelligence but then it's #7 in the chart.
Politically motivated models can still do a lot of damage that affects me (or "have a lot of impact" depending on whether you like the politics or not) even if I don't engage with them myself.
Even with grock it's only broadening things to creepy corporate right of silicon valley.
I hate giving Elon any money. The man is a net negative to society but … if the models are objectively better then logically I must no?
