I had Fable 5 compile that Rust code to WebAssembly and build a browser-based playground for it, so you can try it out with Mermaid diagrams here: https://tools.simonwillison.net/grok-mermaid A few more notes on my Grok code explorations on my blog: https://simonwillison.net/2026/Jul/15/grok-build/

I love this kind of stuff (ASCII art, if you will), but it just breaks down too easily as soon as Unicode characters (mainly CJK, as I'm Chinese) and fonts are involved. For example, on your website, any chart or plot involving horizontal arrows breaks down because the assigned font-family (`ui-monospace, SFMono-Regular, Menlo, Consolas, monospace`, which ends up as Consolas on my machine) has no such glyph. Thus, it…

I was going to say, perhaps generate a failing test case, but testing for proper unicode rendering might be tricky??

These are all pointless forks, they will die in a year. Bookmark this and check back.

While I'm sure most of them will die, there will certainly be 1 or 2 that the community rallies behind

Why when they can just fork it and improve it on their own with AI?

Not a fan of Musk either, but him being "Racist" or throwing a Nazi Salute are quite frankly the least of my concerns with him.

agreed, the de facto genocide bit is slightly more concerning to me

I didn’t say block all illegitimate uses, though. We’re talking very specifically about disabling the production of CSAM. Which is something Grok seems to be able to do now! So I’m curious what legitimate uses had to be sacrificed in order to do so.

> I didn’t say block all illegitimate uses, though. We’re talking very specifically about disabling the production of CSAM But what is “CSAM”? If by it you mean illegal material-different jurisdictions worldwide have different laws on that topic, so material which is illegal in one jurisdiction can be legal in another.

Ok, then let’s just say CSAM by definition of US law.

Twice now you’ve tried to expand the parameters of this so that it becomes something impossible to tackle. But there’s no actual reason to do that.

Grok is able to tackle CSAM, as demonstrated by the fact that they are currently doing it. The question is why they ignored the very public issue for as long as they did.

Don’t blame the people, blame Elon for turning his technical empire into a political one. He’s ruined his companies reputations.

Grok Build with Grok 4.5 is the best coding AI agent I have ever had the pleasure of using. Stopped using Fable after it.

Data centers without local protests?

I mean real things, not ridiculous bullshit to con investors and rubes

Amazon and Google are also pursuing the same thing. Either all three of these companies are full of it or they believe they have solved the blocking problems.

You will be surprised how much code goes into creating harnesses.

Alright I’ll bite. Why do harnesses require so much code?

>The key difference between xAI and Anthropic/OAI/Google is that xAI has the least-likely path to existing as viable business in a decade. I don't know, renting out a fleet of GPUs at annualized rate of ~100% of the capex deployed to obtain said GPUs seems reasonably better than lighting hundreds of billions of dollars on fire in order to earn tens of billions of dollars.

The GPUs that depreciate like gangbusters. Yeah, solid long term plan.

3090s are still selling at damn near their release MSRP.
