There's some surprising stuff in this codebase. For example, https://github.com/xai-org/grok-build/blob/b189869b7755d2b48... is a "self-contained terminal renderer for Mermaid diagrams", which renders a subset of Mermaid chart types using Unicode box-drawing.

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/

Thank you for creating an alternative to the toxic mermaid renderer on their website.

Trying to monetize Mermaid was disgusting and honestly rings to me like trying to monetize Markdown.

What does this open source that the Codex harness hasn't already?

You can't use your mouse with command line Codex.

I really hate that they added mouse integration with Claude Code.

Nothing like it prompting you for an answer and you click on to the terminal accidentally, resulting in you choosing an answer.

It's a shame that they exfiled private data. The model is actually good (better than opus 4.8 imo) and the harness itself is butter smooth with the potential of being the best out there.

This has been my experience as well. In fact, Grok 4.5 is better at visual design than Fable from what I've seen. And being (based on vibes) 2-3x faster? It's an easy sell to me.

I agree. I subscribe to SuperGrok but never used the grok models a lot for coding. Now with 4.5, I’m gonna hit my weekly limit tomorrow and even considering trying SuperGrok Heavy

I really like the feel of Grok 4.5

I had a very weird experience two days ago where Cursor-Grok-4.5 was either stuck in a loop (it would keep attempting to answer the prompt over and over), or else it would just quit halfway through a reasoning loop. Might have been that I was using omp, but it's still not the most stable thing out there. Nonetheless when it's working, it's pretty good, and for the price ($10 a month) is an absolute bargain.

What’s this $10 deal?

Because I don't believe what you just said about him. Literally not even one detail.

Seriously? His destruction of USAID and the various estimates of resulting deaths is well documented. https://www.impactcounter.com/dashboard?view=table&sort=titl... https://www.thelancet.com/journals/lancet/article/PIIS0140-6...

Those numbers always crack me up. If you do the math that way (US funding cuts kill people), imagine how many people we’ve killed by not confiscating all the wealth of our nation and shipping it to Africa!

Ok done. Still don't believe it cuz the facts don't support it. It's interesting to see how far people attempt to stretch the facts tho.

He publicly and financially supported literal fascists in Germany. Nothing can be more blatant than that. QED.

I don’t think the AfD is “literally fascists.” They certainly don’t claim to be.

No he doesn't. There's a lot of bullshit surrounding him. Things are taken out of context. I will say this, he believes in things about race that are controversial. For example that races may have different IQs. But you have to realize we don't actually know if races have different IQs. The idea fits common sense though... if races can LOOK different... what black magic suddenly makes them completely equal in intelli…
