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

They're not filling datacenters with 3090s. With the amount of headache and the amount of infrastructure needed to support those beasts, do they even have a resale price at all? Or just scrap value?

Yes. Their resale price is in the same range as the cost of a new car. I'd buy one if I could, but they're too expensive for me.

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.

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.

pi is the neovim of agentic harnesses, its barebones and extremely configurable. if you're the sort of person who likes that sort of things its a forever product, nothing is going to displace it because you have full control. opencode builds a lot more in, which is better if you dont want to fiddle with config.

nice. i had thought the consensus had moved pretty firmly towards pi, so i was surprised to see Thinking Machines demoing their new model Inkling in OpenCode. wondering if they are previewing an acquisition

OpenCode is a good baseline for "open-source harness with most the stuff already configured an average person will need".

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…

Interesting. Thai characters can also blow it out, I imagine because of the difficulty mapping glyphs to width:

To my surprise, Sublime Text gets it almost right:

I tried finding a Thai monospace font and using that in the HTML but it was worse, probably didn't have the box drawing chars.

Still a fun tool and useful for lots of ASCII cases!

Relative to OpenAI, Anthropic, and Google in the AI space? Absolutely.

David was a good vs evil with an order of magnitude fewer resources on the good side. XAi is evil vs evil with comparable resources on each side. Now this is where I know you’re MAGA because as I’ve said a million times you guys don’t do fair comparisons.

xAI, by all accounts, is not a real playing the frontier AI model market. By a long shot by many accounts.

It’s a shame that their leader exfiltrated government data.
