@astuyve I love that mailing list! I dip into it occasionally just to remind myself how complicated and fascinating the real world is

@johannesweiss I got the impression that their custom harness is most of where their development effort has gone

@vishal8shah @emollick There is no other human involved, that's the problem
(There's a chance another human might read my reply, but if they didn't ask the original question the chance the answer is useful or relevant to them is much lower - and not worth my time investment)

X should have a zero tolerance policy for AI replies
Like you do one and your account is suspended for life
Replies are a nightmare now and it's never ever been this bad
AI replies are an an existential threat to the future of this platform, because people will simply stop using it if the vast majority of replies are AI bots

@vishal8shah @emollick A "good" comment with AI is still a bad comment, because any time I spend thinking about and replying to it is wasted when there isn't another human at the other end of that effort

@progrium I've been using "AI mania" for when you get carried away building things that you don't even need (and feel stressed when your agents aren't working on anything), but your thing here sounds like something different to that

Inspired me to try out spawn.co on my phone. Here's me flying a dragon around a castle, I prompted both the castle and the dragon into existence using the in-game "Savi" chatbot

the secret to becoming an expert is embarrassingly boring: build in public, write down what you learned and the process behind it, teach all that to someone, help them ship
repeat for a few years, and you're solid
repeat for a few years, and you're solid

I think October represents another inflection point in capabilities for coding agents and the models that drive them: Claude Opus 5.5 can now build video games that are actually fun simonwillison.net/2026/Oct/28/vi…

These ones are pretty great!
Apple II Agent (Opus 5.5) drew a pretty good pelican riding a bicycle (cc: @simonw) on the Apple Ii
Seen here in both color and monochrome

@brandur You made me realize that I used to LIVE in the Python REPL and Jupyter notebooks and I've hardly used either in the past six months

More notes on Kimi K3.1 - this one is I big deal, first time an open weights (well, soon-to-be open weights) model has competed this credibly with the current frontier simonwillison.net/2026/Oct/23/ki…

Introducing Kimi K3.1 Pro: our most capable 3T-class open-weight model.
🔹 1M-token context, 2.8T total / 104B active params (MoE), Multimodal.
🔹 Full-project coding: games in Unreal, Unity & Godot.
🔹 Excels at parametric 3D modeling in Blender & CAD.
🔹 More reliable at finance with hallucination down by 65%.
🔹 Matching the strongest proprietary models across coding, agentic and knowledge benchmarks.
Kimi K3.1 Pro and K3.1 Pro Highspeed (2–3× faster) are now live on Kimi.ai, Kimi Work, Kimi Code, and the Kimi API.
Open weights by Nov 4, 2026.
