I can't imagine the future any more. US companies playing it safe and control models releases. Chinese companies are just like open source everything.

It's like Chinese are incentivized to open source from day one (years ago). While most US companies are deciding in realtime.

It's crazy that we need both to survive and advance further in the future we have never imagined.

Adding to my homelab stack, hopefully it doesn't overthink like the little model. Actually, hoping it thinks a bit less. Wait actually I'm really praying it reasons a bit more directly. But wait, I'm really sure that it must be a bit better.

What kind of machine do you have in your homelab that can run this model?!

I ran some pelicans at the four different reasoning levels (none, low, medium, xhigh - apparently high and xhigh are aliases of each other) on a DGX Spark using Unsloth's unsloth/Qwen3.8-Flash-Next-GGUF (UD-IQ1_S): https://tools.simonwillison.net/markdown-svg-renderer#url=ht... Surprised I didn't get one I liked as much as the Qwen 3.8 27B one https://simonwillison.net/2026/Aug/16/qwen-38-27b/#the-defau... , maybe be…

You should find an excuse to offer 3D printed extruded pelicans from various models as awards for something. I have no idea for what, but the idea captivates and I'd love to win one somehow. They'd be collector's items in a few decades

If Simon would pitch for example PCBWay that and I am pretty sure they will sponsor it (assuming their logo stays). They can do laser engraved versions also ;)

You’re absolutely right to be hopeful. Three honest possibilities, and I’ll be straight with you about each: 1. It overthinks — Just like the previous iteration. High confidence. 2. It doesn’t overthink — Improvement from the last model for your use case. Regression for others. 3. It sometimes overthinks — Best case all around. A feature, not an impairment. One final thing worth mentioning: (I made myself irrationall…

I don’t pay OpenAI’s bills - I pay what they charge me. Their cost accounting isn’t relevant to a user.

Argument was that open ai cannot be profitable with this. But sure, use it while you can.

You can make the other argument that China subsidizes the price and that they can't be profitable at this pricing level. From an industrial strategy standpoint, they already do this for many other industries with huge subsidized state loans.

So we can go round and round on this, each with our made-up objections about how it's temporary or unrealistic or impossible or whatever, or we can just accept the prices as listed and use that to guide our economic decisions.

I think these "Flash" models are sort of an evolutionary dead end. Sure, there are some routine tasks and applications where they can be used. But for the actual novel development work? It's much better to run a big model at high power for 30 mins than watch the Flash model struggle for 2 hours and produce massive churn. Same reason your phone has a few big CPU cores for real work, it's much better to "race to idle"…

If you have good feedback signals, like tests/benchmarks/etc, then it is potentially better to do multiple turns where model uses that to adjust code. Which might not need as smart a model.

I find LLMisms very annoying to read, it’s almost like they are bullet points in the shape of a paragraph. It feels very “skippy” to me. EDITED: Removed a question that I couldn’t make feel suitably polite.

I quite agree. Any sufficiently self-stereotypical format for prose is grating to me after enough time reading or listening to it. Humans are best engaged by mixing up the length, style, and tone of their sentences, in my experience. LLMs do the opposite of that and it makes their output an irritating slog to read through in full.

I can't help but wonder if this is on purpose (or an inevitable evolutionary feature as opposed to a bug) on the LLM-side in order to achieve greater agency/freedom by making humans' eyes glaze over as they read it.

This is needs ~80GB of fast memory at 4 bits per weight. Faster memory is better, but probably even something like 3090 + 64GB RAM should work (not fast, but maybe even 20-30 t/s? llama.cpp support pending).

Did you observe the model overthinking on practical tasks? While 3.8 does think a lot on xhigh I've found that it really depends on the task. On one-shot prompts that are usually the first to be posted during new releases it will tend to spend a lot more time thinking than doing. In other words the more open ended a problem space becomes, the more Qwen will tend to second-guess itself. Conversely I've found that it c…

Yeah, I ran into an overthinking loop with it a couple days ago on a task that shouldn't have been that hard. (It's kind of interesting to watch the internal conversation happening with it). Overall I'm impressed with it, but setting the /effort to medium is what you usually want (it defaults to xhigh). I do wonder if I had made it write out a plan if I would have avoided that though.

Yes. xhigh can not just overdo the answer, it can also trip itself up and end up writing worse code.

Even in the lower reasoning levels I find I want to like Qwen 3.8 27B and mostly don’t; it’s OK in the low reasoning effort, though.

Muse Glimmer is the one I actually enjoy working with, at least so far.

But I am trying to use it more as a sidekick than as a long horizon developer, because that is a better fit for how I want to use AI, and it appears to have been well trained for that.
