I use it with a strix halo server. 35B runs stupidly fast. 27B is about 700 TPS prefill and 30 TPS token generation. Which interestedly is about what Kimi K3 gives me depending on provider.

what hardware do you use or recommend for this? never heard of it until today.

RTX 4060 and above. Ideally RTX 50 Series, because you can run NVFP4-quantized GGUFs that give you better prefill AND better quality.

They've also announced Qwen3.8-27B being released open-weight next week. Qwen3.6-27B is widely regarded as one of the best local models, especially since nothing else comes close to it, that isn't benchmaxxed, without being significantly larger. If 3.8 truly improves upon it that would be awesome.

Some advice I got from another HN Mac user was to run local models in energy saver mode. You'll get slightly reduced tokens, but the laptop won't overheat and the fans won't go wild.

And if you're running it on a dGPU, power limit it, because you lose very little in terms of token generation performance, since it's memory-bound.

This is what I've been waiting for. We are still using fine-tuned deployments of Qwen3.6-27B with a lot of success but could use a bump in intelligence. Here's hoping.

How and where do you finetune it?

Easy to do with Unsloth Studio.

> $200 in rent every month into the large model providers We all know that is hugely subsidized, and I guarantee that OpenAI and Anthropic are looking to enshittify that ASAP. The enterprise users, however, are not subsidized like that. They pay per token. And some developers in those companies are chewing down a lot of tokens. Self-hosting an open weight model could be a massive savings very quickly. It also gives t…

We all ASSUME that. For all we know, inference might be dirt cheap, they might just be hiking the API prices so high for us to think subscriptions are subsidized.

Well, it is always possible that OpenAI and Anthropic have some secret sauce that they are hiding that nobody knows about. However, the pricing of tokens on places like HuggingFace and OpenRouter suggests that probably isn't true. In addition, the lack of reliability and general slowness of Opus and Fable at various times also suggests that.

Now, the one wildcard in all of this could be Google. They are on the eighth generation of their TPU and have been holding their cards extremely close to the vest. I don't think anybody has a good read on exactly how much capacity they have. Most things you can kind of figure out the overall business numbers and what's going on in Google--the TPU area is one of the exceptions. I know a couple of big customers and even they don't have any visibility on that front.

Really awesome. Though I wish they'd do a dense 48B, 60B or 72B.

There seems to be quite a gap between the small ones and the enormous ones these days.

Qwen3.6-35B is my daily driver for AI, and what convinced me to cancel my Claude subscription back in April. The Qwen3.6 line is easily the best local model I've tried, and I've tried a lot. I've got it diligently grinding away on my laptop right now, reviewing and fixing some bugs in my F# code.

On what hardware do you run the model locally, if so?

Not the GP, but I run this model as daily driver too. It runs great on a Macbook Pro 64GB (M3 Max). Token generation speed can be about 100 tokens/sec with multi-token prediction, although it depends on the context. Worst case speed is around 50 tokens/sec.

The weaker point is prompt prefill, which starts at 1,400 tokens/sec but decreases significantly at high contexts. That said, for agentic scenarios, if you're using a harness that doesn't needlessly bust the cache, it doesn't feel slow.

I really hope they release a Qwen 3.8 35B, although the lack of a mention seems ominous.

Maybe you're anti-AI because you're really anti-outsourcing your thinking to some remote corporation you don't control? That's one of my main issues with AI anyways, the thought of having all my data go through some sketchy foreign (to me) entity with questionable motives and under a questionable regime. Local AI solves for all of those.

I'm not against AI. I'm calling out the hypocrisy in the comment. I'm anti-AI, but will spend hours trying to setup a local model, instead of just getting access to frontier intelligence in 15 mins, and actually getting useful work done.

If you're learning about model inference, then it's a different and you are definitely not anti-AI in that case.

that is not an model issue but a harness one, if you don't want it to have io to files or run command then simple don't give it access to the tools.

Yes, I don't. I have my own harness where the agent is only able to do a set of predefined things and none of them involves the internet. However, I imagine the model could be a lot smaller if it does not have the baggage of coding and programming in general. I mostly just need it to mostly be a very advanced NLP model that is able to figure the set of tools that it needs to call with what argument. Then it will just…

Check out cactus needle, might be what you're looking for.

The 27B have many more active parameters than much bigger models such as DS4Flash, MiniMax etc, which makes it punch above its tiny weight. A great fit for a 5090 in a closet for meat-and-potatoes, kind of work.

AI is a commodity. This is proven now. And valuations will have to drop 90%.

There's a lot of AI models that each 'win' one week over the next. The pure definition of a commodity market and not a 'winner takes all market' as valuations would imply
