Hoping this is real. It's too bad to see the signals from Qwen that they will not be releasing a 35B-A3B for the 3.8 lineup. The MoE architecture makes a huge difference for being able to run these local models on reasonable consumer hardware.

Quick tests suggest it’s pretty good at reasoning and tool use (keen to search to check its thinking) and it seems to waste much less time thinking, too.

So it feels very fast.

But it does not seem to be better than Qwen 3.6 35B at coding. A bit worse, I think, though I will test it more.

If you have a machine that can fit a 35B model in VRAM, I would suggest testing Muse Glimmer with (from memory)

  Reasoning strength: low
in the system prompt.

Despite being a dense model, this is actually capable of solving code problems faster than the Qwen MoE, despite having only one fifth of the raw token performance.

Honest question/suggestion for the HN audience- Since Qwen released the weights for Qwen3.8 2.4T-A95B and we already have the staring point of Qwen3.6 35B-A3B, couldn't someone distill the bigger model and make a "pseudo" Qwen3.8 35B-A3B? Sure, it wouldn't be an official Qwen release but couldn't someone improve on Qwen 3.6 and get the thing everyone is asking for?

I am calling this a suggestion for the audience because I don't have the will/resources to do this.

Personally I find speculative decoding much better strategy than MoE – performance wise it's there at 90-100 t/s on 2x4090, great intelligence – really great fit.
Re:Ornith-1.5: From Self-Scaffolding to Self-Improvement by d4rkp4ttern on Wednesday August 19, 2026 @02:42PM (#49365522)
A lot of people, including me, don’t want to bother with GPUs, they’d rather run it on their M1-M5 MacBook. For example the 35B-A3B is very usable even on a M1 64GB MacBook.
Re:Ornith-1.5: From Self-Scaffolding to Self-Improvement by mirekrusin on Wednesday August 19, 2026 @03:30PM (#49366114)
Speculative decoding also works on Mac, 64G is more than what I have, m5 max should handle up to ~40 t/s with optimized setup (and with a lot of vram you can get great wins on concurrency – that harness can take advantage of for single user task as well), but agree memory bandwidth in mac or spark is still too slow, next gen for both will be great hardware to have for sure.
Re:Ornith-1.5: From Self-Scaffolding to Self-Improvement by smcleod on Wednesday August 19, 2026 @04:38PM (#49366908)
I get around 70tk/s on the m5 max, with 5bit AWQ / oQ5 slowing only to around 40tk/s at higher context.
Re:Ornith-1.5: From Self-Scaffolding to Self-Improvement by c0m47053 on Wednesday August 19, 2026 @03:41PM (#49366241)
MoE is great on systems that lack the VRAM to host the full model. On my 16GB VRAM system, I can get 100 tok/s with Q4 Qwen 3.6 35b a3b, and 15 tok/s with 27b.

MTP is a trade-off, as it pushes some more of the model off the GPU.

I have managed to get usable quants of Laguna S2 and even DeepSeek V4 flash on this setup.

There is clearly some intelligence loss compared to similar sized dense models, but I feel like it stomps on the 9-12b models I could run fully on GPU

I'm running qwen3.8 27B dense on reasonable hardware (oem spark)

tbh, I have stopped using MoE in the name of speed, the dense (with more active parameters) makes a real difference in output quality

Re:Ornith-1.5: From Self-Scaffolding to Self-Improvement by smcleod on Wednesday August 19, 2026 @04:35PM (#49366881)
The smarter 27B is so fast with MTP I've found I really don't need the 35B-A3B. You get around 70tk/s on a M5 Max lowering to around 40tk/s at higher context sizes.

I've benched 3.8 27B being significantly slower and less quality than 3.6 35B-A4B (both 4-bit quant, MTP, both using turboquant 4-bit served by oMLX), to the point that I'm not even using it right now (on an M3 Max). What's your use case and what did you observe? I might be missing something.
Re:Ornith-1.5: From Self-Scaffolding to Self-Improvement by smcleod on Wednesday August 19, 2026 @04:52PM (#49367097)
I believe you mean 35B-A3B, there was no such thing as A4B. I use 27B and other models for software development, and quite a few research or similar agents. I cannot imagine a world where the old 35B-A3B model is smarter / more capable than 3.8 27B - the difference is night and day for coding at least. Where 35B-A3B was fast and felt like a Haiku model, 27B feels like a strong Sonnet when given the right tools. I don't use turbo quant so can't comment on that, but with the A3B model you're using you probably won't get much from using MTP with small MoE models like that.
Re:Ornith-1.5: From Self-Scaffolding to Self-Improvement by seanmcdirmid on Wednesday August 19, 2026 @06:35PM (#49368059)
Yes, A3B, sorry for the typo. I’ve benched it and used it in practice for agentic coding, and I haven’t seen any benefit to it yet. Lightning MTP helps a lot in the perf department.

People over-quantize things, muck with the temperature and other settings based on superstitions or results from models they think are similar. There's lots of ways to make 3.8 27B dumber.
Re:Ornith-1.5: From Self-Scaffolding to Self-Improvement by razster on Thursday August 20, 2026 @01:37AM (#49370746)
I've had great success with allowing the model to review optimal settings and my system specs. It comes up with the right configuration. Running Pi harness. I just had Ornith 1.5 take a moment to configure itself, now it's reviewing a large project I'm working on, so far its really impressive for my needs. Qwen3.8 27b Unsloth(Dynamic 3.0) is also perfect. These two are working together, and I'm in a sweet-spot, I now have all I need.

I get ~10 tok/sec on a M1 Ultra, but the real issue is abysmal prompt processing which makes it unusable. On the M1 and M2 series MTP is actively harmful for performance.

Does 27b mean it fits one 32GB GPU?
Re:Ornith-1.5: From Self-Scaffolding to Self-Improvement by smcleod on Wednesday August 19, 2026 @04:53PM (#49367104)
It doesn't mean that, but yes it would (with a 5 bit quant).
Re:Ornith-1.5: From Self-Scaffolding to Self-Improvement by kzrdude on Thursday August 20, 2026 @03:28AM (#49371515)
27B means it has 27 billion parameters, but how that translates to model size depends on the model architecture. For Qwen 3.5 architecture (same as 3.8) the native size is around 55 GB memory. So you need quantization to fit it in 32 GB.

Go here: https://huggingface.co/unsloth/Qwen3.8-27B-GGUF

See the right hand side panel, you see a whole palette of quantizations and their respective sizes. Should give you an idea. Note that these are not the only quantizations available.

Re:Ornith-1.5: From Self-Scaffolding to Self-Improvement by jwr on Thursday August 20, 2026 @04:15AM (#49371825)
I would suggest careful benchmarking. I actually tested and benchmarked, and the new Qwen3.8-27B model is actually slower with MTP on my M4 Max. MTP only gains anything when generating long code sequences, which is very unlikely as the model spends most of its time thinking, not generating code, even if you use it for coding (which I don't).

I get 20 tokens/s on an M4 Max (larger GPU).

That shouldn't be the case, it sounds like you've got something else going on with your setup. Here's my benchmarks: https://omlx.ai/my/fadc2127d384283f5df1fcc2c093a9f95700c6a52... which are inline with the communities: https://omlx.ai/benchmarks/performance?sort=tg_tps&order=des...

Re:Ornith-1.5: From Self-Scaffolding to Self-Improvement by huseyinkeles on Wednesday August 19, 2026 @06:39PM (#49368082)
I've been experimenting with it on a M4 Pro 24G for the last few hours and it's been very promising using 32k context. getting around 30-40 tps

With Qwen3.8 27B I could not get anywhere near 32k context window, that made it very unusable for agentic coding, although it was very smart.

> The MoE architecture makes a huge difference for being able to run these local models on reasonable consumer hardware

That's not true. For computers without unified memory architecture (which is the vast majority) VRAM capacity is the bottleneck for local models. In that case a dense model can deliver significantly more intelligence than an MoE model of the same size. And for a typical consumer/gamer Nvidia GPU, dense models are fast enough.

Re:Ornith-1.5: From Self-Scaffolding to Self-Improvement by dannyw on Thursday August 20, 2026 @03:52AM (#49371658)
Expert offloading significantly helps with the VRAM capacity.

Most MoE architectures have a few experts that are always running; this, the router, KV, and whatever else you have space for can stay in fast VRAM; and the remaining experts can be offloaded.
