> Qwen3.8-Flash-Next features a 125B-parameter main model, supplemented by an additional 51B N-gram embeddings, with 6B parameters activated per token.
Didn’t see this mentioned yet. I wonder what this means for the effective size. It’s evidently ~176B paramètres, but how does that get quantized. A 4-bit quant under 100GB seems unlikely, I’m suspecting this won’t run in 128GB unified memory
In principle I like the idea of trading more memory for compute though, even if there’s a memory shortage right now
It is 125B A6B. vLLM is already out with support, ngrams can be offloaded to RAM so you only need ~96GB VRAM for nvfp4 w/ full context.
Likely soon we'll see nvme offloading for ngrams as well. They're just an index, so that should be plenty fast for what it does. LLama.cpp support should come soon as well, and they might do some things with offloading first.
Still working at it. Prefill sucks still but decode is about 12 tok/sec and the model weights fit nicely in the 128GB Spark memory in nvfp4 quant while paging the ngram stuff from disk.
(EDIT: merged to main. 80tok/sec prefill, 12 tok/sec decode, ~80GiB resident, the rest paged)
People in my server are running it on Strix Halo 128GB using RoCmFP4 and reporting 35tok/s, without much optimization, with proper MTP, better kernel, expecting about 50-60tok/s.
> You will need at least 75 GB of RAM or unified memory to run the model. Its smallest 1-bit quantized version is larger than usual because of the model’s architecture so 1-bit isn't really 1-bit at all. However, this also means the quantization is less aggressive, allowing the model to retain more of its original accuracy than more heavily quantized models.
Lots of RAM required even for the 1-bit, which is already downloadable. Interested to see how well this one works compared to Ornith1.5-35B-A3B I've been running (and quite happy about).
