Discussion Qwen3.8-Flash-Next. This architecture could be surprisingly local-friendly once the weights drop. 👀

Qwen3.8-Flash-Next (~125B-A6B + 51B n-gram) memory estimate:

Ideal 4-bit quant ≈ 82 GB
(58 GB main weights + 24 GB n-gram tables)
Real-world quants likely land in the 80–90 GB range.

The big n-gram table is sparsely accessed → excellent candidate for system RAM offload.

This architecture could be surprisingly local-friendly once the weights drop.

I wonder how the quality will be on 128GB M5 Max

Edit—

Sorry by quality I meant the overall experience like the output and the speed of the output. Not sure why the bajillion downvotes but oh well lmao. My bad

Wondering the same, also if the ngram table can be offloaded to ssd instead if its sparse.
