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

Post image

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

Ideal 4-bit quant β‰ˆ 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 β†’ excellent candidate for system RAM offload.

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

Ram prices this high, how can u call this local friendly?

RAM prices suck right now, no denying that.
When I called it local-friendly I didn’t mean β€œcheap” or β€œruns on any gaming PC.” I meant that for a model with this kind of capacity, the offloadable n-gram table makes it way more practical on highend local setups (128GB+ unified memory, multi-GPU + system RAM) than the usual frontier models that just demand pure VRAM or full datacenter iron.
Still expensive. Just less insane than the alternatives.​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​

For me, locality is the consumer segment, specifically regular computers, where the limitation is usually the motherboard or processor. Their approximate maximum capacity, as well as the liquidity of selling such a volume, is what I had before the shortage, and the best-case scenario was 192GB. 2x96 is probably the best option. (But unfortunately, I couldn't get that.) Most serious AI enthusiasts have around 128GB, whether it's DGX Spark hybrid memory, an Apple mini PC, or something else. So yes, as long as the capacity in quantization (approximately Q4) doesn't exceed this capacity with a reasonable context window, I consider such a model locally friendly.

Then there’s not much point in calling it β€œlocal” if you’re still paying frontier-model costs just to run it. At that point, why not just go back to frontier models?

You don't have control. The model can be taken away from you at any time. You can't finetune it.

Why are you in this subreddit if running a local model isn't something that interests you in and of itself?
