Qwen3.8-Flash-Next much worse than DeepSeek-V4-Flash?

According to benchmarks Qwen3.8-Flash-Next (Q38FN) and DeepSeek-V4-Flash (DSv4F) are very similar.

However, when it comes to real world usage, there is a big difference:

- DSv4F: Can be run lossless at 162GB (Unsloth Q8_K_XL) at decent speeds. On my 4 x rtx 3090 with 192gb ddr4 @ 3200mhz I get ~30 tps and ~230 pp

- Q38FN: There is currently no Q8 available from Unsloth, but to run this lossless you'd need 360 GB. That's is more than double the size! Unsloth has no files up, but they lists Q8 - not lossless! - at 270GB (Reference)

I get that Q38FN is still very early in it's architectural lifecycle, so many speed and other improvements are still to come. But it sure looks like Alibaba achieved the benchmarks by making the model much, much bigger?

Will Unsloth be able to eventually offer a Q38FN lossless Q8_K_XL similar in size compared to DSv4F? My understanding is that because Qwen wasn't trained in Q8, this isn't possible.

tldr; Seems that benchmarks are currently very misleading because Q38FN is much, much bigger than DSv4F. I would imagine once you quantize Q38FN to a similar size (Q4 / Q5) it's performance would be much worse
