#172It looks like this also undercuts the already absurdly inexpensive Deepseek Flash in pricing. Wild.
Where are you seeing that? At the bottom of this post from Qwen I see: Qwen 3.8 flash: $0.16 / $0.47 Compared to Deepseek 0723: $0.03 / $0.075 (units in USD/m tok)

It looks like the 3-bit requires 90 GB[1] which, I imagine, would fit within the DGX Spark's 128GB of unified memory.

#176Adding to my homelab stack, hopefully it doesn't overthink like the little model. Actually, hoping it thinks a bit less. Wait actually I'm really praying it reasons a bit more directly. But wait, I'm really sure that it must be a bit better.
You’re absolutely right to be hopeful. Three honest possibilities, and I’ll be straight with you about each: 1. It overthinks — Just like the previous iteration. High confidence. 2. It doesn’t overthink — Improvement from the last model for your use case. Regression for others. 3. It sometimes overthinks — Best case all around. A feature, not an impairment. One final thing worth mentioning: (I made myself irrationall…

#177Interestingly they also share the parameter count for Qwen 3.7 Plus (397 b a17b). I don't think these were known before but I might be wrong.

#180It's in Unsloth Desktop already. Looks like it's 73GB, so 128GB Mac or Strix Halo etc will work. Exciting!
I only see a 1-bit quant posted on unsloth HF and it’s 72.5 GB. Is that what you mean? That’s much bigger than I expected. If you can’t run a 4 bit quant in on Strix Halo it becomes a lot less interesting. https://huggingface.co/unsloth/Qwen3.8-Flash-Next-GGUF
If that's true, it'd scale linearly with number of bits in the quant with an offset of about 51gigs. So Q4 should be a bit bigger than 82gigs, I'd guess in the 90s (as opposed to a ~280gig q4 if the whole 70gigs of the 1-bit quant scaled linearly).
