Does the current model have dspark support?

DeepSeek-V4-Flash-0731-GGUF contains a "dspark" model, but the current model does not exist. May I ask if it is supported?

It works for me - just use the original dspark gguf that was provided with the non-vision unsloth model.

I was able to

app-b10796-mix-659e406-windows-x64-cuda13-portable\llama-server.exe (switches not specific to the execution)
-hf unsloth/DeepSeek-V4-Flash-Vision-Exp-GGUF:UD-Q8_K_XL  --ctx-size 262144  --temp 1.0 --top-p 0.95 --reasoning on  --cache-type-k q8_0 --cache-type-v q8_0 --fit on  --spec-type draft-dspark --spec-draft-n-max 4 -hfd unsloth/DeepSeek-V4-Flash-0731-GGUF:Q8_0 -lv 4 --seed 7417 -np 1 

and it pulled the dspark from the other repo like I was hoping...
but this ran at 15 token/s whereas without dspark i get ~30 token/s
so idk what is going on there

Unstudio log says: "DSpark requested but no matching dspark-*.gguf sidecar was found; loading without speculative decoding."

But there is no sidecard, might try the sidecar from the non-vision model, but that's shaky at best. Looks like dspark is baked/fused into the .gguf, but doesn't work with unsloth studio/llama.cpp at all, and is only for vLLM and Sglang running on nvidia.

Per my Qwen:

The Vision-Exp model does have DSpark — but it's fused into the checkpoint, not a separate sidecar file. Unlike the 0731 base (where unsloth ships a standalone dspark-DeepSeek-V4-Flash-0731-BF16.gguf
Why you can't just switch it on: the runtimes that read that fused module are:
    vLLM: --speculative-config '{"method":"dspark","model":"deepseek-ai/DeepSeek-V4-Flash-Vision-Exp","num_speculative_tokens":3,...}'
    SGLang: --speculative-algorithm DSPARK (no draft path)
…both of which, for the vision model specifically, are pre-release and NVIDIA-only. 

I'm guessing someone is working on this, but it might be nice to note in the model card. Especially since it's only noted in the log, not in the UI other than slower performance compared to the original non-vision gguf.

oh what a bummer, lack of this kills it for me.
