Description
This Qwen3.8-Flash-Next-NVFP checkpoint contains the main model weights from nvidia/Qwen3.8-Flash-Next-NVFP4 and combined with MTP head from the official BF16 Qwen/Qwen3.8-Flash-Next. PLE table is unmodified FP8 from Qwen.
The model is resharded to reduce RAM pressure when loading the model.
This model will run on a system with 1x RTX Pro 6000 and 96gigs of system RAM. The main weights and MTP head will be on the GPU and the PLE n-gram table will be offloaded to system RAM.
No patches are needed to run this checkpoint as all the required fixes has been merged into VLLM.
Instructions
Updated Oct 29, 2026
First, pull the vllm docker nightly image:
docker pull vllm/vllm-openai:cu134-nightly-3966924d566340e971a6da313e790d05492aa505
Download the model:
hf download dicksondickson/Qwen3.8-Flash-Next-NVFP4-reshard-mtp-fix \
--local-dir ~/models/dicksondickson/Qwen3.8-Flash-Next-NVFP4-reshard-mtp-fix
To load the whole model you will need to increase your swap to at least 64gigs.
# create temp swap
sudo fallocate -l 64G /tmpswap
sudo chmod 600 /tmpswap
sudo mkswap /tmpswap
sudo swapon /tmpswap
swapon --show
Then drop caches and adjust swappiness to prevent the PLE table from being evicted from system RAM:
ssudo sh -c 'echo 1 > /proc/sys/vm/drop_caches'
sudo sysctl -w vm.swappiness=1
sudo sysctl -w vm.vfs_cache_pressure=200
sync && sudo sysctl -w vm.drop_caches=3
Now run vllm using:

MODELPATH="/root/models"
VLLM="vllm/vllm-openai:cu134-nightly-3966924d566340e971a6da313e790d05492aa505"
