Thank you for this great model.

I was able to run it on an RTX 5090 with vLLM using:

vllm serve gittensor-model-hub/Qwen3.8-27B-NVFP4-RTX5090-LMHead4   \
        --quantization modelopt   \
        --kv-cache-dtype fp8  \
        --trust-remote-code  \
        --max-model-len 262144  \
        --max-num-seqs 16  \
        --gpu-memory-utilization 0.96  \
        --reasoning-parser qwen3   \
        --enable-auto-tool-choice   \
        --tool-call-parser qwen3_xml \
        --speculative-config '{"method":"qwen3_next_mtp","num_speculative_tokens":3}'

In actual testing with a single concurrent request, generation throughput was stable at around 120–130 tokens/s, peaking at about 130 tokens/s. When processing long prompts, prompt throughput reached up to about 7900 tokens/s. KV cache usage stayed at roughly 35%. Speculative decoding average acceptance rate was around 55–60%.
