Qwen3.6-35B-A3B-PRISM-NVFP4
NVFP4 (W4A4) quantization of a PRISM-tuned Qwen3.6-35B-A3B. ~24 GB on disk, multimodal + MTP draft head preserved. Designed for NVIDIA Blackwell (SM120/SM121).
PRISM softens over-refusal behaviour and removes bias / propaganda patterns while maintaining and enhancing task performance, coherence, and multimodal capability.
Model details
- Base: Qwen/Qwen3.6-35B-A3B (35B total, ~3B active per token, 256 routed experts)
- PRISM: refusal-softening, bias + propaganda removal
- Format: compressed-tensors NVFP4 (FP4 E2M1 weights + activations, UE4M3 per-block-16 scales)
- Kept BF16: vision encoder,
lm_head, router gates, embeddings, linear-attention SSM state - Runtime targets: vLLM (
--quantization compressed-tensors), Blackwell tensor cores

Requires vLLM with Blackwell NVFP4 kernels. On SM121 (DGX Spark), use a
vLLM build with SM121-aware patches — stock PyPI wheels will fault on the
missing cvt.rn.satfinite.e2m1x2.f32 PTX instruction.
Known-working community Docker images (Apache 2.0, tested on GB10):
ghcr.io/aeon-7/vllm-spark-omni-q36— vLLM HEAD + GB10 patches + flashinfer sm_120 kernels; also supports DFlash speculative decoding.avarok/dgx-vllm-nvfp4-kernel— generic NVFP4 MoE image with software-E2M1 conversion and Marlin-MoE default.
