The checkpoint keeps the source fused 3-D gate_up_proj and down_proj expert tensors rather than per-expert 2-D weights. Two complete linear/linear/linear/full cycles are retained. The Qwen3.5 MoE linear-attention path requires CUDA and Triton. The exact public snippet was verified on an NVIDIA A800-SXM4-80GB.

Example usage

Transformers (✅ verified)

The example sends one image and one predecoded video. The Qwen3.5 MoE linear-attention path requires CUDA and Triton. Install transformers[torch]>=5.18.0 and Pillow.
