Backbone and MTP formats are separate; inspect config.json, recipe.yaml when present, and pr3118-validation.json. NVFP4A16 is weight-only FP4 with 16-bit activations, not calibrated NVFP4 W4A4. MXFP4 uses dynamic activation quantization.
Source licensing remains applicable; consult the upstream model card. This validation adds no license grant.
End-to-end MTP test
Validated runtime baseline: vllm==0.29.1rc1.dev79+g767d1c4d4, Transformers , CUDA 13.0. MXFP4 requires your B200 run to establish runtime compatibility.
After downloading this snapshot, python verify_mtp.py /path/to/snapshot runs two prompts and requires positive draft-token metrics. A successful model load alone is not counted as an MTP pass. The script records generations and speculative decoding metrics.
