What changed
- Parent GPTQ-Pro artifact:
XReyRobert/Qwopus3.6-27B-v2-GPTQ-Pro-v1
- Source for restored MTP tensors:
Jackrong/Qwopus3.6-27B-v2
- Restored
mtp.* tensors: 15
- Restored MTP dtype counts:
{"bfloat16": 15}
- Local tensor shard size after patch:
18.22 GiB total safetensors
Practical note
This is meant for loader and vLLM speculative-decoding experiments. Previous
testing on 1x RTX 3090 showed that restoring MTP made draft acceptance work, but
did not improve throughput versus the non-MTP GPTQ-Pro baseline. The likely
bottleneck was vLLM/GPTQ-Marlin speculative path overhead rather than MTP tensor
precision.
For practical long-context 1x RTX 3090 serving, the non-MTP baseline remains the
recommended artifact:
XReyRobert/Qwopus3.6-27B-v2-GPTQ-Pro-v1
Validation status
Structural checks performed during patch creation:
model.safetensors.index.json contains restored mtp.* keys.
- All indexed shard files exist locally.
- The added MTP shard is a standalone safetensors file.
config.json records mtp_num_hidden_layers >= 1.
Runtime serving validation is still required before treating this as a working
MTP deployment artifact.
