| # Model size and tensor precision |
|
|
| QEV is an independent decision model adaptation using the pinned Qwen3.5-2B backbone. |
| The QEV name does not change the architecture or upstream weight provenance. |

|
| ## Parameter counts |
|
|
| | Component | Parameters | |
| | --- | ---: | |
| | Vision backbone | 331,416,576 | |
| | Language backbone | 1,881,825,088 | |
| | Backbone used by QEV | 2,213,241,664 | |
| | Stored language LoRA | 7,815,168 | |
| | Option readout | 32,768 | |
| | Condition readout | 6,144 | |
| | Condition binding head | 138,304 | |
| | Stored adaptation/readout total | 7,992,384 | |
| | Model with unmerged adapters | 2,221,234,048 | |
| | Model after LoRA merge | 2,213,418,880 | |
|
|
| Counts come from the pinned `Qwen3_5Model` parameter structure and safetensors headers, |
| without allocating a second backbone on the GPU. LoRA weights merge into existing |
| backbone matrices, so they are not additional inference parameters after merging. |

| ## Dtypes and files |
|
|
| | Item | Precision / format | Size | |
| | --- | --- | ---: | |
| | QEV head checkpoint | safetensors; 307 tensors, all FP32 | 32,009,800 bytes (32.01 MB) | |
| | Upstream checkpoint file | safetensors; mostly BF16, 2,592 FP32 elements | 4,548,221,488 bytes (4.55 GB) | |
| | GPU inference backbone | BF16 | Hardware memory use also includes activations and runtime buffers | |
| | GPU decision readouts / binding | FP32 | Probabilities are computed through the existing calibrated runtime | |
| | CPU inference | FP32 | Higher weight memory use than the BF16 GPU path | |
|
|
| The upstream file contains 2,274,069,824 tensor elements, including 60,828,160 MTP |
| elements that the QEV encoder does not use. This explains the difference between the |
| download's tensor count and the 2.213B backbone used for inference. QEV does not ship |
| an INT8 or INT4 quantized checkpoint. |
|
|
| The Python wheel is code, not the complete neural network. `qev download` retrieves |
| the 32 MB decision checkpoint and the approximately 4.55 GB upstream weights separately. |
| Historical evidence in the complete release ZIP makes that ZIP larger than the primary |
| head checkpoint; these are different download sizes. |
