Qwen3.5-0.8B-INT-W8A8
casperhansen/Qwen3.5-0.8B-INT-W8A8
Qwen3.5-0.8B-INT-W8A8 is a machine learning model from casperhansen. Use it for the machine learning task on the model card, and read the license before you ship it in a product. The card lists the license as apache-2.0.
INT8 W8A8 quantization of Qwen/Qwen3.5-0.8B, produced for development purposes with the simplest possible method: round-to-nearest (RTN) weights — no GPTQ, no calibration data.

Qwen3.5-0.8B-INT-W8A8
INT8 W8A8 quantization of Qwen/Qwen3.5-0.8B,
produced for development purposes with the simplest possible method:
round-to-nearest (RTN) weights — no GPTQ, no calibration data.
Quantization scheme (compressed-tensors W8A8 preset)
| bits | type | strategy | scales | |
|---|---|---|---|---|
| weights | int8 | symmetric | per-channel | static, RTN via memoryless_minmax |
| activations | int8 | symmetric | per-token | dynamic (computed at runtime) |
Ignored (kept in bf16): ['lm_head', 're:model\\.visual\\..*'] — the vision tower stays full-precision;
lm_head is tied to the input embeddings.
