Model overview
An int4 weight-only (W4A16) quantization of Qwen/Qwen3.8-27B, made with Intel AutoRound and packaged in compressed-tensors for vLLM. The weights are int4 and the activations stay BF16, so it runs on any Ampere-or-newer NVIDIA GPU through the Marlin int4 kernel — no Blackwell needed. It's about 19.5 GB on disk, down from roughly 52 GB at BF16. This build is aimed at non-Blackwell GPUs. If you have a Blackwell card (RTX 50-series, B200, DGX Spark), the NVFP4 (W4A4) sibling uses the FP4 tensor cores and will be faster. Accuracy notes are in the Evaluation section below. - **Base model:** `Qwen/Qwen3.8-27B` — a hybrid **GatedDeltaNet (linear-attention) + full-attention** multimodal decoder (64 layers: 48 linear-attn + 16 full-attn) with a vision tower; 262K context. - **Quantization:** int4 **W4A16** (weight-only, group size 128) on the language-decoder `Linear` layers, **except** the two tiny per-layer recurrence-control projections (`in_proj_a`, `in_proj_b`) which stay BF16. - **Kept BF16:** `linear_attn.in_proj_a` / `in_proj_b`, the entire `visual.*` vision tower, the `mtp` head, and `lm_head`. - **Format:** compressed-tensors (`pack-quantized`), auto-detected by vLLM (Marlin int4). - **Quantizer:** Intel AutoRound (arXiv:2309.05516), SignRound block reconstruction.

Limitations & considerations
Sources are insufficient to establish specific limitations. Verify task performance, latency, data policies, licensing and version lifecycle.
Source prices & cost analysis
Prices vary by channel, region and configuration. Channel quotes are listed independently and are not treated as a single official provider price.

Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
