Model overview
A **W4A16 (INT4 weight, FP16 activation) quantization** of `Qwen/Qwen3.6-27B`, produced with Intel's AutoRound. - **Base**: Qwen3.6-27B (27B dense VLM, Apr 21 2026) - **Quant**: INT4 W4A16, group_size 128, symmetric - **Tool**: `auto-round` (default recipe, 200 iters, torch.compile) - **Size**: 18 GB (down from ~54 GB BF16) — **3x reduction** - **MTP preserved**: The native Multi-Token Prediction head is kept in BF16, enabling **native speculative decoding** in vLLM (≈90% draft acceptance in our tests, ~2x throughput) - **Accuracy**: Default AutoRound recipe preserves quality well; layer-norm weights, router layers, RMSNorm, `linear_attn.in_proj_a/b`, and MTP's fusion `fc` are kept unquantized (they're small and benefit from full precision) Requires vLLM that supports Qwen3_5 MTP (most recent nightlies — tested with `eugr/spark-vllm-docker` fork `0.19.1rc1.dev39+g7055d32a7`):

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.
