Qwen3.8-27B-GPTQ-W4A16

Model overview

📦 18.1 GiB · 2.8× smaller compressed-tensors · int4 g128 sym 🧬 calibrated at ctx 32,768 ⚡ MTP bundled · 1.71× decode 👁️ Text + Image · vision 3/3 🏅 tool-calling = bf16, turn for turn 🏗️ vLLM 0.27.1 ⚡ What this is A compressed-tensors W4A16 (GPTQ, int4 group-128 symmetric) quantization of Qwen/Qwen3.8-27B that vLLM serves directly — no conversion, no custom runtime, quantization auto-detected from config.json . Calibrated on 4.26M tokens of real agentic-coding sessions packed at 32K context. Sibling of the GGUF ladder , same corpus: this one for vLLM , the GGUF for llama.cpp / Ollama / LM Studio. ⚡ Speculative decoding + vision, both bundled The trained MTP draft head ships inside the checkpoint — one --speculative-config flag, no second file, 1.71× decode at 71.2% acceptance . The vision tower ships too, kept at bf16: shown a synthetic test image it named the colour, shape and position of all three shapes correctly, unprompted detail included ("inverted triangle, base horizontal at the top"). Both are additive — drop the flags and you are back to the identical text model.
