Qwen3.6-27B-NVFP4-GGUF

Qwen3.6-27B from Alibaba's Qwen team is a 27B-parameter dense multimodal model with an integrated vision encoder, 64 layers, and a native 262K-token context window extendable to 1M+ via YaRN. It delivers strong agentic coding, repository-level reasoning, and frontend development capabilities, outperforming the previous Qwen3.5-397B-A17B flagship on SWE-bench Verified (77.2), Terminal-Bench (59.3), and SkillsBench (48.2). It also scores 87.8 on GPQA-Diamond and 66.1% on BFCL-V4 for tool calling. Hybrid thinking modes preserve reasoning across multi-turn workflows. It supports vLLM, SGLang, and Unsloth, with GGUF quantization enabling local deployment, and is released under Apache-2.0.

MTP β€” Speculative Decoding: Yes

Multi-Token Prediction (MTP) GGUF is a specialized GGUF model file format extension that integrates speculative decoding directly into the model weights to significantly accelerate local inference. Unlike traditional speculative decoding which requires a separate, smaller "draft" model, MTP GGUF files include additional output heads within the main model architecture that predict multiple future tokens in a single forward pass.
