inclusionAI-ZwZ2-27B-GGUF

ZwZ2-27B (inclusionAI/ZwZ2-27B) is an open-weight 27B-parameter vision-language model from inclusionAI’s Zooming-without-Zooming-v2 collection, built on Qwen/Qwen3.6-27B to connect evidence across image regions through comparison, matching, aggregation, and multi-step reasoning without inference-time zooming tools. Trained directly with Group Relative Policy Optimization (GRPO), without an additional supervised fine-tuning stage, it uses approximately 20,000 examples from inclusionAI/ZwZ2-RL-VQA, generated through the EvidenceConnect pipeline on SA-1B images. EvidenceConnect creates multi-region questions from 3–7 related regions, using privileged crops during data construction while training on full images with highlighted regions. Across 25 benchmarks spanning fine-grained perception, spatial reasoning, long-context visual understanding, multimodal agents, and general visual reasoning, ZwZ2-27B outperforms its Qwen3.6-27B base on all 25 benchmarks, raising equal-weighted accuracy from 55.52% to 60.51% (+4.99 points). Evaluation includes the 25 non-counting tasks of the MMLongBench* visual core, covering V-RAG, Image MM-NIAH, and VH-Multi.
