DSH Vision Tiler: A Full-Coverage Image Tiling Plugin for the DeepSeek Harness Vision Model

DSH Vision Tiler is a vision plugin for DeepSeek Harness that uses image tiling to overcome the limited 384-token budget of vision models. It breaks high-resolution images into coverage tiles and detail crops, with support for overlapping seams and content-aware cuts, ensuring 100% geometric coverage. The plugin is implemented in pure JavaScript and WebAssembly, supports multi-format decoding, and substantially improves model recognition accuracy for dense documents and charts through bounded batch processing. Installation requires Node.js 22+ and is currently version-locked via GitHub.
