Zero Hand-Fixed Boxes: DeepSeek V4.1 Flash Does Local Object Detection Cross-Checked by RF-DETR

MaziyarPanahi · x · 2026-09-15

A hands-on demo of object detection with DeepSeek V4.1 Flash: the author fed it 10 completely different photos, then kept only the boxes that a locally running RF-DETR model agreed with. Not a single box needed moving or hand-fixing, and the whole pipeline ran fully local.

The post includes four favorite examples — a lightweight trick combining a large model's perception with a dedicated detector as a consistency filter, no labeling required.
