PP-OCRv6 Detection Module Outperforms VLMs on Text Localization Benchmarks

PaddlePaddle says its PP-OCRv6_medium text detector reached an 86.2% detection Hmean in benchmarks, versus 46.8% for Gemini-3.1-Pro and 38.3% for GPT-5.5. The detector's design uses RepLKFPN with 7×7 kernels to cut FPN neck parameters from 172K to 118K, auxiliary deep supervision heads on P2–P4, and Focal Loss paired with Dice Loss, which adds +1.15% Hmean in ablation.
