| # LibreTinyFormerm |
|
|
| TinyFormer-M-PBM detection weights, repackaged for LibreYOLO. |
| TinyFormer ("TinyFormer: Preserving Tiny Objects in YOLO-DETR Hybrid |
| Real-time Detectors", arXiv:2605.25046) is a DEIMv2-derived YOLO-DETR hybrid |
| specialised for tiny objects via a Spatial Semantic Adapter and a 4-scale |
| Parallel Bi-fusion neck. This size runs on the DEIMv2-distilled ViT-Tiny+ tower (DINOv3-distilled). |
|
|
| Reported COCO val2017 mAP50-95: **53.7**. |
|
|
| ## Usage |
|
|
| ```python |
| from libreyolo import LibreYOLO |
| |
| model = LibreYOLO("LibreTinyFormerm.pt") # auto-downloads from this repo |
| results = model.predict("image.jpg") |
| ``` |

| The backbone parameters derive from |

| Because this checkpoint bundles DINOv3-derived parameters, the combined |

|
|
| ## Modifications |
|
|
| Checkpoint metadata wrapping only — learned parameters are unchanged (the EMA |
| weights of the released solver checkpoint). The wrapper adds ``model_family``, |
| ``size``, ``nc``, and ``names`` fields so the unified ``LibreYOLO()`` factory |
| routes correctly without filename heuristics. |
| See `weights/convert_tinyformer_weights.py` in the |
| [LibreYOLO source repository](https://github.com/LibreYOLO/libreyolo). |
