-# RF-DETR Base — GGUF for rfdetr.cpp
-
-GGUF-format weights of [Roboflow RF-DETR Base](https://github.com/roboflow/rf-detr) (detection variant) for use with [rfdetr.cpp](https://github.com/mudler/rt-detr.cpp), a C++/ggml implementation that matches the upstream PyTorch model on CPU.
-
-This repo contains all four standard quantizations of this variant. **F16 is the recommended default** — same accuracy as F32, 1.85× smaller, and typically the fastest on modern CPUs thanks to ggml's F32×F16 matmul fast path.

-| File | Quant | Size (MB) | Recall @ IoU 0.5 | Recall @ IoU 0.95 | Mean \|Δscore\| | Latency (median ms, T=8) |
-|---|---|---:|---:|---:|---:|---:|
-| `rfdetr-base-f32.gguf` | F32 | 119.2 | 1.0000 | 0.9890 | 0.0080 | 144.0 |
-| `rfdetr-base-f16.gguf` ← **recommended** | F16 | 64.2 | 1.0000 | 0.9890 | 0.0082 | 136.1 |
-| `rfdetr-base-q8_0.gguf` | Q8_0 | 38.5 | 1.0000 | 0.9890 | 0.0091 | 145.7 |
-| `rfdetr-base-q4_K.gguf` | Q4_K | 31.5 | 0.9531 | 0.8794 | 0.0196 | 166.3 |
-
-All accuracy numbers are computed against the upstream PyTorch reference (`rfdetr 1.7.0`) on 7 COCO val2017 images at threshold 0.5. Latency is measured with `rfdetr-cli bench` (8 iters + 3 warmup) at T=8 threads on a single AMD Ryzen 9 9950X3D image (`coco_kitchen.jpg`, 640x427).

-## Architecture
-
-- Backbone: DINOv2-small
-- Input resolution: 560×560
-- Patch size: 14
-- Decoder layers: 3
-- Object queries: 300
-- Task: object detection (boxes only)
-
-## Quantization notes
-
-- **F32** — full-precision reference, ~120 MB. Bit-exact PyTorch parity.
-- **F16** — matmul-multiplicand weights only; LayerNorms, conv kernels, embeddings, biases, and layer-scale gammas stay F32. Lossless on this model and consistently the fastest variant on CPU.
-- **Q8_0** — best size/accuracy tradeoff under F16; ~3× smaller than F32 with effectively identical detections.
-- **Q4_K** — smallest practical quant. Rows with `ne[0] % 256 != 0` (the decoder's 128-dim MLP halves, 60 tensors) silently fall back to Q8_0 per ggml's quantizer logic — net compression is still ~3.8× over F32. Use only when the size budget is tight; expect a measurable Recall@0.95 drop relative to F16/Q8_0 (see file table above).

-## Usage
-
-```bash
-# 1. Clone + build rfdetr.cpp
-git clone https://github.com/mudler/rt-detr.cpp
-cd rt-detr.cpp
-cmake -B build -DRFDETR_BUILD_CLI=ON && cmake --build build -j
-
-# 2. Download a quant (F16 recommended)
-hf download mudler/rfdetr-cpp-base rfdetr-base-f16.gguf --local-dir models/
-
-# 3. Run detection
-build/bin/rfdetr-cli detect \
-    --model models/rfdetr-base-f16.gguf \
-    --input my_image.jpg \
-    --threshold 0.5 --threads 8 \
-    --output detections.json
-```

-## Accuracy methodology
-
-All accuracy metrics are computed against the upstream PyTorch reference (rfdetr 1.7.0) on 7 COCO val2017 images at threshold 0.5. Each detection match uses greedy Hungarian-style assignment by IoU (≥ 0.5 lenient, ≥ 0.95 strict) with class equality required.
-
-See [BENCHMARK.md](https://github.com/mudler/rt-detr.cpp/blob/main/BENCHMARK.md) and [`benchmarks/results/accuracy_sweep.json`](https://github.com/mudler/rt-detr.cpp/blob/main/benchmarks/results/accuracy_sweep.json) for the full sweep across all 32 (variant × quant) cells.
