visionservex 1.3.0

A permissive-license-aware framework for serving modern computer vision models locally and over Cloudflare Tunnel.

VisionServeX

Accuracy-aware computer vision model gateway — honest, local-first, and privacy-respecting.
Serve modern CV models on your machine. Local-only by default. No data retained.

What is VisionServeX?

VisionServeX is an open-source, permissive-license-aware Python framework for running modern computer vision models locally and exposing them through a stable HTTP API. It works as a local model gateway: start it once, call any supported model through one clean API.

Accuracy-aware and scientifically usable:
Every model carries an explicit accuracy taxonomy label: demo_fast, production_recommended, accuracy_grade, experimental_sota, expert_sidecar, external_api, or unavailable_with_reason. The recommender, benchmark tools, and registry are aligned to these labels so you always know what tier you are running. Real AP50/mAP50:95 is computed when you provide an annotated dataset.

Honesty policy:
VisionServeX does not claim to beat Ultralytics globally. The benchmark-competitiveness tool is designed to reveal the honest truth. If YOLO wins, it will say so.

Privacy-first design:

• Binds to 127.0.0.1 by default — nothing leaves your machine.
• Images are decoded in memory for inference and never written to disk by default.
• No data is retained between requests by default.
• Log redaction removes tokens, base64, and API keys from all output.

⚠️ No end-to-end encryption claimed. VisionServeX cannot provide E2E encryption in the cryptographic sense — the inference server must see plaintext image tensors to run models. We provide local-first processing, no-retention defaults, optional encryption-at-rest for job metadata, and auth for public mode. See docs/privacy.md.

Quickstart (CPU, 5 minutes)

pip install 'visionservex[server,hf,rfdetr]'

visionservex getting-started      # personalized guide
visionservex pull dfine-s-o365-coco   # accuracy-grade detection, CPU-capable
visionservex serve                     # http://127.0.0.1:8080

curl -F "image=@image.jpg" -F "model_id=dfine-s-o365-coco" \
     http://127.0.0.1:8080/detect | jq

For a quick demo (smallest model):

visionservex pull rfdetr-nano          # demo_fast, CPU-capable
visionservex predict rfdetr-nano image.jpg

---

Python Client

from visionservex import Client, VisionModel

# Direct inference (local, no server needed)
result = VisionModel("dfine-s-o365-coco").predict("image.jpg")   # accuracy_grade
result = VisionModel("rfdetr-nano").predict("image.jpg")          # demo_fast

# Via local gateway
client = Client("http://127.0.0.1:8080")
result = client.detect("dfine-s-o365-coco", "image.jpg")
result = client.grounded_segment("grounded-sam2", "image.jpg", prompt="car, person")
result = client.classify("swinv2-tiny", "image.jpg")

---

Model Taxonomy

Every model in the registry now carries an explicit model_category label.

Category	Meaning	Examples
demo_fast	Quick demo, small, not for accuracy benchmarks	dfine-n, rfdetr-nano, rfdetr-seg-nano, grounding-dino-tiny
production_recommended	Solid accuracy, ready for real use	rfdetr-small, rfdetr-seg-small, swinv2-tiny, sam-vit-base
accuracy_grade	Tracked for AP benchmarks; explicitly wired	dfine-s-o365-coco, dfine-m/l/x-o365-coco, rfdetr-medium/large, grounding-dino-swin-b
experimental_sota	Claims SOTA but not fully verified in this build	deim-s/m, deimv2-s/m, rtdetrv4-s/m/l/x, maskdino-r50-coco
expert_sidecar	Requires expert setup (OpenMMLab, custom ops)	rtmpose-*, internimage-*, co-dino-*
external_api	API-gated upstream; not self-hostable	grounding-dino-1.5/1.6
unavailable_with_reason	Blocked; honest reason documented	rfdetr-seg-large/xlarge/2xlarge
utility	Mock / built-in / test helpers	mock-detect, mock-classify, …

Key rule: demo_fast models are not used to claim competitiveness with YOLO. Use accuracy_grade variants for AP benchmarks.

Competitiveness Benchmark

# Synthetic mode (latency + detection health, no ground truth needed)
visionservex benchmark benchmark-competitiveness \
  --models dfine-s-o365-coco,rfdetr-small \
  --max-images 20 --device auto

# Real AP mode (AP50/mAP50:95 with YOLO-format annotated dataset)
visionservex benchmark benchmark-competitiveness \
  --models dfine-s-o365-coco,rfdetr-small,ultralytics:yolo11n \
  --dataset yolo:/path/to/coco128 \
  --max-images 100 \
  --out reports/ap_benchmark

# COCO JSON format
visionservex benchmark benchmark-competitiveness \
  --models dfine-s-o365-coco,rfdetr-small \
  --dataset coco-json:/data/coco/images:/data/coco/annotations/instances_val2017.json \
  --max-images 500

Real AP/mAP is computed with COCO-style 101-point interpolated PR curves when --dataset is provided. Results are exported as JSON + CSV. The tool is honest — if YOLO wins, it will say so.

Note: Accuracy-grade models are separate from demo models. Do not judge VisionServeX by dfine-n or rfdetr-nano — use dfine-s-o365-coco or rfdetr-small for AP comparison.

Detection, segmentation, classification, pose, OBB, and open-vocabulary tasks need different metrics. Non-detection benchmark tools return BENCHMARK_NOT_IMPLEMENTED with honest roadmap information (roadmap: v1.4).

Debug Output

Before declaring a checkpoint weak, run the postprocessing audit:

visionservex debug-output dfine-s-o365-coco image.jpg
visionservex debug-output dfine-s-o365-coco image.jpg --threshold 0.01 --json

Reports: score histogram, label histogram, first 10 boxes, invalid boxes, unmapped labels, preprocessing notes.

---

Model Recommender

# By goal (v1.2.0)
visionservex recommend --task detect --goal accuracy
visionservex recommend --task detect --goal fastest_demo
visionservex recommend --goal best_segmentation
visionservex recommend --goal best_open_vocab

# By task and hardware
visionservex recommend --task detect --device cpu
visionservex recommend --task detect --device cuda --vram 8

For --goal accuracy --task detect, the recommender surfaces dfine-s/m-o365-coco and rfdetr-small/medium, not nano variants.

Temporary Colab GPU Worker (optional)

Run VisionServeX on a Google Colab GPU as a short-lived remote worker. Good for demos and benchmarks, not for production — Colab sessions can disconnect at any time.

# Inside a Colab notebook:
!pip install -U 'visionservex[server,hf,rfdetr]'
!visionservex colab doctor
!visionservex gateway start --profile colab-gpu-worker

A copy-paste notebook lives at examples/colab/VisionServeX_Colab_GPU_Worker.ipynb. Full guide: docs/colab_gpu_worker.md.

Installation

pip install visionservex                        # base (no heavy deps)
pip install 'visionservex[server]'              # + HTTP API server
pip install 'visionservex[hf]'                  # + HF Transformers (D-FINE, GD, SwinV2, SAM, SAM2, OneFormer)
pip install 'visionservex[rfdetr]'              # + RF-DETR and RF-DETR-Seg
pip install 'visionservex[server,hf,rfdetr]'    # full recommended

OpenMMLab (RTMPose, RTMDet-R, Co-DINO, InternImage): Docker sidecar or pip install openmim && mim install mmengine mmcv mmpose. See docs/openmmlab_expert_models.md.

---

Known Limitations

• D-FINE COCO-only variants (dfine-s-coco etc.): Point to HF repos that may not exist yet. Use dfine-s-o365-coco (Objects365+COCO) for guaranteed availability.
• DEIM / RT-DETRv4: Registered as experimental_sota but not wired. Blockers documented per-model in the registry.
• AP50/mAP benchmark: The benchmark-competitiveness tool reports latency and detection health only. Full AP evaluation requires ground-truth COCO annotations not bundled with VisionServeX.
• OpenMMLab (RTMPose, RTMDet-R/R2, Co-DINO, InternImage): Requires the OpenMMLab toolchain and manually-obtained checkpoints. Returns CHECKPOINT_REQUIRED structured error — no fake output.
• TensorRT: ONNX export works for SwinV2. TensorRT engine build requires trtexec.
• Apple MPS: Implemented but not maintainer-verified.

GPU: CUDA verified on RTX 5080 for 6+ model families. Run visionservex gpu smoke-test on your hardware.
MPS (Apple Silicon): Implemented, not maintainer-verified. See docs/gpu_validation.md.
VRAM safety: Desktop GPU guard reserves 3 GB for GUI/system. GPU tests run serially by default. See docs/gpu_safety.md.
