## 總覽

customvision.ai is the home of Microsoft's Custom Vision, a computer vision service that lets you train your own image classification and object detection models by uploading and labeling a handful of examples. You build the model in a browser-based interface, evaluate its accuracy with live metrics, and then consume it from your own applications through REST APIs or exported models.

## 價格與方案

Custom Vision uses a freemium model tied to Microsoft's Cognitive Services. A free tier covers a limited number of transactions, images and projects for experimentation, while production usage is billed per prediction, per training hour and per stored image through an Azure subscription. Check the Azure AI Custom Vision pricing page for current rates.

## 關鍵功能與能力

- **Label, train, evaluate in one loop:** Upload your own labeled images or use assisted tagging, train the model, then read precision and recall metrics on a held-out set before deciding to publish.
- **Classification and object detection:** Handle two different problems: multiclass or multilabel image classification, and object detection that returns bounding boxes for recognized objects with confidence scores.
- **Simple REST prediction API:** Published models expose an HTTP endpoint you can call from any language or platform; send an image and receive predicted tags, probabilities and boxes as JSON.
- **Exportable models:** Export trained models for CoreML, TensorFlow, ONNX, Docker and other formats when you need to run inference on-device or in your own infrastructure.
- **Iteration and versioning:** Keep multiple iterations of a model side by side, compare their performance, and promote the best one to production without retraining from scratch.

## 主要使用情境

- **Add image tagging to an app (Application developer):** Upload a few hundred labeled photos, train a classifier, and call the prediction endpoint to auto-tag user-uploaded images inside your product.
- **Build visual defect detection (Manufacturing or QA engineer):** Train object detection on photos of good and defective parts, then run a local or cloud model to flag anomalies on a production line.
- **Recognize products and assets (Retail or field operations):** Teach a model to identify SKUs, shelf conditions or equipment, and embed recognition into a mobile or web workflow.
- **Prototype a vision model quickly (Researcher or student):** Use the free tier and browser portal to test a computer vision idea with a small image set before committing engineering time.

## 優勢

- Very low barrier to entry — labeling, training and evaluation all happen in the browser
- Two model types (classification and object detection) with confidence scores in one service
- Prediction via a plain REST API, so it slots into almost any stack
- Model export options for on-device and self-hosted inference
- Free tier makes it possible to evaluate end to end before spending anything

## 限制

- Requires a Microsoft/Azure account and a provisioned Azure AI Vision resource for a live endpoint
- Only vision tasks are covered — no text or multimodal reasoning
- The customvision.ai portal is legacy-facing, and some Azure documentation is the only up-to-date source for provisioning
- Accuracy depends heavily on getting enough well-labeled examples per class
- Costs scale with prediction volume, which can surprise teams at high traffic

## 常見問題

### What is customvision.ai exactly?
It is the web portal for Microsoft's Custom Vision service, part of Microsoft Cognitive Services and now grouped under Azure AI. You upload labeled images, train a custom classifier or object detector, and publish it as a REST endpoint.

### Is it an OpenAI product?
No. Custom Vision is developed and operated by Microsoft, not OpenAI. OpenAITools lists it as an independent third-party AI tool.

### Does it cost anything to start?
There is a free tier intended for experimentation, within limits on transactions, images and training hours. Beyond those limits usage is billed through an Azure subscription per prediction, per training compute and per stored image.

### Can I run the model without calling the cloud?
Yes, in many cases. Trained models can be exported to formats such as ONNX, TensorFlow, CoreML or a Docker container so you can run inference locally or on-device.

### Do I need machine learning expertise?
Not for basic use. If you can sort images into folders with labels, you can train a first model. Domain knowledge about which classes matter and clean labeling matter more than ML background.
