GCP Vision AI cost: per image, by feature

Quick answer

Cloud Vision bills per image per feature (label detection, face detection, text/OCR, object localization, safe-search, and others), each priced separately, so requesting several features on one image bills for each, with a monthly free tier and tiered volume discounts. Cost scales with images times features, so requesting only the features you need and caching results are the levers.

Google Cloud Vision analyzes images for labels, faces, text, objects, and more. It is priced per image per feature, so the unit is not the image but the image-feature pair. Requesting several features on one image bills for each, which is where cost grows if you request more analysis than the use case needs.

Per image, per feature

Feature (examples)	Billing
Label detection	Per image
Text detection / OCR	Per image
Face / object / safe-search	Per image, each feature separate

Each feature is billed per image, at tiered rates that fall with volume, with a monthly free tier. So an image analyzed for labels, text, and objects bills three times, once per feature. Requesting only the features the use case needs avoids paying for analysis you do not use.

Controlling Vision AI cost

Request only the features each use case needs (do not run every feature on every image), cache results so you do not re-analyze the same image, pre-filter to skip irrelevant images before calling the API, and use the free tier for development. Because billing is per image per feature, the levers are feature selection and caching, exactly as with Rekognition and Azure AI Services.

FAQ

How is GCP Cloud Vision priced?

Per image per feature (label detection, text/OCR, face detection, object localization, safe-search, and others), each priced separately, so requesting several features on one image bills for each. Rates are tiered and fall with volume, with a monthly free tier. Cost scales with images times features requested.

How do I reduce Cloud Vision cost?

Request only the features each use case needs rather than running every feature on every image, cache results to avoid re-analyzing the same image, pre-filter to skip irrelevant images before calling the API, and use the free tier for development. Feature selection and caching are the main levers.

Does requesting multiple Vision features cost more?

Yes. Each feature, label detection, text detection, face detection, object localization, is billed per image separately, so an image analyzed for three features bills three times. Requesting only the features the use case requires, rather than all of them, avoids multiplying the per-image cost.

Does Cloud Vision have a free tier?

Yes, a monthly free allowance per feature that covers low-volume usage and testing. Beyond it you pay per image per feature at tiered rates that fall with volume. The free tier makes low-volume experimentation essentially free across the features.

What drives Cloud Vision cost?

The number of images times the number of features requested per image. High image volume and requesting many features per image both multiply cost. Re-analyzing the same images without caching also wastes calls. Requesting only needed features and caching results keeps cost proportional to real need.

Does C3X estimate Cloud Vision cost?

Cloud Vision cost is driven by images and features analyzed, which are usage inputs. C3X prices the surrounding infrastructure, and you model your image volume and the features each use case needs to estimate the per-image-per-feature charges.
