Clarifai Visual Search vs Yandex Vision OCR

Clarifai Visual Search lets people locate people, places, objects, topics, and products in images and videos without describing them with words. In ecommerce, shoppers can submit a photo to find similar products, identify purchasable items within rooms or outfits, and receive alternatives when an item is unavailable. Search can rank whole images by visual similarity or use detected regions for localized searches. The API supports semantic similarity retrieval, AI-generated vector embeddings, metadata filters, and combined conditions. One object-search workflow accepts SVG, PNG, JPG, or GIF files up to 800 by 400 pixels. Deployment is available through API, web, or self-hosted arrangements, including shared or dedicated cloud, a customer VPC, on-premise, and edge environments. Clarifai lists object detection, image classification, face recognition, OCR, and custom models. It also lists integrations such as LangChain, LlamaIndex, Databricks, Unstructured.io, CrewAI, and Vercel. Clarifai says customer data is private by default, is not used for training unless shared with the Community, and is covered by SOC 2 Type 2 compliance.

Yandex Vision OCR recognizes printed and handwritten text in images and PDF files. Its models cover general page text, multi-column layouts, handwriting, tables, Markdown text, and mathematical formulas. Document-template models can recognize passports, driver licenses, vehicle registration certificates, and license plates, and return template fields. The service is accessed through gRPC or REST APIs. Results arrive as JSON Lines and can include recognized text and language, page, block, line, word, and image positions, plus layout types such as titles, headers, footnotes, and lists. Supported formats are JPEG, PNG, and PDF. The API accepts files up to 10 MB and images up to 20 megapixels; asynchronous PDF requests can cover up to 200 pages. Results remain on the server for three days. Each successful image or PDF-page recognition counts as one billed unit, while server errors and incorrectly configured requests are not charged. Listed rates range from free for printed text and license plate recognition to $0.01, paid once for several document, handwriting, and table models, billed per unit without VAT. There is no free plan.
