Alibaba Cloud PAI iTAG is a data-labeling platform for image, text, video, audio, and multimodal datasets. Image tasks include classification, object detection, OCR, table recognition, and semantic segmentation; official templates also cover image-text explanation, conversation ranking, visual question answering, and video OCR. Teams can select official or tenant templates, or create custom ones for their own labeling requirements. A labeling job combines an OSS-backed dataset and template with labels, subtasks, checks, labelers, and reviewers. Manual labeling on the platform is free, with OSS storage and data transfer billed separately; selected large-model templates are currently free. Data must be in Alibaba Cloud OSS, and the workspace and bucket must be in the same region. Imports require an index file rather than a direct path to a raw-file folder. From August 1, 2026, iTAG 1.0 is allowlist-only and in maintenance mode. Existing customers with prior tasks or datasets can continue using current features; new users seeking AI-powered automatic dataset labeling are directed to Multimodal Data Management.
Who it is for
iTAG may suit existing Alibaba Cloud customers who need human labeling workflows for supported data types and have prior tasks or datasets. New users seeking AI-powered automatic dataset labeling are directed to Multimodal Data Management.
