- Free allowance
- Not published. What is documented is capability rather than quota: the dataset center accepts file, folder, or archive uploads and auto-extracts archives server-side; public datasets require a license field before they can be published (so publishing is a two-step publish flow, not a raw PUT).

| Free tier | Not published. What is documented is capability rather than quota: the dataset center accepts file, folder, or archive uploads and auto-extracts archives server-side; public datasets require a license field before they can be published (so publishing is a two-step publish flow, not a raw PUT). OpenDataLab is the org behind the WanJuan corpus and mirrors COCO and similar multi-hundred-GB sets, so its scale class is genuinely multi-TB on the read side. unit TB; metered on unstated |
|---|---|
| Price | none stated |
| Limits |
Unverified quota. Known: public publication requires a license to be set (a metadata gate, not a storage gate); archives are auto-extracted, so extracted size counts. No per-file cap, retention, or rate limit published. |
| Identity | email email + likely +86 phone (Chinese platform). |
| Egress | Free for public datasets; anonymous downloads. No egress line found. Served from Chinese CDN endpoints. |
| Per-object cap | No per-file cap, retention, or rate limit published |
| Retention | not stated |
| Interface | s3-compatible, rest, cli rest |
| Tooling | Same openxlab toolchain (OpenDataLab runs on the OpenXLab 浦源 docs stack): pip install openxlab, openxlab dataset upload-file/-folder. Also opendatalab/opendatalab-python-sdk (60 stars) and an OpenDataLab CLI documented at opendatalab.com/docs/developers/数据集/数据集CLI. There is no S3 API. |
| Composes with | Per-dataset repos, unlimited count, free account. 50 GB-class datasets are the platform's normal unit, so N datasets x 50-200 GB. |
| Reliability | API endpoints on opendatalab.com timed out from this network (25 s, then 30 s) while HTML pages served fine — treat the programmatic surface as CN-network-dependent. |
