Upload a Dataset

Upload a dataset to the Portex Datalab.

The first step to listing a data product on the Datalab is uploading a dataset. From the Data Studio, go to Datasets and click "Add new item."

Upload Options

Upload a File

Upload a dataset directly to the Datalab. Accepted formats:

• .parquet for tabular data

• .tar.gz or .gz for multi-modal bundles

Maximum size: 20 GB. Enter a dataset name and an init commit message (max 300 characters), then drag and drop your file or click "Choose file."

External Dataset

If your data is hosted externally (e.g., an S3 bucket), select "External Dataset" and provide the connection type and estimated size. External datasets are verified at the time of purchase.

Eval Dataset

To upload an eval dataset bundle (tasks.json, answers.json, reference files), see Importing an Eval.

After Upload

Your dataset appears in the Data Studio under the Datasets tab. From here, you can edit the dataset name, upload a new version, or delete it.

To make the dataset available for purchase, proceed to Create a Listing.
