Description

Hi,

I’m currently using Unsloth Studio to fine-tune unsloth/ Whisper Large v3, and I have a question regarding dataset ingestion. My dataset consists of audio files stored privately on AWS S3 along with their corresponding transcriptions. I’d like to know whether Unsloth Studio supports direct integration with S3 (e.g., via bucket paths, IAM roles, or signed URLs) during the dataset upload step. At the moment, I’m unsure if there is a built-in way to connect an S3 bucket or if all data must first be downloaded locally to the instance. Could you clarify if this feature exists, is planned, or if there is a recommended workaround for securely using private S3-hosted audio datasets within Unsloth Studio?

Thank you for helping..

Research direction
Review existing dataset upload code in Unsloth Studio (likely in backend/frontend files) and AWS SDK integration. Check if any existing PRs or issues discuss S3 support. Consider implementing a new data source plugin that accepts S3 bucket paths or signed URLs, following patterns from other cloud storage integrations.
