Mozilla has unveiled open-source tools to help developers build ethical AI datasets and avoid training models on copyrighted material.
The reliance of many popular large language models (LLMs) on vast datasets scraped from the internet, often encompassing copyrighted works used without permission, presents a significant ethical and legal challenge.
A growing contingent within the developer community believes creating high-quality, ethically sound alternatives is not only possible but necessary. This launch directly supports that movement.
The new toolkits – products of a year-long collaboration with EleutherAI – provide developers with practical workflows, code, and demonstrations hosted on the Mozilla.ai Blueprints platform (a space dedicated to helping developers prototype AI applications using open-source components.)
Ayah Bdeir, Senior Advisor for AI Strategy at the Mozilla Foundation, said: “Just like open-source software in its early days, today’s open data ecosystem depends on community contributions and shared values.
“These toolkits are part of an effort to create common resources, make dataset creation easier, and promote the infrastructure needed for ethical AI development. Our partnership with EleutherAI is grounded in our shared commitment to advance this mission.”
- Toolkit 1: Self-hosted audio transcription with Whisper
The first blueprint focuses on transcribing audio files locally. It leverages open-source Whisper models through Speaches, a self-hosted server engineered to function similarly to the commercial OpenAI Whisper API.
This toolkit provides developers with a privacy-centric alternative, crucial when dealing with sensitive or private audio data that shouldn’t be processed by third-party cloud services.
Recognising real-world developer needs, the setup process is streamlined for deployment using either Docker containers or standard Command Line Interface (CLI) instructions. This approach gives developers full control over their data during the transcription process, a vital capability for projects requiring high levels of confidentiality or regulatory compliance.
- Toolkit 2: Converting diverse documents to Markdown
The second toolkit tackles the challenge of standardising unstructured documents for AI training. It introduces Docling, a powerful command-line utility designed to convert various file formats – including PDFs, DOCX, HTML, and others – into clean Markdown text.
Docling incorporates robust Optical Character Recognition (OCR) for scanned documents or images containing text and includes sophisticated image-handling capabilities. Its primary function is to facilitate the creation of open-text datasets suitable for diverse downstream applications, such as training bespoke language models or building Retrieval-Augmented Generation (RAG) systems.
The toolkit emphasises accessibility and versatility, notably featuring batch-processing capabilities to handle large volumes of documents efficiently.
Collaborative research helping developers build ethical AI datasets
These practical tools stem from a sustained partnership between Mozilla and EleutherAI. This collaboration included convening 30 leading academics and practitioners from prominent open-source AI startups, non-profit research labs, and civil society organisations.
The group focused on defining best practices for dataset creation within the open LLM community, culminating in the ‘Towards Best Practices for Open Datasets for LLM Training’ research paper. The toolkits serve as actionable resources to help developers implement the principles outlined in the paper.
The current AI landscape often sees the threat of litigation cited as a reason to minimise transparency regarding training data, which hinders both scrutiny and innovation.
Proponents argue that building open-access, responsibly curated, and openly licensed datasets is the necessary countermeasure. While achieving this requires collaboration across legal, technical, and policy domains – alongside investment in standards and digitisation efforts – the fundamental challenge remains: creating such datasets is difficult.
Stella Biderman, Executive Director at EleutherAI, commented: “Openness and transparency is the future of AI. By putting practical tools into the hands of developers, we’re helping build high-quality, openly licensed datasets that form the foundation for more trustworthy, transparent, and interpretable AI systems.”
The toolkits from Mozilla and EleutherAI represent a crucial, practical contribution towards simplifying the creation of ethical datasets, empowering developers to build the next generation of AI on a more responsible foundation.
