Overview
Its ROOTS training corpus included natural and programming languages, making it a prominent open-access research model.
Deep Dive
The BigScience paper describes BLOOM as a decoder-only Transformer with 176 billion parameters. It was trained on ROOTS, a corpus assembled from hundreds of sources in 46 natural languages and 13 programming languages. The collaboration released the model and code under the Responsible AI License and documented data and training choices. Its open-access release supports research, but does not remove the need to consider the license, model limitations, or the represented language distribution.
Real-World Implementation
Generating and completing text across dozens of languages, including ones underserved by commercial models
Serving as an open research baseline for studying bias, multilingual transfer, and scaling behavior
Fine-tuning into task-specific or instruction-following variants such as BLOOMZ for non-English communities
Providing a fully documented model for academics studying training data provenance and responsible AI licensing
The Future of BigScience and the BLOOM Model
BigScience demonstrated that large-scale, openly governed AI is possible, and its model influenced later open releases and the broader push for transparency. Future multilingual work will likely build on its lessons in data documentation and inclusive language coverage, while newer, more efficient models have surpassed BLOOM on raw capability. Its lasting legacy is the norm of publishing model cards, data statements, and responsible licenses, plus proof that public compute can train frontier-scale models.
Putting it into practice
Why it matters
- Vendor strategy. Vendor roadmaps influence what features your team can build next.
- Cost and budget. Commercial terms and deployment options affect long-term cost and risk.
- Risk and safety. Company incentives shape product defaults, safety posture, and openness.
Watch out for
- Launch announcements may outpace stability in real production workflows.
- API pricing or policy shifts can break assumptions overnight.
- Single-vendor dependency increases lock-in and migration costs.
Next steps
- Evaluate providers using your own tasks and datasets.
- Review privacy, security, and legal terms before integration.
- Maintain a fallback plan across models or vendors.
- Monitor release notes so roadmap changes do not surprise teams.

BLOOM is a 176-billion-parameter model, placing it on a similar scale to GPT-3.
How many natural languages was BLOOM trained to handle?
BLOOM's ROOTS training corpus covered 46 natural languages plus 13 programming languages.
Which organization coordinated the BigScience collaboration?
Hugging Face coordinated BigScience, a workshop of more than 1,000 volunteer researchers.
Where was BLOOM trained?
BLOOM was trained on the Jean Zay supercomputer in France, demonstrating that public compute could train a frontier-scale model.
