Open AI research for everyone — datasets, models and tools, free for all
Re-LAION-5B offers about 5.5 billion image–text link pairs, and LAION-BVD adds a 10-million-hour open video corpus for vision-language, audio-language and video research.
Scalable, openly licensed implementations plus pretrained weights for contrastive language–image training, so teams can reproduce or fine-tune CLIP-style models themselves.
Training code, evaluation utilities, papers and documentation are released alongside results, letting researchers compare datasets and checkpoints on equal footing.
Open-sci-ref publishes open baselines and intermediate checkpoints for comparing training datasets and language-model quality.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
