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.
Build, train, and deploy computer vision for the physical world
Label thousands of images in minutes using frontier models and custom filters, then curate datasets for training.
Combine detection, tracking, and logic blocks to orchestrate actions, update databases, and connect to industrial systems.
Run high-speed inference in the cloud or on edge devices, processing live video and images wherever the application lives.
Get into production quickly with an agent that sees the world, understands what is happening, and triggers actions.
