Kaggle

Kaggle is an online platform for data science and machine learning, now presented by its owner Google as an AI proving ground. It brings together competitions, hackathons, reproducible notebooks, datasets, models and learning courses in one community, and it is where many practitioners build a public portfolio by competing against others on defined problems. Three groups use it. AI builders compete, learn and publish work. Organizations host competitions and hackathons to source solutions and talent. Researchers develop and maintain benchmarks, using crowdsourced evaluations and an open source Benchmarks SDK to run custom evaluations of language models and generative AI. Hosted benchmarks include contributions from IBM Research and Google DeepMind, and a grant program offers compute and infrastructure support for new research benchmarks. Hackathons can be public, restricted to invited participants, or fully private for internal teams and classrooms. Competition formats include hackathons judged on project writeups, prediction contests scored automatically against hidden ground truth, and simulation contests where live AI agents play head to head. Registration is by Google account or email. The vendor states the Benchmarks SDK is available at no cost, and hosting a Community competition carries no cost. Featured competitions, where the Kaggle team helps design, promote and run the event, are priced on request, and the site lists their pricing as varying.
