AI engineering courses, certificates, and the world's biggest AI newsletter
A broad catalog covering machine learning, deep learning, transformers, generative AI, prompting, and agentic AI, with tracks for data/ML practitioners, software developers, and complete beginners.
Industry-recognized certificates and specializations designed to signal job-ready skills, supported by coding labs and portfolio projects you can show in interviews.
A free weekly newsletter written by technical experts that summarizes the most important AI news, research, and analysis for developers and practitioners.
Pro members get interactive labs and practice quizzes so they can apply each concept immediately rather than only watching lectures.
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.
