Open Data Science (ods.ai) is a community platform for data science, machine learning, and AI practitioners, offering courses, competitions, hubs, and events like Data Fest.
About
Open Data Science, found at ods.ai, is an online community for people who work with or study data science, machine learning, and artificial intelligence. It addresses a common problem in the field: practitioners scattered across companies and cities who need one place to find courses, competitions, talks, and peers with shared interests.
The platform, active since 2015, organizes its content into topic-based tracks, company hubs, and regional community hubs, and it runs seasonal courses such as a Natural Language Processing & LLMs course and a classic machine learning course (OpenMLCourse). Its flagship event, Data Fest, combines online talks with offline days held in cities including Moscow, St. Petersburg, Novosibirsk, Almaty, and Belgrade. Recorded talks from the festival are published as tracks on the site. The site also lists competitions, hackathons, projects, and jobs, making it a hub for both learning and career activity in the Russian-speaking and international data science community.
