ZDNET roundup: free AI courses and certificates to upskill

ZDNET published a roundup of free online AI courses and certificates and says the writer tested at least one class from each provider. The guide highlights options for building generative AI and machine learning skills without paying for expensive programs. Providers covered include LinkedIn Learning (more than 1,500 AI courses, subscription model), Harvard's CS50 (free to take with an optional paid verified certificate), Microsoft Skills Fest (a free training event that earned a Guinness World Record in April and May 2025), Amazon/AWS (courses on prompt engineering and Bedrock), IBM SkillsBuild (an AI Fundamentals credential of six courses and an AI Ethics module), DeepLearning.AI (ChatGPT and LLM-focused training), the OpenSSF/Linux Foundation (writing secure code with AI), Udemy (trial and subscription options), and Grow with Google (a free two-hour Generative AI for Educators course developed with MIT).

The guide notes course styles and depth vary and recommends checking employer or school access for free memberships. It also cautions that micro-degrees differ from accredited degrees but says certificates can still be a useful résumé item if the cost is reasonable. Many of the courses remain available on demand, though some require registration or a paid option for verified credentials.
