FREE - 2x AI Online Courses (Prompt Engineering & Programming; Building Custom LLMs) @ Columbia University

Assuming you will be actually doing these AI & Data Science courses instead of saving them to your account and never looking at them again, note that the estimated time commitment is 4-5 hours per week for two weeks. The former module (prompt engineering) is also rated as lower perceived effort than the latter (1/4 vs 3/4 - I have no idea what those ratings mean though). Both courses presume basic Python programming knowledge. The former operates within Google Colab using Open AI and DeepSeek APIs. Happy learning!
