How to choose
The right course depends on where you are now and what you want to do next. Find yourself in one of the three groups below.
You are new to AI and want to understand it. Start with the courses that assume no technical background and focus on ideas over code.
- Elements of AI, if you want to understand how AI actually works
- Google AI Essentials, if you want practical use for daily work
- OpenAI Academy or Anthropic Learn, if you already use a chatbot daily and want to use it better
You work in a specific company or tool. Pick the course that matches your environment so the skills apply directly to your job.
- Microsoft AI Fundamentals, for teams on Microsoft or Azure
- IBM SkillsBuild, for managers who want the business side of AI
- Salesforce Trailhead, for people in sales and marketing
You want to build things yourself. Move to the technical courses once the basics feel comfortable.
- Prompt Engineering for Developers, a short bridge into building simple tools (basic Python helps)
- Hugging Face, the deepest option, covering language models, agents, image, audio and vision
Pick one, finish it, then decide if you want the next. You do not need all nine.
