Our take

Based on the ratings of 6,352 students, a sample of their written reviews and the syllabus, as the course stood in February 2024. No course pays to be reviewed.

This is a beginner-friendly tour of Google's Gemini models, taught by Colt Steele across 102 lectures and roughly 8.7 hours. It covers Gemini Pro and Ultra, prompt engineering, Google AI Studio, Gemini Vision, and model parameters like temperature and top-p, then moves into building apps with the Python and Node SDKs and a section on Vertex AI. No coding background is required except for those two SDK sections.

Reviewers consistently praise how clearly Colt explains the concepts, and one reviewer calls the segment lengths and pacing a good fit for beginners. The complaints cluster around one thing: Gemini and its tools change fast, and the Google AI Studio interface shown in the videos has already shifted, which frustrates viewers working through the structured-prompt and test-input lectures. One reviewer also found the material too basic and wanted more advanced topics to show up.

The course was last updated in February 2024, and that gap shows in the reviews, several from 2025 and 2026 flag it as dated even while still finding the fundamentals useful. At 4.6 stars across more than 6,300 ratings, it holds up as a solid entry point rather than a reference for Gemini's current interface. Treat it as a foundation for how Gemini and prompt engineering work, and expect to double-check the newest screens and features on Google's own docs.

Best forNon-developers and coders who want a guided tour of Gemini's tools, prompting, and both Python and Node SDKs.
Skip it ifYou already use Gemini daily and want advanced techniques rather than a beginner walkthrough.

Pros

  • Colt Steele's explanations get called out repeatedly as clear and easy to follow
  • Covers both the Python and Node SDKs plus Vertex AI, not just the chat interface
  • Segment lengths suit beginners, one reviewer notes
  • Includes Gemini Vision Pro for image and video prompting

Cons

  • Filmed in early 2024, and Google AI Studio's interface has since changed in ways that trip up the prompt-studio lectures
  • One reviewer found the content too basic and wanted deeper, more advanced material
  • Runs close to a full working day for some viewers, who called it long
Good course, however the UI of Google AI Studio has been updated so quit a lot of the tutorials on for example structured prompts and test inputs are now outdated.
Elien Vissers-Similon, a student

Built for true beginners and non-developers; the Python and Node SDK sections need existing coding experience to follow.

Instructor Details

Colt Steele

Hi! I'm Colt. I'm a developer with a serious love for teaching. I've spent the last few years teaching people to program at 2 different immersive bootcamps where I've helped hundreds of people become web developers and change their lives. My graduates work at companies like Google, Salesforce, and Square.

Most recently, I led Galvanize's SF's 6 month immersive program as Lead Instructor and Curriculum Director. After graduating from my class, 94% of my students went on to receive full-time developer roles. I also worked at Udacity as a Senior Course Developer on the web development team where I got to reach thousands of students daily.

I’ve since focused my time on bringing my classroom teaching experience to an online environment. In 2016 I launched my Web Developer Bootcamp course, which has since gone on to become one of the best selling and top rated courses on Udemy. I was also voted Udemy’s Best New Instructor of 2016.

I've spent years figuring out the "formula" to teaching technical skills in a classroom environment, and I'm really excited to finally share my expertise with you. I can confidently say that my online courses are without a doubt the most comprehensive ones on the market.

Join me on this crazy adventure!

Learnt a lot about gemini and how to use it effectively and I hope to put this knowledge to use for my work.

By Anonymized User on 1/8/2026

I am not sure yet. Gemini always irritates me when it pops up on my phone. I figured I would try to learn about so it might not annoy me so much.

By Pranab. D. Jadhav on 1/6/2026

Yes the course is informative & very much usefull as a basics are clearly explained along with simple examples

By Hadi irianto on 1/6/2026

although it's a long (1 full working day) but quite interesting to learn how AI/gemini work

By Conrad Claycomb on 1/2/2026

It was a good course. I learned a lot about Google Gemini that I have put to use already. The only downside is that the interface for Google Gemini Studio has changed a bit since the videos were created. Other than that, I was very happy with the content.

By Swarnim Shukla on 12/22/2025

It was quite good course, explain key fundamentals of google ai studio and vertex ai, key parameters and way of fine tuning responses.
