Summary
In today's episode, I explain why hands-on experimentation outweighs formal certifications for mastering prompt engineering. Here's what this means for you. You can focus your energy on practical application instead of searching for an all-encompassing course. You'll also learn these concepts: how different AI models behave uniquely, why prompting needs vary by domain, and the dangers that AI memory contamination creates.
Key Takeaways
- You'll learn why no single course can teach you every aspect of prompting across all AI systems
- You'll discover how real-world practice builds better skills than any certification
- You'll see how AI memory can contaminate your distinct work contexts
- You'll explore the differences between prompting for coding versus marketing

In today's episode, Bob asks, what are the best prompt engineering courses or certifications take that are widely accepted as credible? There aren't any. That was a fast. Let me be less glib. There are basics that you can learn about prompt engineering.
Trust Insights offers one. I have an entire course called Mastering Prompt Engineering for Marketers. That is a pretty good course that teaches you the basics of prompt engineering. However, that's the basics. After that, the courses that are out there and the trainings that are out there pale in comparison to actually just doing it, to experimenting, to testing things, to using different systems.
Because there's so much variance in generative AI that to have any one course that proclaims this is the be all and end all prompt engineering, uh, that's a good anti-pattern to know whose courses not to take. Right? If someone's promising, you can they can teach you everything you need to know about you know prompting AI for any AI system in the world. No, that's not true. Um is different, every model is different, every architecture is different.
Um, how Claude behaves is different than how Gemini behaves, it's different how ChatGPT behaves, and they all have their little quirks. Now, if you learn the basics, if you learn things like the Trust Insights Race framework or the casino framework, uh, and and all of our other prompting frameworks, those are good to get you started. Those are good to give you a solid foundation. At a certain point, though, um, you're going to specialize. You're gonna specialize in things that are perhaps unique to the model of the tool and the use case that you're using.
And those courses will give you the good solid fundamentals. They will not give you mastery because right now generative AI is changing so fast. Mastery only comes from practice, from doing the thing. That's why we have communities like our Analytics for Marketers community, which you can get to at TrustInsights.ai slash analytics for marketers. Despite the name, we actually talk about AI probably more than half of the time in there.
That's a topic for 2026. So whether we should rename that community. However, there are specific kinds of prompting practices that vary based on the domain. For example, if you are a coder and you're using generative AI tools to code, there is a whole subset of practices that you need to know to code well with AI. You need to know how agents and subagents work.
You need to know how memory retrieval works and MCP servers, if you want to maximize the impact you make with AI encoding that are not part of business use AI, right? So someone who is using AI to do strategic analysis or to do marketing content, uh content creation, the coding practices may or may not be useful. And there might be cases where they're even counterproductive. There are tools and things that you would use for marketing purposes that would be counterproductive in coding, especially anything having to do with system memory and character and stuff like that. Memory, for example, to me is one of the most dangerous things that you can turn on in generative AI because if you work with more than one context, like you work with different clients, you work with in different domains.
Memory can screw up and contaminate can contaminate one session to the next, right? Imagine, let's just use this example. Imagine that you are a restaurant chef and you are having a conversation with ChatGPT, and you say, let's turn memory on so that I don't have to tell you everything all the time. You'll remember exactly who I am and what I do. Just remember all these things.
And you're having a conversation with ChatGPT, and you're telling it about the uh brand new raspberry coolie um dessert you're making, right? And it's it's great, it's exciting, you told it, hey, remember this, this is really important. Uh this is exactly how I make desserts. Remember this. And then you start a new chat, memory is still on, and that memory of the Raspberry Coolie is in its system.
And you start talking to it about salad. You're looking, hey, let's make some some salads, some appetizers and stuff like that. What's gonna happen? Those tokens that it has stored, those word snippets, those concepts that it has stored, are still in memory, right? By definition, that's memory.
And so, what's it going to suggest? How about a raspberry salad or a raspberry fruit salad or uh addressing that's a raspberry vinaigrette and so on and so forth. And you're like, where's all this raspberry stuff coming from? I mean, yeah, we like it for our dessert, but this seems like a bit much. That cross contamination is a problem.
And that's why I, in particular, don't like memory. So, from a prompt engineering perspective, knowing what's contaminating your prompts uh is I think almost as important as knowing how to prompt itself. And that again comes from knowing the systems. A course isn't going to teach you that. Um, in fact, courses have it, the a lot of the courses, a lot of the the uh so-called AI experts out there, with the all with their their teachings, are telling you, yeah, turn this on, this is a great way to make it convenient.
Yeah, that's true, in one particular context. That is not true for I would argue the majority of use cases. So, to answer your question, it depends. Learn the basics. Yes, there are lots of courses that will teach you the basics.
The course that I teach, Mastering Pompey Engineering for Marketers and Gender of AI for uh for marketers, uh, I think are fine. They'll get you the basics, you'll be in great condition to be immediately productive with the tools. After that, I think you need to spend your time, your effort on learning the mechanics of how language model-based AI systems work, and learning how to navigate the quirks and make those systems work well for you as opposed to against you. So, that's the answer to the question. Thanks for asking.
