The Google Prompting Essentials course on Coursera is structured into four distinct modules designed to take you from a novice to a pro. The first module, “Start writing prompts like a pro,” introduces foundational frameworks for crafting effective prompts. The second, “Design prompts for everyday work tasks,” provides practical applications for things like emailing, brainstorming, and summarizing documents. Module three, “Speed up data analysis and presentation building,” focuses on using AI for more specific, data-heavy tasks. Finally, the fourth module, “Use AI as a creative or expert partner,” dives into advanced techniques like prompt chaining and creating AI agents.

Module 1: Mastering the Fundamentals of Prompting

[0:59.397]

Before diving deep, it’s crucial to understand what prompting really is. At its core, it’s about giving clear instructions to a generative AI to get a desired result.

Prompting is the process of providing specific instructions to a gen AI tool to receive new information or to achieve a desired outcome on a task.

This process isn’t limited to just text; it can involve images, videos, sound, and even code.

[1:13.297]

The course introduces a powerful 5-step framework for designing any prompt: Task, Context, References, Evaluate, and Iterate. This structure is the backbone of effective prompt engineering. The Task is simply what you want the AI to do. For instance, if you’re looking for a birthday gift for a friend who loves anime, your initial task might be:

suggest a gift related to anime for my friend's birthday.

[1:27.797]

While this prompt works, the results can be generic. To elevate your prompt, you need to incorporate a Persona (the role you want the AI to adopt) and specify the Format of the output. By refining the task, you can get a much more specific and useful response. For example, assigning a persona transforms the prompt:

Act as an anime expert to suggest an anime gift for my friend's birthday.

This simple addition tells the AI to access a deeper level of specialized knowledge, resulting in more detailed and categorized suggestions. You can further refine the output by asking the AI to organize the information into a table for clarity.

[2:01.597]

The second step, Context, is about providing the necessary background information. The more relevant context you give the AI, the more tailored and accurate its response will be. Continuing with our gift example, you can add personal details:

Act as an anime expert to suggest a gift related to anime for my friend's birthday and she is turning 29 years old. Her favourite animes are Shangri-la Frontier, Solo Leveling, and Naruto.

[2:17.657]

By providing this context, the AI can generate highly specific gift ideas tailored to your friend’s exact interests, moving from generic “anime merchandise” to “Shangri-La Frontier Merch” or “Naruto Treasures.”

[2:20.657]

Third, providing References or examples of what you’re looking for can significantly improve the AI’s output. Sometimes it’s easier to show than to tell. You could mention past gifts your friend enjoyed, like a specific piece of jewelry, to guide the AI toward similar suggestions.

[2:44.887]

The final two steps are Evaluate and Iterate. After you receive a response, you evaluate if it meets your needs. If not, you iterate on your prompt by refining the task, adding more context, or providing better references. Prompting is a circular process. The key is to keep refining until you achieve the desired outcome. Remember the course’s mnemonic: ABI (Always Be Iterating).

[3:26.967]

To help remember this framework, you can use the mnemonic: Tiny Crabs Ride Enormous Iguanas (Task, Context, References, Evaluate, Iterate).

Fine-Tuning Your Prompts: Iteration Methods

[3:48.402]

Sometimes, your initial prompt and the 5-step framework only get you 80% of the way. To close the gap, the course introduces four iteration methods:

1. Revisit the prompting framework: Add more detail to any of the five steps.
2. Separate prompts into shorter sentences: Instead of one long, complex command, break your request into smaller, sequential tasks. This helps the AI process each step more effectively.
3. Try different phrasing or switch to an analogous task: If asking for a “marketing plan” yields bland results, try asking for a “compelling story” about how a product fits into a customer’s life. This re-framing can unlock more creative outputs.
4. Introduce constraints: Limit the AI’s options to narrow its focus. Instead of asking for a “road trip playlist,” ask for a playlist featuring only “Brazilian music with a chilled, adventurous tempo about heartbreak.” Constraints often lead to more interesting and specific results.

[5:48.883]

A helpful mnemonic for these methods is: Ramen Saves Tragic Idiots (Revisit, Separate, Try different phrasing, Introduce constraints).

Expanding Beyond Text: Multimodal Prompting

[5:53.073]

Modern AI, like Google’s Gemini, isn’t just about text. Multimodal prompting involves using different types of media—like images, audio, or video—as part of your input. This allows for more dynamic and context-rich interactions. For example, you can upload an image of your nail art and ask the AI to write a social media post about it, or upload a photo of your fridge’s contents and ask for recipe suggestions.

Navigating AI’s Limitations

[7:12.513]

It’s important to be aware of two major issues when using generative AI tools:

1. Hallucinations: This occurs when an AI provides outputs that are inconsistent, incorrect, or nonsensical. A famous example is an AI incorrectly stating the number of “R"s in the word “strawberry.”
2. Biases: Since AI models are trained on vast amounts of human-generated content, they can inadvertently inherit human biases related to gender, race, and other sensitive topics.

To mitigate these issues, always adopt a “human in the loop” approach. It is your responsibility to review, fact-check, and validate all AI-generated content before using it.

[7:50.403]

Here’s a quick checklist for using AI responsibly:

1. Evaluate Suitability: Ensure the AI is right for the task and doesn’t reinforce harmful biases.
2. Get Approval: Obtain consent from your company before using AI on projects.
3. Protect Privacy: Use secure tools and avoid exposing sensitive data.
4. Validate Outputs: Review all AI-generated content before sharing.
5. Be Transparent: Disclose your use of AI to teams and clients.

Module 4: Advanced Techniques and AI Agents

This module is where the course truly shines, introducing advanced concepts that can dramatically enhance your productivity.

Advanced Prompting Techniques

[12:31.253]

• Prompt Chaining: This technique involves guiding the AI through a series of interconnected prompts, where the output of one prompt becomes the input for the next. This allows you to build complex outputs step-by-step, adding new layers of complexity along the way. For example, you can first generate a summary of a novel, then use that summary to create a tagline, and finally use both to build a promotional plan.

[14:05.423]

• Chain of Thought (CoT) Prompting: This simply means asking the AI to “explain its reasoning” or “show its work” step by step. This helps you understand the AI’s logical process and allows you to correct its course if it starts to go wrong, leading to more accurate results.

• Tree of Thought (ToT) Prompting: An even more advanced method, ToT allows the AI to explore multiple reasoning paths or “branches” simultaneously. This is ideal for complex, abstract problems where multiple solutions might exist, such as brainstorming different creative concepts or developing novel plotlines.

Creating and Using AI Agents

[16:04.493]

The final section of the course covers AI Agents—specialized AI experts designed to help with specific tasks. You can create agents for anything from coding and marketing to providing personal feedback. The course provides a simple five-step framework for creating your own agent:

1. Persona: Define the agent’s role (e.g., “a successful personal fitness trainer”).
2. Context and Scenario Details: Explain the situation and your goal (e.g., “I’m looking to improve my overall fitness”).
3. Conversation Type: Specify how you want the interaction to proceed (e.g., “Ask me about my workout routines and give me feedback”).
4. Stop Phrase: Create a command to end the simulation (e.g., “When I want the conversation to end, I’ll write, ’no pain, no gain’”).
5. Requested Takeaways: Define what you want the agent to provide at the end (e.g., “Provide a summary of the advice you provided”).

[16:50.533]

By clearly defining these five elements, you can create powerful, customized AI agents like Agent Sim for role-playing scenarios or Agent X for getting expert feedback on any topic you choose.
