Six Key Principles for Designing Generative AI Applications

1. Design Responsibly

At the core of any AI application is the principle of responsible design. For Generative AI, this means ensuring that the system addresses real user needs while minimizing potential harms such as bias or misuse. A human-centered approach is critical. In the mental health domain, for example, this principle involves designing content that aligns with best practices in therapy and mental health care, while also safeguarding user privacy and safety.

Actionable Strategy:

• Identify and resolve value tensions: Consider the needs of all stakeholders—users, developers, and organizations—and find a balance to avoid harmful outcomes.

2. Design for Generative Variability

Generative AI systems often produce multiple distinct outputs from the same input. This variability is both a strength and a challenge. For Generative AI Solution Architects, it is crucial to provide users with ways to manage and interpret these outputs. For instance, in a mental health application, offering users several options for coping strategies based on a single input (e.g., stress management) can help them choose the most suitable one.

Actionable Strategy:

• Leverage multiple outputs: Display several options and highlight their differences to guide users in making informed choices.

3. Design for Mental Models

Understanding the user’s mental model—how they perceive and interact with the system—is key to designing intuitive Generative AI applications. Many users may not be familiar with how Generative AI systems generate content, so providing educational tools and contextual explanations can help bridge the gap. For example, a mental health app might explain why certain suggestions are made and how users can get the most personalized results.

Actionable Strategy:

• Teach effective use: Include interactive tutorials and examples to help users understand the system’s behavior and outputs.

4. Design for Co-Creation

Generative AI excels when users collaborate with the system to refine outputs. This principle is particularly useful in applications where users need to tweak and customize generated content. In a mental health app, for instance, users could modify the tone or structure of a meditation exercise to better fit their emotional state. Co-creation ensures that the system becomes a partner in delivering personalized solutions.

Actionable Strategy:

• Support co-editing of outputs: Allow users to adjust Generative AI-generated content to better meet their needs, ensuring a more engaging and personalized experience.

5. Design for Appropriate Trust and Reliance

Trust is a critical factor in AI systems. Users need to know when they can rely on the AI’s outputs and when they should be skeptical. In high-stakes fields like mental health, trust calibration is essential to prevent over-reliance on AI-generated advice. By transparently communicating the AI’s limitations, users can better judge when to accept or question its recommendations.

Actionable Strategy:

• Calibrate trust with explanations: Provide clear explanations of how the AI generates its outputs, including its limitations, biases, and uncertainty.

6. Design for Imperfection

Generative AI systems are not perfect and may produce outputs that are inaccurate or misaligned with user expectations. Architects must create systems that not only highlight these imperfections but also offer ways for users to correct or improve the AI’s suggestions. In mental health management, where precision is vital, ensuring that users can easily request adjustments or alternative content is critical.

Actionable Strategy:

• Offer ways to improve outputs: Include mechanisms for users to provide feedback, regenerate content, or tweak results to better align with their goals.

Developing Generative AI Systems Design through Iteration

An iterative approach is fundamental to building Generative AI applications that are both adaptable and user-centered. Iteration ensures that user feedback is continuously incorporated into the design process, leading to systems that evolve based on real-world interactions and user needs.

This iterative approach is motivated by the following desiderata:

• To provide Generative AI System Designers with language to discuss UX issues unique to generative AI applications.
• To Provide Generative AI System Designers with concrete strategies and examples that are useful for making difficult design decisions, such as those that involve trade-offs between model capabilities and user needs, motivated by work that focuses simultaneously on end-users of systems and on designers as strategic and collaborative end-users of guidelines.
• To sensitize designers to the possible risks of Generative AI applications and their potential to cause a variety of harms (inadvertent or intentional), and outline processes that could be used to avoid or mitigate those harm.

Step-by-Step Iterative Systems Design

1. Initial Prototyping: Develop a basic prototype focusing on key user needs and aligning with the six principles. In the case of a mental health app, this could involve generating basic relaxation exercises.
2. User Testing and Feedback: Deploy the prototype to a small group of users and gather feedback on usability, effectiveness, and personalization. Professionals and end-users could provide insights on the suitability of the AI-generated therapeutic content.
3. Refinement: Refine the system based on the feedback, improving areas where the generative content was too generic or didn’t meet user expectations. For instance, refine the AI to deliver more personalized mental health strategies.
4. Repeat and Scale: Continue iterating with new features, expanding user testing, and incorporating additional user preferences. As the system learns, it becomes more effective at generating varied and accurate outputs tailored to individual needs.

I believe the six design principles for Generative AI applications along with the iterative approach are valuable and critically important for several reasons:
