As Generative AI (Gen AI) technologies mature, the challenge of making these systems predictable remains a focal point for developers. Gen AI models, such as OpenAI's GPT series, create content by generating one token at a time based on probability. While this probabilistic nature is powerful, it can lead to unpredictable outcomes, manifesting in issues like hallucinations, biases, and randomness. In this post, we’ll dive into technical strategies for enhancing predictability in Gen AI, covering everything from adjusting temperature settings to incorporating human oversight.
Why Predictability Matters in Gen AI
The term "predictability" in Gen AI refers to a model's ability to produce reliable and consistent outputs that align with user expectations. Predictable AI is especially important for applications in sensitive sectors such as finance, healthcare, and law, where reliability is paramount, and mistakes can have serious consequences.
- Hallucinations: When Gen AI outputs inaccurate or fabricated information, this is known as a hallucination. These are particularly problematic in systems where factual accuracy is essential.
- Bias: Gen AI systems inherit biases present in their training data. If the data reflects societal biases, the model may produce biased outputs, reducing reliability in diverse applications.
- Randomness: Due to their probabilistic nature, Gen AI systems often display randomness in responses, making it difficult to guarantee consistency across multiple interactions.
To build AI systems that are both powerful and predictable, developers need to incorporate specific techniques that align the AI's behavior with user expectations.
Adjusting Temperature Settings
The "temperature" setting in Gen AI models controls the degree of randomness in their outputs. When the temperature is set to a higher value (e.g., 1.0), the model generates more creative, varied responses. Lowering the temperature to 0, however, reduces randomness and pushes the model to choose the most likely token in each generation step.
For instance, a chatbot designed for customer support might benefit from a low-temperature setting to maintain consistency and prevent "creative" answers that might confuse users. On the other hand, a creative writing assistant could benefit from a higher temperature to encourage varied output.
Setting the temperature close to 0 in your code ensures the model generates factual, reliable content, ideal for applications requiring predictable results.
Processing Prompts for Control and Clarity
Processing prompts is the practice of modifying or structuring input prompts to influence the model's responses. This technique helps guide the AI toward specific behaviors and outcomes, reducing unwanted responses and ensuring consistent performance.
- System Instructions: Many AI APIs support system instructions, where you can include directives that set the context or behavioral guidelines for the AI. For instance, setting an instruction like "Provide only factual answers and avoid conjecture" can help reduce instances of hallucinations in knowledge-based applications.
- Few-Shot Learning: Few-shot learning involves providing the model with several examples within the prompt to demonstrate desired response patterns. Unlike zero-shot learning, where no examples are given, few-shot learning sets clear expectations for the format and tone of responses. Example with Few-Shot Learning: If you’re building a Q&A engine, you can start with a few prompt-completion examples to "teach" the model how to respond to questions in a standardized way.
prompt = """
Q: What is AI?
A: AI stands for Artificial Intelligence. It is the simulation of human intelligence in machines.
Q: What is machine learning?
A: Machine learning is a branch of AI focused on training machines to learn from data without explicit programming.
Q: How does neural network work?
A:
"""
By adding three to four Q&A examples and ending with an open question, the model recognizes the pattern and continues to respond consistently.
⚠️ Drawback: Processed prompts can increase input length, potentially hitting token limits and reducing coherence if they diverge too much from the user's original intent.
Keeping Humans in the Loop
Keeping humans in the loop means involving human oversight in Gen AI outputs to monitor and correct inaccuracies. This can enhance model performance, accountability, and trust.
Designing for Human Oversight
Building interfaces that allow users to review, accept, or reject AI-generated content can prevent unchecked errors. For example, adding "like/dislike" buttons or report options gives users control over the AI output. This feedback can then be used to refine the model.
💡Implementation Tip: For applications where accuracy is critical, consider adding validation steps. If a generative system is used in customer support, allow users to rate responses or flag issues. Implementing a feedback loop can directly improve system quality.
Gathering User Feedback Through Dogfooding and Design Partnerships
User feedback allows developers to continuously improve AI performance by observing real-world use cases. "Dogfooding" refers to the practice of using one's product as a user, while strategic design partnerships involve working with early adopters to get rapid feedback.
If you’re developing a Gen AI for document summarization, encourage users to rate the accuracy of summaries. If 10% of users report inaccuracies, you can identify specific areas needing improvement. Feedback loops are instrumental in surfacing model weaknesses early, especially when combined with structured data collection and user consent.
Transparency and Ethics: The Foundation of Predictable AI
Transparency involves openly communicating the limitations and risks of using Gen AI systems to users, especially in sensitive industries like healthcare or finance. Ethical deployment includes getting user consent for data collection and ensuring data privacy and security.
You should prioritize user data privacy for ethical considerations, and collect feedback data only with full consent. Communicate how data will be used and the security measures in place to protect it.
💡Implementation Tip: You can inform users about possible biases and hallucinations through in-app notifications or onboarding tutorials.
