Human review for automation with a prompt

  • Article

This article emphasizes the critical role of human review in deploying the Create text with GPT feature in Power Automate. This feature utilizes the text generation model from AI Builder, powered by Azure OpenAI Service. Although these models are highly effective, they can sometimes generate misleading or fabricated information and are susceptible to prompt injection attacks.

Important

Prompt injection attacks

A prompt injection attack occurs when a third-party takes advantage of the model's inherent trust in all input sources. The attacker injects a prompt into content that a legitimate user asks the AI solution to interact with, leading to a change in the AI solution's output, and potentially, its actions.

For instance, consider a scenario where a citizen developer uses the Create text with GPT action to formulate responses to customer complaints collected from various platforms such as emails, social media, or forums. An attacker could insert a prompt into the content from one of these sources. This scenario could deceive the model into generating a response that differs from the intended one. The response could be inappropriate, incorrect, or harmful. Incorrect information being dispatched to customers might negatively affect the company's reputation and customer relationships.

Fabrication in AI models

Fabrication, also known as hallucination, is another challenge faced by AI models, including the text generation model. Fabrication occurs when the AI model generates information that isn't based on provided inputs or pre-existing data, essentially inventing or hallucinating information.

For instance, if the AI model is asked to generate a summary of a historical event based on a given text, it might include details or events that weren't mentioned in the source text. For example, a flow creates a synopsis of a meeting based on the transcript of the recording. The input data includes details about the attendees, the articles discussed, and the decisions made. However, the model might generate a summary that includes an action item or a decision that was never discussed in the meeting. This situation is an instance of fabrication, where the model has hallucinated information that doesn't exist in the input data.

To mitigate the risk of fabrication, it's crucial to implement responsible AI practices. This includes rigorous testing of the prompt and the flow, providing the model with as much grounding information as possible and finally implementing a robust system for human oversight.

Address risks through responsible AI practices

We advocate for responsible AI practices as a means to reduce risks. Despite having strategies in place to moderate the content produced by the model, managing the model's propensity to generate fabricated responses or succumb to prompt injection attacks remains a complex challenge. We acknowledge these risks and reaffirm our commitment to human oversight and control.

In recognition of the necessity for seamless automation, we're proactively enhancing our safety systems and seeking a deeper understanding of these challenges. Our objective is to further refine the text generation model with appropriate safety measures, in line with our principles of responsible AI by design, returning control to developers wherever feasible.
