Key Insights

• •

  Most AI applications no longer require building foundation models from scratch; the focus is now on application development and integration.

• •

  Single, all-purpose chatbots (everything chatbots) are insufficient because they handle high ambiguity and diverse, often complex tasks poorly.

• •

  Sarah introduces the ambiguity footprint as a framework to measure AI application complexity and risks across several axes such as task complexity, context, interface, prompt openness, and sensitivity.

• •

  AI features that support simple, complimentary user tasks, rather than critical or complex ones, are easier and safer to build and scale.

• •

  Visible AI interfaces, like chatbots, set clearer user expectations but introduce more ambiguity and management overhead compared to invisible AI (e.g., keyboard optimizations).

• •

  Prompt engineering plays a crucial role in defining the boundaries of AI output, from very open-ended to highly restricted scopes.

• •

  Retrieval Augmented Generation (RAG) helps manage up-to-date context by dynamically querying relevant data chunks rather than using static corpus.

• •

  Evaluating AI outputs rigorously is essential but often underprioritized; without clear quality metrics, teams end up relying on subjective or anecdotal assessments.

• •

  Data ethics and distributed AI implementations can create blind spots, limiting feedback loops necessary for continuous AI model improvement.

• •

  Incrementally building AI applications with smaller ambiguity footprints helps organizations develop expertise and controls before tackling more complex, open-ended AI products.
