2.6 Choosing and Evaluating Generative AI Models

When selecting a generative AI model, several factors need to be considered:

  • Model type
  • Performance
  • Capabilities
  • Constraints
  • Compliance

Types of Generative AI Models

Generative AI foundation models (FMs) are trained on large datasets and can generate various types of content such as text, images, code, and more. Common models include:

  • Variational Autoencoders (VAEs)
  • Generative Adversarial Networks (GANs)
  • Autoregressive models

These models are adapted to specific domains, like language understanding or image generation, and can produce high-quality outputs for their respective tasks.

Some well-known FMs include:

  • Stable Diffusion (for image generation)
  • GPT-4 (for natural language processing)

Business Metrics for Generative AI Models

When assessing the success of generative AI models, track these business metrics:

  • Accuracy
  • Conversion rate
  • Customer lifetime value (CLTV)
  • Efficiency

These metrics help measure performance, quality, and impact, and they are important for monitoring and improving AI models over time.

Challenges with Foundation Models (FMs)

To integrate generative AI into business systems like CRM or ERP, organizations need:

  • Skilled technical staff
  • Sufficient computational resources
  • Well-maintained models

FMs can deliver valuable insights but require the right infrastructure to work effectively and meet business needs.

Key Output Quality Metrics

To ensure high-quality AI outputs, businesses should track the following:

  • Relevance
  • Accuracy
  • Coherence
  • Appropriateness

These are critical in customer-facing applications like chatbots, where user satisfaction is directly impacted by the quality of AI responses.

Operational Efficiency

Businesses should measure operational efficiencies such as:

  • Task completion rates
  • Error rates (lower errors = higher accuracy)

Evaluating return on investment (ROI) is crucial for understanding the benefits of FMs and ensuring that the costs align with the outcomes.

Final Tip: Always regularly measure, monitor, and reassess your model to ensure it meets evolving business goals.
