LLM’s are models.

They have key roles and these roles play an important role in determining the outputs and the efficiency of use for large language models. There are real resource consequences to being cavalier about these things.

An illustration.

The class plan:

  1. Models and inputs: the roles.
  2. The system role and personas.
  3. Local LLMs and details of implementation; we do not really have access to these in commercial products.

LO: Understand the role of system in providing context for an LLM

Ethics: What are the risks of simulating living persons? Deepfakes, etc. but perhaps less excessive.
