For each AI use, proportionality of the AI system to the task is weighed against documented alternatives.
Tier II
Optional extra depth on top of the baseline. Organizations with more mature AI governance, or more exposure, may choose to adopt these for more thorough control over AI than the baseline alone provides.
Why
Large general-purpose large language models (LLMs) are frequently applied to narrow tasks. Smaller, lesser-known models or non-LLM tools are often faster, cheaper, more accurate and less resource intensive than LLMs on such tasks.
How
For listed AI uses (see RG.2), record which alternatives were assessed, along with a short reasoning on why they were not selected.
