A larger model is not always necessary for a focused website assistant or document-navigation task. Smaller open models can run locally and support useful interactions. Their limitations, however, make task design and evaluation especially important. Model size alone does not establish either usefulness or environmental benefit.
Keep the task focused
A narrow knowledge domain is easier to support than an unrestricted assistant. Provide relevant source material and ask for concise answers. Use structured retrieval for exact values such as contact details, instead of asking a model to reproduce them from memory. Keep business availability and other important facts consistent with the authoritative source.
Evaluate the complete experience
Test factual questions, ambiguous wording, missing information, and requests outside the intended scope. Check loading time, memory needs, and behaviour when the model or network is unavailable. A local model still consumes computing resources and requires maintenance. Compare actual workloads before making claims about cost, speed, or energy use.
Make correction easy
Show source links, distinguish directly retrieved facts from generated explanation, and provide a clear handoff to a person. Do not describe a scripted lookup as a language-model response. The best combination may be a small model for explanation, reliable retrieval for exact facts, and a simple interface that helps users verify what matters.
Three things to take away.
- Match model capability to a focused task.
- Retrieve exact values from structured facts.
- Evaluate accuracy, resources, and failure behaviour together.
