Definition
What it is
A model is the trained AI system that does the work: writing, summarizing, classifying, generating images. Large language models (LLMs) handle text; other models make images, video, or speech.
Models differ in quality, speed, and cost. A big model writes better but is slower and pricier; a small one is fast and cheap for simple jobs like sorting emails into categories.
You can ask your coding agent to use a specific model, or describe the trade-off ("fast and cheap" or "highest quality").

How to ask for it
Vague
“Use AI for this.”
Why it works
"Use AI" hides the speed/cost/quality choice; naming which model tier fits each job is a real decision.
