Choose a model for a workflow, then verify what answered
A short procedure for the two decisions that sit behind most model trouble: which model name your workflow calls, and whether the thing that answered is the thing you tested. It uses the settings the providers document - auto-selection tiers, follow-the-family aliases, gateway pricing and effort caps - and points to the two narrower guides that go deeper.
For Anyone wiring a model into a repeatable task: a scheduled job, an agent, a document pipeline or a small internal tool where you need to know what ran and what it cost.
Check what a latest model alias points to before you ship
OpenRouter's catalogue lists entries that always follow the newest model in a family. This guide shows how to see what such an entry points to today, and when to call a fixed version name instead.
For Anyone whose script, app or agent calls a hosted model by name and needs to know which model actually answered.
Set a Copilot auto-model tier, then check which model answered
GitHub Copilot's automatic model selection now has three tiers. This guide covers what each tier prioritises, where the setting applies, how usage is charged, and how to see which model produced a response.
For Copilot users who let the tool choose the model and want a lever on cost, quality or speed.
