Publish
A change reaches visitors when you publish your agent. Until then they keep the model they had.
What stays the same with any model
Only your content
Every model answers only from the pages, documents and written answers you approved, with the sources under every answer.
Checked before it is shown
Numbers, dates, links and product names in a reply are checked against the quoted excerpts. If one is not there, the visitor sees the excerpts instead.
One answer counts as one
Your monthly allowance is the same with every model. There are no credits per model and no surcharge.
No data kept by the model
Every model is reached through OpenRouter on routes that keep no data, with data collection switched off.
A $0.008 ceiling per answer
A model whose list price passes that line leaves the list until it is back under it. Answers then continue with the next model, and Settings tells you.
Some replies use no model
Exact matches to your written Q&A are answered without a model, and so are some questions your content clearly does not cover.
