Current model
Free browsing may show ads on selected browse, search, and safe concept-page surfaces when ads are explicitly enabled. Supporter removes ads where ads are eligible and adds the convenience features described on the Pricing page.
When advertising is enabled, Open Model Lab uses manually placed Google AdSense units only. The current architecture is manual-first and does not rely on Auto ads as the primary mode.
The intent is simple: ads can support public browsing without interrupting the live science-learning interaction. Before approval and explicit activation, the ad system stays dormant and renders nothing.
