Tiers and the attribution badge
5 min
Your tier controls three things: which models the agent may use, how much sandbox capacity a session gets, and whether your published site carries the Lunax badge.
The badge
Sites on the FREE tier serve a small "Built with Lunax" badge. It is added when the page is served, not when the site is built — so upgrading removes it immediately, with no rebuild, and the agent cannot be asked to delete it from your source to get around it.
If we ever cannot read your tier, we serve the badge. A failed lookup should cost a paid customer a badge they can report, never hand every site a free removal.
Models
FREE sessions run on the free model pool. Paid tiers unlock stronger models and larger context, which matters most on long sessions and large codebases — a bigger model is better at holding an entire project in mind while changing one part of it.
Capacity
Higher tiers get more sandbox CPU and memory, longer sessions, and a larger source upload limit for bring-your-own-code projects. A build has to download, decompress and compile inside a time limit on shared hardware, which is why the limit exists at all.
