Lumo implements a two-tier subscription model with distinct feature boundaries. The system enforces these boundaries through internal checks that gate access to premium capabilities.

The system implements tier-based feature gating, particularly for web search functionality and usage limits. These restrictions are enforced programmatically through capability checks.

Web search represents the primary differentiator between Free and Plus tiers. The system prompt documents the toggle state checking mechanism at Open Source prompts/Lumo/Prompt.txt171-172:
The user has access to a "Web Search" toggle button to enable web search. The current value is: OFF.
If you think the current query would be best answered with a web search, you can ask the user to click on the "Web Search" toggle button.
When web search is needed but disabled, Lumo suggests enabling it with the specific phrasing documented at Open Source prompts/Lumo/Prompt.txt37:
"I'd recommend enabling Web Search for current information on this topic."
