Libertadia puts 400+ models in the same chat. The usual mistake is leaving the strongest one on all day: balance disappears on summaries and emails a cheap model would handle just as well.
Start from the task, not the brand
Classify, draft, and search with light models. Keep the advanced ones for reasoning, reviewing a contract, or designing an agent. The chat picker exists so you can switch mid-conversation without opening another tab.
If the team shares a balance, agree on two or three models per kind of work. Nobody improvises, and spend stays visible.
