1. If an error was recorded in a previous chat
Carat AI may not immediately know your real-time usage information. If you continue requesting in a chat where generation previously failed due to insufficient usage, the AI may remember the error and repeat the same message. In this case, try saying “I’ve recharged my usage, please generate again. (your request)” or open a new chat and request again.2. If the required usage is more than your remaining usage
This is the most common cause. Even if you have some usage, generation is not possible if the cost of one request for the feature (e.g., advanced video model) exceeds your remaining amount. Advanced models like Google Veo (Veo 3), Sora 2, and lip sync consume a lot of usage. This applies not only to free users but also to subscribers if their remaining usage is less than what the feature requires. In this case, try using a more economical basic generation model, or consider [subscribing/upgrading your plan] or [recharging usage].3. If you’re low on usage
You may not be able to generate further within your daily free usage. To keep using Carat right away, head to the upgrade page and use credit top-up or upgrade to a subscription plan. Top-ups have no limit on the number of times and let you add credits whenever you need them. You can check your remaining usage and the next recharge time at the following locations:- App: Bottom [Profile(프로필)] → Top right [Menu(메뉴)] (☰) → [My Credits(내 크레딧)]
- Website: Bottom left [Account nickname(계정 닉네임)] → [Settings(설정)] → [My Credits(내 크레딧)]
