This page covers plans, credits, and billing for a personal workspace. Prices, benefits, credits, and billing or refund paths can differ for a team workspace. For team guidance, see Get started with team plans and Manage team billing, seats, and credits.
‘Usage limit exceeded’ can appear when a request needs more credits than you have. The message alone does not establish that your account lacks unlimited benefits or rule out a system issue. When your credits run out, you cannot use an agent conversation. Choosing a model inside a chat still requires separate conversation credits. Unlimited benefits cover generation costs for eligible models and options, not the agent’s conversation costs. If you have enough conversation credits, eligible generation in the agent can still use your unlimited benefit. The generator is the way to keep generating without a conversation when your credits are zero. To generate images or videos with models and options included in your account’s unlimited benefits, open the Generator(생성기). On the web, use [Generator(생성기)] in the left sidebar (open the top-left ☰ on mobile web); in the app, go to [Home(홈)] → top-left menu (☰) → [Generator(생성기)] (app version 2.281.0 or later). The generator uses no conversation credits, but accounts without the benefit and models or options outside its coverage still require credits.

​
Why does this message appear?

The unlimited benefit applies only on accounts that meet the subscription conditions, to specific models (e.g., Nano Banana base, Carat Video), and only when you generate in the Carat app or website. Accounts without an unlimited benefit, including the free plan, pay credits for every feature. Features outside the unlimited benefit consume credits, and when your remaining credits are less than what a feature requires, this notice appears. Background music, sound effects, and advanced video models in particular require a large amount of credits at once, so you may run into this message even while using an unlimited model. The following MCP condition applies only when generating through an external AI tool connected to Carat, not when using the Carat app or website directly. You can also see this notice when you generate through MCP (Carat connected to Claude or another AI tool), because the unlimited benefit doesn’t apply there and credits are deducted even for unlimited-eligible models. See Unlimited benefits don’t apply through MCP for details.

​
To continue conversations or other features that require credits

  1. Top up additional credits: Top up on the upgrade page. (Validity: 1 month from recharge date)
  2. Upgrade to a higher plan: Upgrade to a higher plan with more monthly credits.
  3. Use a lower-cost model: Try the Carat Video (LTX) model, or reduce the video length or resolution and try again.

​
If an eligible generation is still blocked in the generator

If you opened the generator link and selected a model and options covered by your account’s unlimited benefits but generation is still blocked, send support a screenshot of the full screen and the selected model and options. You do not need to repeat information you have already provided. Support can check your account and request history.

​
How to check your remaining credits

  • App: Bottom [Profile(프로필)] → Top right [Menu(메뉴)] (☰) → [My Credits(내 크레딧)]
  • Website: Bottom left [Account nickname(계정 닉네임)] (on mobile web, open the top-left [Menu(메뉴)] (☰) first) → [Settings(설정)] → [My Credits(내 크레딧)]
