All interactions with Carat AI are paid AI services, so usage is deducted even for text-only conversations. Even if you have unlimited image or video generation, conversations with the AI agent are charged separately.

​
Conversation models

The models used for chatting with the Carat AI agent are labeled as follows:
Free plans converse with Carat 2.0 Lite, the most economical model. Subscription plans don’t include Carat 2.0 Lite, so use Carat 2.0 for lighter work and save Carat 2.0 Soul for complex, in-depth requests to keep usage down.

​
Usage deduction rules and types

  • Applies to: All interactions with AI, including general text conversations, Q&A, advice, and information searches.
  • Consumption level: How much is deducted varies widely with the length and complexity of the conversation. The agent doesn’t just reply; it interprets your request and performs reasoning and tasks, so a single request can deduct credits several times over. Agent 2.0 in particular uses more credits for reasoning, tasks, and conversation than Agent 1.0.

​
Unlimited benefits and chat

Unlimited promotions apply only to specific image and video generation models: images such as Nano Banana basic and Z-Image, and for video the Carat Video (LTX) model. Advanced external video models such as Google Veo, Kling, and Seedance are not covered and deduct credits. Conversations with the AI agent use an LLM (large language model), so they are also not covered by unlimited benefits.

​
When credits are exhausted

For free users, once all credits are exhausted, chatting with Carat AI is no longer available. To continue using the service, please upgrade your plan or recharge additional credits. Conversations use credits because the agent reasons through your request before it answers. If your credits run out completely, conversations may become hard to continue, so recharge your credits or upgrade your plan. (If you only need to keep generating unlimited images or videos, use the Generator(생성기). It lets you pick a model and generate without a conversation, so it doesn’t use conversation credits: on the web, open [Generator(생성기)] in the left side panel or go to carat.im/generator; in the app, go to [Home(홈)] → top-left [Menu(메뉴)] (☰) → [Generator(생성기)], on app version 2.281.0 or later.)
