Frequently asked questions
Plans, limits, models, payment and privacy. If something is missing, the features page goes deeper on what the product does.
- What is Tartarus AI?
- Tartarus AI is an uncensored AI assistant. You ask questions in a browser and get streamed answers from one of three models with reduced refusal training, with web search, a reasoning view, conversation branching and an optional OpenAI-compatible API.
- What does "uncensored" mean here?
- It means the models have reduced refusal training and there is no moderation classifier reading the output, so legitimate work is not refused for resembling something else. It does not mean there are no limits: the acceptable use policy in the terms is the authoritative list, and it is short.
- Is Tartarus AI really unrestricted?
- Restrictions that come from refusal training and output filtering are reduced or absent. Restrictions that come from law and from our acceptable use policy remain, and we would rather say so than let you discover it later. We do not permit material that sexualises minors, attacks on systems you do not own, or use of the service to defraud or threaten real people.
- Does removing refusal training make the model less accurate?
- Refusal and accuracy are unrelated, so it does not improve accuracy either. A model that will answer a question it once declined is not better informed about it, and a confident wrong answer is more dangerous than a refusal was. Verify anything consequential.
- How much does Tartarus AI cost?
- Plans start at $20 per month for Basic, $40 for Standard, $60 for Pro and $100 for Ultra. Paying for three months takes 10% off and twelve months takes 20% off. There is no per-request billing on any plan.
- Is there a free plan?
- No. A registered account starts with no usage allowance, so signing up puts you on the plan picker rather than on free inference. Promotional trial windows are opened occasionally and announced on the site when they are.
- Can I pay with a credit card?
- No. Plans are prepaid in cryptocurrency: USDT on TRC20 or ERC20, Bitcoin, Ethereum, Litecoin, Tron or Monero. Nothing is stored against a card and nothing renews automatically, so there is no subscription to cancel.
- What is the difference between the Fast, Balanced and Deep models?
- Fast answers immediately and suits everyday questions, writing and summaries. Balanced thinks briefly first and is a good default for most work. Deep reasons at length before answering and suits multi-step or analytical problems.
- What is a token, and how far does a weekly allowance go?
- A token is roughly three quarters of an English word, counted across both what you send and what the model writes back. The 15M weekly allowance on Basic covers steady daily use by one person; the plans above it double at each step for longer documents, heavier days and API traffic.
- Can I use Tartarus AI from the command line or from my own code?
- Yes, on the Pro plan. It mints tokens for an OpenAI-compatible endpoint, so pointing OPENAI_BASE_URL and OPENAI_API_KEY at Tartarus AI makes existing clients, SDKs and editor integrations work unchanged.
- Does Tartarus AI train on my conversations?
- No. Conversations are stored so you can come back to them and are deleted when you delete them. They are not used to train models.
- Can Tartarus AI search the web?
- Yes. When a question needs current information the model runs a search and reads the pages it finds, and the sources are listed above the answer so you can check them.
- What happens when I reach my weekly limit?
- Generation pauses until the allowance resets at the start of the next week. Your conversations and history stay available the whole time, and moving to a larger plan lifts the limit immediately.
- How large a context can I send?
- Basic accepts 32K tokens of context, Standard 128K and Pro 200K. A quarter of the window is held back for the reply, so the usable prompt is about 24K, 96K and 147K. In the browser, older turns are trimmed automatically to fit rather than failing the request; over the API an oversized request is rejected so your client can compact and retry.
- Do I need an account to try it?
- You need an account to chat. Registration takes an email address and a password, or a Google sign-in, and email verification is required before the first message.
