Examples

Short text generation

Cost for 10,000 input tokens and 2,000 output tokens: (10,000 / 1,000,000 * $0.25) + (2,000 / 1,000,000 * $1.00) = $0.0025 + $0.002 = $0.0045.

Medium-length analysis

Cost for 50,000 input tokens and 10,000 output tokens: (50,000 / 1,000,000 * $0.25) + (10,000 / 1,000,000 * $1.00) = $0.0125 + $0.01 = $0.0225.

Long context processing

Cost for 200,000 input tokens and 50,000 output tokens: (200,000 / 1,000,000 * $0.25) + (50,000 / 1,000,000 * $1.00) = $0.05 + $0.05 = $0.10.

Pay as you go Model

Our uncensored AI API gives you full control by eliminating subscription dependency. Unlike standard large language models, there are no monthly fees or tiered plans; you only pay for what you use. Our system works with an OpenAI-compatible structure, but our model is fine-tuned to generate direct responses without content rejection. This model simplifies budget planning, especially during high-volume data processing or peak usage periods. The cost of each token is known in advance, so you won't face any surprise bills.

Per-Token Costs

Our cost structure is transparent and straightforward. Input tokens are charged at $0.25 per million tokens, while output tokens are $1.00 per million. This rate remains consistent even for long context window (100k token) usage. Every API request for nsfw or other content types is subject to these rates. For example, when generating a long story or producing a complex code block, the output cost will be higher than the input cost. This reflects the generative nature of the model and allows you to calculate your costs clearly based on your use cases.

Bonus Credit Structure and Payment

You earn bonus credit based on the amount you top up to our system. Starting with deposits of $10 or more, you receive 5% bonus on transactions of $50 or more, and 10% bonus on transactions of $100 or more. These bonuses are used together with your main balance and never expire. We support crypto payments (USDT or USDC). A $0.50 free trial credit is provided for each new account without requiring card details, valid for 7 days. This way, you can experience real usage before testing the speed.
