Dolphin LLM uses transparent pay-as-you-go pricing for our uncensored AI model, ensuring you only pay for the tokens you actually consume. There are no hidden fees, subscriptions, or expiration dates on your prepaid balance.
Top-ups from $20 to $500, by card or crypto (USDT, USDC). Bonus credit: +5% from $50, +10% from $100, +15% from $200.
Running a 4,000-token system prompt for a long-running roleplay session that generates 2,000 tokens of story content.
Input cost: 4,000 / 1,000,000 × $0.15 = $0.0006. Output cost: 2,000 / 1,000,000 × $0.50 = $0.001. Total cost: $0.0016.
Processing a 10,000-token code snippet to get a 500-token explanation.
Input cost: 10,000 / 1,000,000 × $0.15 = $0.0015. Output cost: 500 / 1,000,000 × $0.50 = $0.00025. Total cost: $0.00175.
A heavy batch job sending 50,000 tokens of context and receiving 10,000 tokens of structured JSON output.
Input cost: 50,000 / 1,000,000 × $0.15 = $0.0075. Output cost: 10,000 / 1,000,000 × $0.50 = $0.005. Total cost: $0.0125.
The Dolphin LLM API charges based on token volume rather than a flat monthly subscription. Input tokens cost $0.15 per million, while output tokens are priced at $0.50 per million. This structure reflects the compute intensity of generating text compared to processing your input. You can monitor your exact token usage in your account, so you always know what you are spending on your uncensored LLM chat sessions.
We encourage developers to top up their accounts with larger amounts to receive bonus credit. Top-ups start at $20, and bonuses kick in at higher tiers: a $50 top-up grants a 5% bonus, a $100 top-up a 10% bonus, and $200 or more a 15% bonus. These bonuses are added to your balance immediately, extending the life of your credit without changing the underlying per-token rates.
Unlike many other services that wipe your balance after a few months, prepaid credit on Dolphin LLM never expires. Once you have loaded funds, they remain available for your uncensored AI model usage indefinitely. This is ideal for long-term projects or developers who prefer to buy credit in bulk and use it at their own pace without worrying about time limits or losing their investment.
Same price for every feature: function calling and JSON mode cost nothing extra.

No. New accounts receive $0.50 in trial credit valid for 7 days, requiring only an email and password. The credit is added when you open your account. You can add funds later by card or with crypto (USDT, USDC) when you are ready to scale your usage.
No. Since this is a prepaid system, you can only spend what you have loaded. If your balance hits zero, requests will stop until you add more credit. This keeps your spending predictable and prevents surprise bills.
Tokens are the basic units of text processed by the model. Roughly, one token is about four characters for English text. The API counts every token in your prompt (input) and every token in the generated response (output) separately.
There are no hidden fees. You only pay for the tokens used. There are no monthly subscription fees, no per-request fees, and no costs for the API endpoint itself. The only costs are the input and output token rates listed above.
Create an account, copy the key, change the base URL. That is the whole setup.
