Moving from another OpenAI-compatible provider in three steps
Move to our uncensored LLM in minutes
Switch to our uncensored LLM by updating your base URL and API key. First, sign up via Google or email to receive your key instantly. Second, set your client’s base_url to HTTPS://api.nsfwllmsystemprompt.com/v1. Third, send requests using model id "uncensored". No complex routing or vendor lock-in. Your prompts stay yours, and you pay only for tokens used.
Common mistakes people make in this niche and how to avoid them
Developers often assume all uncensored LLMs behave identically, yet model architecture drastically alters output quality. Avoid routing errors by strictly sending model: "uncensored" to our single endpoint. Many users underestimate context limits, hitting the 100k token wall or missing the 16k output cap. Configure your SDK base URL to https://api.nsfwllmsystemprompt.com/v1. Verify your key permissions immediately after signup to prevent silent API failures during high-load generation tasks.

Worked cost examples with token arithmetic that use only our prices
Your API bills for actual tokens used. Input costs $0.15 per million tokens. Output runs $0.50 per million tokens. A 5,000-token prompt with a 1,000-token response costs $0.00125 total. This arithmetic uses only our stated rates. Streaming mode does not change the per-token pricing. Errors incur no charge. You pay strictly for what your uncensored model processes.

A checklist for choosing a provider in this niche (6-8 checks the reader can run)
Verify uncensored generation by testing a specific adult prompt against the model's refusal rate. Ensure the API is truly OpenAI-compatible for easy SDK swaps. Confirm your data isn't used for training. Check for prepaid credit that never expires. Avoid hidden routing fees by reading the pricing model. Test streaming support via SSE for real-time chat.
