Why Choose NoFilter AI

NoFilter AI provides a dedicated uncensored LLM API designed for developers who need reliability without content moderation layers.

API Features: Streaming, Tools, JSON

The uncensored ai api supports streaming via Server-Sent Events (SSE), allowing real-time token delivery. The final chunk includes token usage details for accurate billing tracking. You can also enable JSON mode with response_format set to json_object for structured outputs.

Function calling is supported via tools and tool_choice parameters. You can control generation with temperature, top_p, stop sequences, seed, and penalties. The model handles long contexts up to 64,000 tokens, with a maximum output of 16,000 tokens per request.

Pricing: $0.25/$1.00 Per Million Tokens

Pricing is straightforward: $0.25 per 1M input tokens and $1.00 per 1M output tokens. You pay only for real usage; errors and refusals are free. There is no monthly subscription or minimum commitment.

Credit never expires. If you make a mistake or get double-charged, contact Support. The uncensored ai models api does not charge for failed requests, so you can test freely once your trial or prepaid balance is active.

Crypto Billing: USDT & USDC

We accept crypto only: USDT on TRC20 or USDC on Base. You can top up any whole amount from $10 to $500. Bonus credits are added automatically: +5% for $50+ and +10% for $100+. No cards, no PayPal, no bank transfers.

Each account gets one active API key. If you generate a new key, the old one is replaced. The api uncensored endpoint works with any whole amount, making it easy to scale your usage without worrying about expiration dates.

Questions and answers

Is NoFilter AI an official OpenAI product?

No. NoFilter AI is an independent service that provides an open-weight model compatible with the OpenAI API format. We do not sell GPT, Claude, or other vendor models. Check the official OpenAI documentation for their specific prices and limits.

What content is blocked?

The model is uncensored for lawful adult, fictional, and controversial topics. However, we enforce a hard limit: sexual content involving minors is always refused.

Can I use this for an AI girlfriend app?

Yes. The uncensored llm api is ideal for AI girlfriend applications because it does not refuse adult topics. You can use the 64k context window to maintain long-term memory and personality consistency.

How do I get my API key?

Go to the Get API key page and sign in with Google or email. Your key is shown immediately. No phone number is required. You can start sending requests right away.

Who is this NOT for?

This API is not for developers who need image generation, audio, video, embeddings, or fine-tuning. It is also not for those who require an SLA, SOC2 certification, or on-prem deployment. It is a text-only API for developers who want uncensored responses.

Your key is one form away

Create an account, copy the key, change the base URL. That is the whole setup.
