FAQ

Frequently asked questions

What is Paralon AI?

Paralon AI is an OpenAI-compatible inference API powered by a distributed network of high-performance GPUs. You can use the same code you'd use with OpenAI, just change the base URL to paraloncloud.com/v1.

Which AI models are available?

We offer a variety of popular open-source LLMs optimized for different use cases. Models are dynamically loaded based on network availability. Check our /models endpoint for the current list.

Is there a free tier?

Yes. Every account gets one free API key with a 250,000-token trial, 5 images a day and 20 requests per minute. No credit card required. Just sign in and start building; premium keys bill per token from prepaid credits.

How do I integrate with my existing code?

If you're using the OpenAI SDK, simply change the base_url to 'https://paraloncloud.com/v1' and use your Paralon API key. The API is fully compatible with OpenAI's chat completions format.

Can I use Claude Code with an open model here?

Yes. The API also answers Anthropic's Messages format at /v1/messages, so Claude Code needs no router in between: set ANTHROPIC_BASE_URL to https://paraloncloud.com, ANTHROPIC_AUTH_TOKEN to your key, and the model variables (ANTHROPIC_MODEL, ANTHROPIC_SMALL_FAST_MODEL and the ANTHROPIC_DEFAULT_HAIKU, SONNET and OPUS ones) to qwen3.8-27b.

Is my data secure?

Yes. We use HTTPS everywhere, authenticate all requests with API keys, and do not retain prompt data after processing. Your conversations are not used for training.

What's the latency like?

Our distributed GPU network provides low-latency inference. Most requests complete in under 1 second for initial response, with streaming available for real-time token delivery.
