BYOK (Bring Your Own Key) ​

What is BYOK? ​

BYOK means adding your personal API keys from AI providers (OpenAI, Anthropic, etc.) to get unlimited access while paying only for what you use.

How do I get an API key? ​

  1. Sign up at the provider's website (e.g., platform.openai.com)
  2. Go to API Keys section

Yes! Your API keys are:

  • Encrypted at rest
  • Never shared or logged
  • Secure in transmission
  • Deletable anytime

Why did the AI give a wrong answer? ​

AI can make mistakes or "hallucinate." Always:

  • Verify important information

The response was cut off. What happened? ​

Possible reasons:

  • Hit model's max token limit

  • Rate limit reached (with BYOK)

Solution: Ask the AI to continue from where it stopped.
