How API billing works

NexusAI itself is completely free. When you use your OpenAI API key, OpenAI charges you directly based on the number of tokens processed. For reference:

  • GPT-4o Mini: ~$0.15 / 1M input tokens, ~$0.60 / 1M output tokens
  • GPT-4o: ~$2.50 / 1M input tokens, ~$10.00 / 1M output tokens
  • DALLΒ·E 3: ~$0.04 per 1024Γ—1024 image

A typical conversation uses 500–2,000 tokens. That's less than $0.01 for most chats on GPT-4o Mini.
