​

  • Starter access pack: 500,000 prepaid words for $100.00

​
Word Consumption Rates

StealthGPT charges by input words + output words for /api/stealthify, with business mode applying a 10x multiplier. /api/stealthify/articles is a flat 50,000 charged words per request.
The business mode uses a model that is 10x more powerful than the standard engine, providing higher quality and more undetectable content, but it consumes words at a higher rate.

​
Rate Limits

StealthGPT API has the following rate limits to ensure optimal performance and fair usage:
  • 3,500 RPM (Requests Per Minute)
  • 350,000 WPM (Words Per Minute)
