FAQ
Is ChatGPT subscription the same as Astra API pricing?
No. A ChatGPT / Plus / Pro subscription is separate from metered API usage. This calculator estimates API token costs only.
Is this official OpenAI pricing?
No — this site is unofficial and not affiliated with OpenAI. Use it for rough planning, then verify on the official docs:
When does the 272K long-context cliff apply?
OpenAI describes higher rates for prompts with more than 272K input tokens. Here we treat cliff trigger as uncached_input + cached_input > 272000, and when triggered we multiply the whole request’s input/cache rates ×2 and output ×1.5. See 272K pricing explained.
What are Batch, Flex, and Fast?
Batch and Flex are modeled as half Standard rates; Fast as double the applicable rates (after any cliff). Exact product names and availability can change — confirm on OpenAI’s pricing page.
