A six-turn conversation is not simply six identical calls if prior messages are resent. This calculator approximates the history carried forward so you can budget a production support or assistant experience more realistically.
The math
Actual invoices can differ because providers may apply long-context pricing, caching rules, batch rates, tool-call fees, regional processing, negotiated contracts, taxes, or future pricing changes. Treat the output as a planning estimate.
Pricing sources
Current model rates are sourced from official provider pricing pages and verified on August 28, 2026. The methodology page records the source links and known limitations.
Frequently asked question
Does conversation history increase cost?
Yes when prior turns are included in later requests. Trimming, summarizing or caching repeated context can reduce billed input.
Can I use this estimate for a production budget?
Use it to create scenarios and catch order-of-magnitude mistakes. Before committing spend, verify the selected model's live provider pricing and compare the estimate with actual usage telemetry.
