GPT-6 Astra Cost Calculator
Estimate token cost with the published standard rates and automatic long-context multipliers.
Estimate GPT-6 Astra API cost
Enter token usage for a single request. Calculate separate requests individually; do not combine their token totals.
OpenAI states that prompts above 272K input tokens are billed at 2× input/cache rates and 1.5× output rates for the full request.
Estimate excludes tool-call fees and other service-specific charges.
How the estimate works
For standard requests, the calculator uses $10/M uncached input, $1/M cached input and $50/M output. If total entered input exceeds 272K tokens, it applies OpenAI’s published 2× input/cache and 1.5× output multipliers to the full request.
Tool-call fees, service-specific charges and non-standard processing modes are not included.
