Workload cost calculator
Share of input tokens served from cache. Applied only to models with a cache meter.
Rows with a rate that changes by time of day, promo window or service tier are priced for this scenario instead of their flat listed rate; a brand-colored label under the model name names which one applies. Context size for band-priced rows uses the input-token count below.
Picking a specific hour also previews time-of-day rates that are scheduled but have not started billing yet; those rows are labelled · preview with their start instant. Now only ever shows rates that are billable at this moment.
What this lane charges right now
Priced under the workload and scenario above. The full published schedule below always shows every variant regardless of which scenario is selected.
Where this workload's cost goes
60M input tokens (90% cache hit) and 210K output tokens, at the resolved rate above.
$60.00 + $54.00 + $10.50 = $124.50
How much to trust these numbers
GPT-6 Astra Standard Global short-context rate. Microsoft also publishes a $12.50/M cache-write rate; this catalog models cached-input reads, not cache creation.
Microsoft Azure Foundry announcement (https://azure.microsoft.com/en-us/blog/gpt-6-astra-frontier-intelligence-for-work-now-generally-available-in-microsoft-foundry/), published 2026-09-03 and captured 2026-09-05: the GPT-6 Astra pricing table lists Standard Global short context at $10.00/M input, $1.00/M cached input, $12.50/M cached writes and $50.00/M output. A fresh full paged Azure Retail Prices API sweep on 2026-09-05 found no meter containing Astra or GPT-6 yet, so this row follows Microsoft's published Foundry table pending retail-meter publication. Cache writes are outside this schema.
