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

$12.00 + $10.80 + $2.10 = $24.90
How much to trust these numbers
Moonshot's new K3.1 series flagship. Cache writes are billed separately at $2/M for a 5-minute TTL or $4/M for a 1-hour TTL; these fees are outside the site's shared rate schema. No K3.1 Foundry rate is listed.
Moonshot's official Kimi Model Inference Pricing page, captured 2026-10-25, lists `kimi-k3.1-pro` at $2/M cache-miss input, $0.20/M cache-hit input, and $10/M output. It lists cache writes at $2/M for 5-minute TTL and $4/M for 1-hour TTL. The official Kimi K3.1 Pro guide identifies the model and documents its 1,048,576-token context. The Microsoft Foundry Kimi pricing table lists K2-family models only, and an Azure Retail Prices query for Foundry meters containing `k3.1` returned no rows on 2026-10-25. The official docs do not give a release or rate-effective date; 2026-10-25 is the first verified capture date. The Highspeed service tier is recorded as a separate variant below.
