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.

How much to trust these numbers
The `deepseek-flash` endpoint now serves V4.1 Flash. Before 2026-09-10 04:00 UTC, this row's base and legacy variants preserve the V4 Flash schedule; from the transition onward, off-peak is $0.15/$0.003/$0.60 and weekday peak is $0.30/$0.006/$1.20 per M (cache hit / cache miss / output order is shown in the source table; the catalog fields are input / cached input / output).
DeepSeek's official API pricing page and September 10 V4.1 Flash announcement, re-read 2026-09-11: `deepseek-flash` is DeepSeek-V4.1-Flash with a 1M context and 384K maximum output; legacy `deepseek-v4-flash` names route to it. The base fields retain the pre-transition V4 Flash off-peak rate for deterministic historical resolution, while the variants below carry the current V4.1 Flash schedule.
