DEEPSEEK V4.1 FLASH API PRICING
What DeepSeek charges for DeepSeek V4.1 Flash, in USD, cross-checked daily against the public pricing dataset. Effective price — if there's a promo running, this is the promo.
NOTE: DeepSeek retired V4 Flash and routes this same model ID to V4.1 Flash instead — this is what a real call actually bills today, not the old $0.22/$0.66. Off-peak rate, in force 17 of every 24 hours. Peak (01:00–04:00 and 06:00–10:00 UTC) doubles it: $0.30 in / $1.20 out. Cache hit: $0.003/MTok off-peak.

Source: api-docs.deepseek.com/quick_start/pricing · this price comes straight from the provider, published 2026-10-18. Our daily source still reports the older one, so the automated check deliberately stopped confirming this model on 2026-08-14: we would rather show the number the provider charges than the one our source agrees with.
