DeepSeek

Peak/off-peak billing window redefined: Chinese public holidays are now explicitly off-peak (50% discount), previously they fell under normal Mon-Fri peak-hour pricing.

DeepSeek merged v4-flash and vision-exp into one deepseek-flash (V4.1) model at lower cache-hit/miss and output prices; new footnote confirms V4 Pro pricing stays unchanged past Sept 14, 2026.

New deepseek-v4-flash-vision-exp model added to the pricing table, priced identically to deepseek-v4-flash ($0.22 off-peak / $0.44 peak per 1M cache-miss input tokens, $0.66 off-peak / $1.32 peak per 1M output tokens, 2500 concurrency); a new footnote states images are converted to tokens by dimension and billed as input tokens, and FIM Completion is not supported. Peak-hours footnote now specifies peak pricing applies Monday through Friday only, so weekends are always billed at off-peak rates; previously the schedule applied every day.

DeepSeek API token pricing restructured from flat rates to peak/off-peak billing (peak 01:00-04:00 & 06:00-10:00 UTC) with a significant increase across both models: v4-flash cache-hit $0.0028→$0.007/$0.014, cache-miss $0.14→$0.22/$0.44, output $0.28→$0.66/$1.32; v4-pro cache-hit 0.003625→$0.022/$0.044, cache-miss $0.435→$0.66/$1.32, output $0.87→$1.98/$3.96 (off-peak/peak per 1M tokens)

DeepSeek replaced its announced peak/off-peak 2x pricing policy notice with a general warning of a significant overall API price increase coming soon. Current listed per-token prices are unchanged.

Announced upcoming peak/off-peak pricing policy: prices will be 2x the regular rate during peak hours (9:00-12:00 and 14:00-18:00 Beijing time, daily), applicable to all billing items; effective date not yet set
