About DeepSeek

DeepSeek publishes open-weights models at disruptive prices. Even after its August 2026 switch to peak/off-peak billing, the V4 line costs a fraction of Western equivalents, off-peak hours (everything outside 01:00–04:00 and 06:00–10:00 UTC on weekdays) halve the bill again, and V4.1 Flash added native vision in September at $0.30/$1.20 peak.
