100M output tokens for $60: DeepSeek off-peak pricing undercuts Opus 5 by 40x
airesearch12 · x · 2026-09-10
A price comparison of first-party API rates: 100M billed output tokens cost $2,500 on Opus 5, $2,000 on Sol, but just $60 on DeepSeek off-peak ($120 peak) — a 40x gap. DeepSeek's docs show deepseek-flash (V4.1-Flash) with 1M context, 384K max output, peak/off-peak pricing (off-peak at half rate) and 2500 concurrency; deepseek-v4-pro bills up to $1.32/$3.96 per 1M input/output at peak. DeepSeek says V4.1 Flash now comprehensively beats V4 Pro and will retire V4 Pro: from Sept 14, v4-pro requests route to V4.1 Flash at Flash pricing.
