DeepSeek V4.1 Flash 与 Kimi、Claude 的日常使用成本对比
对比 Kimi K3.1 Pro、Claude/GPT 旗舰与 DeepSeek V4.1 Flash：官方 API 约 200 tok/s、生产环境平均 230、缓存命中 96%，高峰价约 $0.3/$1.2，日常使用更划算。
Kimi K3.1 Pro sits on the edge of the top tier, API list price $2/$10—cheaper than last-gen K3—but that first top-up tier is brutal: $1 gets you 3 RPM and 1.5M tokens/day. Want it to run smooth? Keep feeding it money. Highspeed at $4/$20 trades speed for quota, even worse for casual testing. Claude / GPT flagships? Strong as hell, also absurdly expensive—daily volume basically nopes out. DeepSeek V4.1 Flash: official API ~200 tok/s, production DeepInfer averages 230 (coding can hit 300), cache hit rate 96%. Peak pricing around $0.3/$1.2, half that off-peak—fast, cheap, and quota-friendly. Chase the leaderboard with Kimi / Claude; for day-to-day use, DS is still the practical pick right now.
