DeepSeek V4.1 Flash vs Kimi K3.1 Pro and Claude on daily-use cost
Compares Kimi K3.1 Pro, Claude/GPT flagships and DeepSeek V4.1 Flash: official API ~200 tok/s, 230 in production, 96% cache hit rate, peak pricing around $0.3/$1.2, making it the practical daily pick.
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.
