Why Chinese models dominate this list

Aggressive domestic competition pushed DeepSeek, Zhipu, Alibaba and Moonshot to price near marginal cost, while capability converged toward frontier level on everything except the very hardest reasoning. For API buyers outside China, the catch has always been access — Chinese phone numbers, local payment, Mandarin docs. Gateways like NovAI exist precisely to remove that friction: one OpenAI-compatible key, card/PayPal/USDT billing, English docs.

Blended-cost example

A support product routing 80% Flash / 15% V4 Pro / 5% frontier pays roughly $0.35 per 1M blended output tokens versus $15+ on an all-frontier stack — a 40x difference for a few points of quality on 5% of traffic.
