Zero-priced small chat models on SiliconFlow China, after real-name verification with accepted mainland, Hong Kong, Macau or Taiwan documents
Free models are zero-priced but require real-name verification. Online verification uses an Alipay face scan and accepted mainland, Hong Kong, Macau, Taiwan or Chinese permanent-residence documents; other applicants must contact staff. Sign in by SMS or email. Per-model fixed rate values are shown in the client-rendered model square, rather than public docs.
