One API key for a rotating set of :free model variants, open-weight and stealth models among them
1,000 requests/day per account (after 10 credits purchased all-time)
OpenRouter’s FAQ says its free models “have low rate limits” and “are usually not suitable for production use”, and its limits page warns that a negative credit balance can produce errors “including for free models” and that a 429 can come from the upstream provider rather than the platform (read 2026-09-27). The docs define the daily counter as “Free-model requests recorded so far in the current UTC day”. The higher daily ceiling is granted “starting one credit below the table’s threshold” to absorb rounding and top-up fees.

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.
