SiliconFlow (China): SiliconFlow CN free chat models

The terms in full

Standing free-model roster on the CN pricing page, which presents itself as syncing prices in real time and showing only available models, usable at no cost within platform rate limits. Rate limits for the free models are fixed values rather than tiered by spending, and free model calls show as a cost of 0 in the account bill. Specific per-model rate limits are published on the model pages. The roster is dynamically maintained and models can be added or removed; the provider states it retains interpretation rights over which models are free.

• When it runs out Not stated by the provider.
• Clock Standing free-model roster with no end date; dynamically maintained, so composition can change.
• Region China platform (siliconflow.cn and api.siliconflow.cn), operated by a Beijing-registered company. The provider also runs a separate international site at siliconflow.com.
