https://api.siliconflow.com/v1Positive Evidence
Generic docs say free models have fixed limits and paid variants use Pro/ prefixes.Chinese docs say real-name-verified users can use models currently labeled free at zero cost.
Negative Evidence
The current global public catalog gives positive prices to formerly cited DeepSeek-V3 and Qwen3-8B models.The older exact free list contains dated Qwen2-era IDs.No current exact zero-price ID was publicly verifiable without authentication.
China Endpoint Note
The China service may retain a separate real-name-verified free catalog from the global service, but it could not be enumerated anonymously.Recommendation
Require an authenticated model response or billing-free call before treating an ID as current.Receipts
