SiliconFlow Free Models & Credit
SiliconFlow Free Models & Credit
New users get about ¥14 (≈20M tokens) credit, and after real-name verification can use many permanently free open models (DeepSeek, Qwen, Llama, GLM etc.); free models cost 0 with fixed rate limits.
SiliconFlow (硅基流动) is a domestic MaaS platform with 200+ open models behind one OpenAI-compatible endpoint. Free tier: new accounts receive a credit grant of about ¥14 (roughly 20M tokens of Qwen-class models); after real-name verification, all permanent free variants become available (named without the Pro/ prefix), which cost 0 and have fixed per-model rate limits. Text models generally allow RPM 1,000–10,000 and TPM 50,000–5,000,000 depending on the model and usage tier; image models are limited to IPM 2 / IPD 400. Free policy and limits change, so confirm with the official rate-limit and billing docs.
