🔧 API & Developer Experience

  • OpenAI-Compatible API: A single endpoint mirrors the OpenAI chat-completions format, so most OpenAI SDKs work after swapping the base URL (https://api.siliconflow.cn/v1) and API key — minimal code change to adopt.
  • Unified Model Catalog: Over 100 open-source models (DeepSeek, Qwen, GLM, Kimi, Llama, MiniMax and more) behind one key and one billing account; no per-model signups or separate credentials.
  • Free Tier & Free Models: New accounts receive free credits on signup, and a curated set of serverless models is offered at ¥0 (bge embeddings, GLM-Z1-9B, OCR) for zero-cost prototyping and embedding workloads.
  • Pro Tier: A paid 'Pro' reservation tier buys higher TPQ/throughput and prioritized first-token latency for production traffic, addressing the throughput caps on the free shared pool.
  • Serverless, Pay-Per-Token: You never manage GPUs — SiliconFlow hosts 100+ models on shared clusters and bills per million tokens (input/output/cache), with auto-scaling for traffic bursts.
  • Fine-Tuning & Embeddings: Supported fine-tuning and a full embedding suite (bge-m3, rerankers) make it a one-stop shop for RAG pipelines, not just chat completions.
  • Realtime & Multimodal: Live realtime speech and vision-capable models are listed alongside text, so streaming/voice and RAG use cases share the same API surface.

🧠 China-Native Open-Source Model Hosting

SiliconFlow's core strength is being a China-native, no-infrastructure playground for the open-source ecosystem: it loads 100+ models — DeepSeek, Qwen, GLM, Kimi, Llama, MiniMax and more — onto shared GPU clusters and sells them per token over one OpenAI-compatible API. That removes the two big frictions Chinese teams face elsewhere: signing up for and managing rented GPUs, and cross-border latency. New accounts get free credits and a set of truly ¥0 models (bge embeddings, small GLMs, OCR) for zero-cost prototyping. The trade-off of this breadth is depth: because it mirrors many model families rather than betting on one, per-model optimization and first-token performance trail a dedicated first-party provider, and the fastest 'Pro' throughput requires a paid reservation tier.

🌐 China Access & Latency

SiliconFlow is a mainland-China-native service: the api.siliconflow.cn endpoint is directly reachable from within China without a proxy, with no GFW workaround and no cross-border egress charges, and latency to its Alibaba Cloud-hosted clusters is typically single-digit to low-teens milliseconds RTT. Billing is in RMB via prepaid recharge, and the same account serves the entire open-source catalog. For teams outside China, access follows the typical reverse direction — the mainland-hosted API generally needs a proxy from overseas, and the English documentation is thinner than the Chinese one, so non-Chinese teams may find setup and support lag. The platform is best treated as a China-first serving layer on top of the open-source model ecosystem rather than a globally distributed API.
