## Key facts

- **Founded:** August 29, 2023 in Beijing by [Yuan Jinhui](/people/yuan-jinhui.md), previously founder of the OneFlow deep-learning framework
- **Core product:** SiliconCloud, a serverless multi-model inference API hosting 200+ LLMs and multimodal models with an OpenAI-compatible interface
- **Positioning axis:** Inference-focused, long-tail-model aggregator. No publicly disclosed owned GPU fleet or datacenter capacity; operates as an inference-optimization layer atop partner infrastructure
- **Market position (China):** Ranked #4 in China token-throughput market in 2025 at ~1.5% share; #1 among independent (non-hyperscaler) token suppliers
- **Announced pricing (LLM):** Per-token: DeepSeek family $0.13–$1.50 per 1M input tokens; Qwen family $0.10–$0.30 per 1M input; Kimi family $0.45–$3.00 per 1M input
- **Announced pricing (multimodal):** Image generation $0.014–$0.08 per image (FLUX.1 family); video generation $0.29 per clip on Wan2.2
- **Models served:** DeepSeek (incl. V4-Flash with 1M-token context), Qwen, GLM-5.2, Kimi, Google Gemma, FLUX.1 (image), Wan2.2 (video), plus audio TTS/ASR
- **Open-source projects:** OneDiff (diffusion-model inference engine) and BizyAir (AI-native scalable inference runtime)
- **Series B (most recent round):** June 2026: raised more than RMB 2 billion (~USD 280M) at post-money RMB 7.74 billion (~USD 1.08B)
- **Earlier funding:** Angel (2024) led by Innovation Works; Pre-A (2024) led by China Innovation Funding with Puhua Capital and Yaotu Capital; Series A (June 2025) of hundreds of millions RMB
- **Strategic investor:** Meituan took a strategic stake in 2025; other listed backers include Huachuang Capital and Innovation Works
- **Public-market status:** Private; filed IPO application with the Hong Kong Stock Exchange in June 2026
- **HQ address:** Zhongguancun East Road No. 1, Building 8, Tower D, 23F, Haidian District, Beijing
- **GPU inventory and MW capacity:** Not disclosed. SiliconFlow does not publicly report owned GPU counts, silicon-vendor mix, or datacenter megawattage; it presents as a serverless inference layer rather than an infrastructure owner

## Common questions

### What is SiliconFlow?

SiliconFlow (硅基流动) is a Beijing-based AI infrastructure startup founded in August 2023 by Yuan Jinhui, the same engineer who previously built the OneFlow deep-learning framework. Its flagship product, SiliconCloud, is a serverless inference API that hosts more than 200 open and open-weights models, including DeepSeek, Qwen, GLM, Kimi, Meta Llama derivatives, FLUX image models, and Wan2.2 video generation. The platform bills per token rather than per GPU-hour and positions itself as an OpenAI-compatible substitute in the Chinese market.\n\nUnlike Western neoclouds such as CoreWeave or Lambda, SiliconFlow does not publicly disclose owning datacenter capacity or GPU fleets of its own. It operates as an inference-optimization layer that runs across partner infrastructure, and its public materials emphasize a proprietary inference engine plus open-source projects (OneDiff for diffusion, BizyAir for scalable inference) rather than a physical footprint. Chinese-market disclosures rank it fourth in national token throughput for 2025 at roughly 1.5 percent market share, and first among independent (non-hyperscaler) token suppliers.\n\nThe company scaled quickly on the back of the DeepSeek wave. After an Innovation Works-led angel in 2024 and a Pre-A led by China Innovation Funding, it raised a Series A of hundreds of millions of RMB in June 2025 with Meituan taking a strategic stake, then closed a Series B in June 2026 of more than 2 billion RMB at a post-money valuation of about 7.74 billion RMB (roughly USD 1.08 billion), and filed for a Hong Kong Stock Exchange listing the same month.
