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.

Unlike 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.

The 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.
