Value proposition
Neutral, independent AI infrastructure platform that aggregates heterogeneous compute (NVIDIA, AMD, Huawei Ascend, etc.) with a proprietary inference engine to deliver standardized, high-speed, low-cost token supply for LLMs and multimodal models, enabling developers and enterprises to deploy AI without infrastructure complexity.
Products and solutions
SiliconCloud (one-stop MaaS platform with API services for 170+ models), Reserved Instances (dedicated compute for enterprise inference), Enterprise MaaS Platform (private deployment, fine-tuning, heterogeneous compute management), ComfyUI Cloud Plugin, AI Gateway, BYOK on OpenRouter
Unique value
China's largest independent (non-hyperscaler) token supply platform with a neutral position, proprietary inference acceleration engine delivering 10x+ speed improvements, and support for 170+ open-source and commercial models via a single API — all while maintaining independence from any single cloud ecosystem.
Target customer
AI developers, startups, large internet companies, traditional enterprises, research institutions, government agencies, and AI hardware manufacturers
Industries served
Internet, Education, Government/Public Sector, Smart Computing Centers, AI Hardware, Finance, Manufacturing, Entertainment/Media
Technology advantage
Proprietary high-performance inference engine delivering 10x+ speed improvement for language models and 3x+ for image generation; heterogeneous compute orchestration across NVIDIA, AMD, Huawei Ascend, and domestic Chinese chips; cost optimization achieving 46-66% cost savings; self-developed model inference acceleration and compute scheduling systems
How they differentiate
Positioned as a neutral, independent token supplier — not tied to any single hyperscaler cloud — enabling multi-cloud and cross-ecosystem deployment. First to deploy DeepSeek R1/V3 on domestic Huawei Ascend chips. Aggressive pricing and broadest model selection among independent Chinese MaaS platforms. Serves as the #1 third-party model provider by daily token usage on OpenRouter globally.
