Enflame

Enflame designs and manufactures high-performance, general-purpose AI chips for cloud data centers, focusing on both training and inference workloads. Its business model revolves around providing the hardware infrastructure, specifically accelerator cards and supporting software, necessary for large-scale AI model development and deployment. The company targets a diverse client base that includes internet services, finance, transportation, smart cities, and scientific research sectors. A key partner and investor since its early stages is Tencent, with whom Enflame has collaborated on chip development to serve clients in the financial and transportation industries.

The company's product lineup includes several generations of AI accelerators. The first-generation "CloudBlazer T10" was launched in 2019, based on the "Suisi" Deep Thinking Unit (DTU) chip. Enflame has since released subsequent products for both training and inference, such as the 'Yunsui T10' and 'Yunsui T11' for training and the 'Yunsui i10' for inference, all managed by its 'Yusuo' software platform. The architecture of these chips exploits sparsity to skip unnecessary calculations, enhancing efficiency, and features a proprietary high-speed interconnect for scaling across multiple processors. To remain compliant with international regulations, the company has reportedly submitted downgraded chip designs to its manufacturing partners. Enflame has successfully raised significant capital over multiple funding rounds, with its Series D in September 2023 securing approximately $274 million. The firm began the process for an initial public offering on the Shanghai Stock Exchange STAR Market in August 2024.
