Enflame

Enflame, known in China as Suiyuan Technology, is a Shanghai-based semiconductor company founded in 2018 to build data-center accelerators for artificial intelligence. Its products are sold under the CloudBlazer brand and are powered by Enflame's in-house DTU, or Deep Thinking Unit, chips — a training line and a separate inference line aimed at the same large-scale workloads that NVIDIA's data-center GPUs serve. The pitch is straightforward: a domestic Chinese alternative to imported accelerators at a time when US export controls have restricted China's access to the most advanced NVIDIA hardware.

Tencent is Enflame's largest shareholder, holding roughly 20 percent of the company, and is also its dominant customer, accounting for the large majority of recent revenue. That close relationship is both Enflame's biggest asset and its biggest risk: it guarantees demand, but leaves the company heavily dependent on a single buyer. In mid-2026 Enflame won approval for an initial public offering on Shanghai's STAR Market, where it plans to raise about 6 billion yuan — roughly $888 million — to fund its next chip generations. It is widely described as the last of China's so-called "four little dragons" of AI chips to head toward public markets.

Enflame remains a small player by global standards, holding only a low-single-digit share of China's domestic accelerator market against NVIDIA's dominant position, and it has accumulated significant losses while investing in research and development. Its trajectory is best understood less as a near-term challenger to NVIDIA and more as a strategic, Tencent-backed bet on building homegrown AI silicon — where maintaining the option to scale matters more than current profitability.
