Main products

• CAISA AI chip
  The CAISA chip is the world’s first mass‑produced AI chip based on a custom dataflow architecture, integrating four CAISA 3.0 engines with up to 10.9 TOPS peak performance and up to 95.4% chip utilization, delivering very high compute‑price efficiency for edge inference workloads. It supports common AI operators and mainstream CNN models such as ResNet, YOLO and DeepLab through flexible operator configuration in the dataflow network.

• Starry Sky X3 accelerator card
  Starry Sky X3 is an AI accelerator card for edge and data‑center inference, based on the CAISA 3.0 dataflow architecture and providing up to 10.9 TOPS with up to 95.4% utilization via a PCIe 3.0 x8 interface compatible with x86 and Arm servers. Using the RainBuilder toolchain, models developed in TensorFlow, PyTorch, Caffe, ONNX (including MXNet, PaddlePaddle) can be seamlessly deployed to X3, enabling high‑performance, low‑latency and cost‑effective acceleration.

• Starry Sky X6A edge box
  The Starry Sky X6A edge station is an intelligent edge computing box built on the CAISA chip, supporting up to 8 channels of HD video decoding and structured analysis for pedestrians, vehicles and equipment defects, with rich interfaces and easy deployment for security, safety supervision, transportation and smart manufacturing scenarios.

• Starry Sky X9 accelerator card
  Starry Sky X9 is a high‑performance AI inference accelerator card integrating four CAISA chips for a total of 43.6 TOPS peak performance, up to 95.7% utilization and sub‑3 ms latency over a PCIe 3.0 x16 interface. It supports up to 64 channels of video structuring, providing high‑throughput, low‑latency acceleration for edge servers running deep learning workloads.

• AI video analytics solutions
  Based on its own chips, accelerator cards and algorithm platforms, Corerain offers integrated AI video analysis solutions for safety monitoring, providing customized high‑accuracy algorithms plus high‑performance hardware to detect personnel behaviors, environmental risks and equipment status in real time in industries such as petrochemical, electric power, ports, cement, steel and construction.

Key advantages

• Innovative dataflow AI chip architecture
  Proprietary CAISA dataflow architecture and RainBuilder end‑to‑end toolchain enable over 10‑times higher effective chip utilization and 2–3‑times measured performance improvement versus comparable products, resulting in outstanding compute‑price efficiency.

• Complete “chip + card + solution” stack
  From AI chips and accelerator cards (X3, X6A, X9) to full AI video analytics solutions, the company provides a full stack of hardware and software that is easy to deploy, highly compatible with mainstream AI frameworks, and tailored to both edge and data‑center inference.

• Strong ecosystem and delivery capability
  With 3 R&D centers, 5 joint laboratories and strategic cooperation with Intel, Inspur, Dell, Phytium and others, plus more than 2,000 partners and over 6,000 projects delivered, Corerain has proven large‑scale implementation experience in smart city, energy and industrial scenarios.
