Problem
Large AI models such as Stable Diffusion, generative AI, and modern LLMs require terabyte‑scale memory and high‑throughput tensor processing. Conventional inference servers suffer from memory bottlenecks and fragmented data movement, leading to high latency and inefficient power usage.
Solution
Semidynamics delivers a rack‑level AI inference system that integrates high‑density AI processing units (AIPUs) with a large aggregate RAM pool, creating a terabyte‑scale inference unit. The architecture provides deterministic low‑latency execution for memory‑intensive workloads by eliminating memory stalls and optimizing data movement across a low‑density fabric. By converging silicon and system design, the platform maintains power efficiency while scaling batch sizes for generative models and preserving token throughput for large language models. The solution is offered as a unified hardware package that can be deployed in data centers to accelerate a range of AI tasks without the need for separate memory expansion or custom interconnect engineering.
Target Audience
Primary customers are data center operators, AI research labs, and enterprises running large‑scale generative AI, diffusion models, or high‑throughput image classification workloads.
