DeepSeek’s R1 models

by Posted on

As of the latest available information, DeepSeek’s R1 models (and similar large language models) are typically trained and deployed on high-performance computing hardware, but the specific chips used by DeepSeek have not been officially disclosed in public documentation. However, based on industry trends and the broader AI/LLM ecosystem, we can infer the following:

Likely Hardware Options

  1. NVIDIA GPUs (Most Common for Training LLMs):
    • A100/H100 GPUs: Widely used for large-scale AI training due to their tensor cores and high memory bandwidth.
    • A800/H800: Modified versions of A100/H100 GPUs designed to comply with U.S. export restrictions to China. These are often used by Chinese AI companies due to trade limitations.
  2. Chinese Domestic Chips (Alternative to NVIDIA):
    • Huawei Ascend GPUs (e.g., Ascend 910): Developed by Huawei as part of their MindSpore AI ecosystem.
    • Biren BR100: A GPU from Biren Technology, a Chinese startup, designed for AI workloads.
    • Moore Threads GPUs: Another Chinese company producing GPUs for AI/ML tasks.
  3. Custom ASICs/TPUs (Less Likely but Possible):
    • Some companies develop custom chips (e.g., Google TPUs) to optimize for specific workloads. While DeepSeek has not announced such hardware, future iterations could involve proprietary solutions.

Key Considerations

  • Export Restrictions: U.S. sanctions on advanced AI chips (e.g., H100) to China mean Chinese companies like DeepSeek may rely on domestically produced GPUs (e.g., Huawei Ascend) or modified NVIDIA chips (A800/H800).
  • Scalability: Training models like R1 requires massive GPU clusters. NVIDIA’s CUDA ecosystem (even with A800/H800) remains dominant for such workloads.
  • Inference Chips: For deployment, companies often use cost-effective hardware like NVIDIA T4, A10, or even CPUs (e.g., Intel Xeon) depending on latency and throughput requirements.

DeepSeek’s Public Statements

DeepSeek has emphasized optimizing its models for cost-efficiency and scalability, but it has not explicitly named hardware partners or chip architectures. Their focus appears to be on algorithmic improvements (e.g., reducing training costs by 90% compared to GPT-3) rather than hardware-specific disclosures.

Industry Trends

  • Hybrid Approaches: Many companies combine NVIDIA GPUs for training with domestic/inference-optimized chips for deployment.
  • Open-Source Frameworks: Tools like PyTorch and TensorFlow are hardware-agnostic, allowing models to run on diverse backends (NVIDIA, Huawei, etc.).

Conclusion

While exact details are not public, DeepSeek’s R1 models likely leverage NVIDIA A800/H800 GPUs (due to U.S. export rules) and/or domestic Chinese GPUs (e.g., Huawei Ascend) for training and inference. For precise details, official announcements from DeepSeek would be required.
