Disaggregating Large Language Models: Advancing the Future of AI Infrastructure

Unlocking the Future of AI with Disaggregated LLM Inference

As AI models grow more powerful, optimizing their infrastructure is crucial. Disaggregation in large language models (LLMs) offers a solution, transforming how businesses leverage AI for efficiency.

Key Insights:

  • LLM Inference Phases:

    • Prefill Phase: Achieves 90-95% GPU utilization, processing input context efficiently.
    • Decode Phase: Operates at 20-40% GPU utilization, generating outputs with higher latency.
  • Disaggregated Architectures:

    • Separate prefill and decode tasks onto optimized hardware clusters.
    • Enhance performance with frameworks like vLLM, SGLang, and TensorRT-LLM—demonstrating up to 6.4x throughput improvements.
  • Cost Efficiency:

    • Organizations can cut infrastructure costs by 15-40% while improving GPU utilization and energy efficiency.

Why it Matters:
Transitioning to disaggregated serving architectures is essential for businesses aiming to enhance their AI deployments.
