Continuous Batching in vLLM: Killing the Hardware Idle
If your GPUs are idling at 40% utilization during inference, you are burning capital on memory bottlenecks, not computation.

If your GPUs are idling at 40% utilization during inference, you are burning capital on memory bottlenecks, not computation.

Using a 'Draft' model costs 10% more VRAM but saves 50% Latency. Here is the mechanics of the gamble.

As the AI industry moves from model training to large-scale deployment, the strategic bottleneck has shifted from parameter count to inference orchestration. This post explores how advanced techniques like RadixAttention, Chunked Prefills, and Deep Expert Parallelism are redefining the ROI of GPU clusters and creating a new standard for high-performance AI infrastructure.

An end-to-end guide to orchestrating Custom Qwen3 pre-training on Google Cloud's Trillium TPUs. I dive into modifying the Qwen3 architecture for structured JSON outputs, leveraging XPK for orchestration, and serving the final artifacts with vLLM's high-performance openXLA backend.
