Continuous Batching for LLM Inference: How It Works and When to Use It
A deep technical explainer on continuous batching for LLM inference: why static batching wastes GPU compute on autoregressive generation, how iteration-level scheduling works, the prefill vs decode phase distinction, PagedAttention and KV cache memory management, throughput vs latency tradeoffs, and vLLM configuration parameters for tuning continuous batching in production.
