Continuous Batching

Q: Continuous Batching: 73% Savings with vLLM, TensorRT-LLM, SGLang

From Stripe's 73% inference savings to SGLang's RadixAttention — compare vLLM, TensorRT-LLM, and disaggregated serving stacks in 2026.

Q: From Static Batching to PagedAttention: Prerequisites and Hard Limits of Continuous Batching

See how vLLM's PagedAttention and continuous batching cut KV cache waste to 4% — and where scheduling, prefill, and memory still cap throughput.

Q: How to Deploy Continuous Batching with vLLM, TensorRT-LLM, and SGLang in 2026

Learn which continuous batching engine fits your GPU fleet. Map vLLM, TensorRT-LLM, and SGLang parameters to latency and throughput constraints.

Q: What Is Continuous Batching and How Iteration-Level Scheduling Maximizes GPU Throughput

See why static batching wastes half your GPU budget. Understand how continuous batching in vLLM and TGI slots new requests in at each forward pass.

Q: Request Queues and GPU Access: Who Waits Longest When Continuous Batching Decides

When continuous batching schedules GPUs, some requests wait longer. A fairness lens on priority, queuing, and who gets served first in AI inference.

Continuous batching is a serving optimization for large language models that dynamically groups inference requests and inserts new ones into a running batch as earlier requests finish.

Unlike static batching, which waits for an entire batch to complete before accepting new work, continuous batching fills GPU idle cycles immediately, significantly increasing throughput and reducing per-request latency. Also known as: Dynamic Batching, In-Flight Batching.

What this topic covers

Foundations — Continuous batching replaces the rigid lock-step of static batching with iteration-level scheduling.
Implementation — Deploying continuous batching means choosing a serving framework, tuning queue depths, and managing memory budgets under variable load.
What's changing — Serving efficiency is now the dominant cost lever for production language models, and batching strategies are evolving alongside new hardware and attention kernels.
Risks & limits — Dynamic scheduling introduces fairness questions, from request starvation under heavy load to uneven latency across user tiers.
