Part 6 of “vLLM in 2026: An Infrastructure Engineer’s Field Guide” For years, training and inference were separate worlds with separate clusters and separate teams. That boundary is dissolving. Reinforcement learning turns your inference engine into part of the training loop. Speculative decoding needs draft models that must be trained against the target you serve.
Part 5 of “vLLM in 2026: An Infrastructure Engineer’s Field Guide” Quantization is the closest thing inference has to a free lunch, and it isn’t free. Cutting precision shrinks weights, shrinks the KV cache, and speeds up memory-bound decode. It also risks quality regressions that don’t show up until a user finds them. This post
Part 4 of “vLLM in 2026: An Infrastructure Engineer’s Field Guide” Capacity planning for chat was relatively simple: users send a prompt, the model streams an answer, and you size for concurrent conversations. Agents change the traffic shape completely. A single user request can fan out into dozens of model calls, each with a growing
Part 3 of “vLLM in 2026: An Infrastructure Engineer’s Field Guide” If you’ve designed a lossless RoCEv2 fabric or debugged NCCL rings, you already know most of what matters here. Serving a frontier-scale model is no longer “one model on one GPU.” It is a distributed system whose performance is set by collectives, KV cache
