User Guide

Task-oriented guides for using BLIS effectively. Each guide covers a specific feature with practical CLI examples and expected output.

Guides

Guide When to Use
Routing (llm-d router) Configuring the embedded llm-d router that distributes requests across instances
Admission Control The router's admission, flow control and request priorities
Scheduling & Priority Controlling request processing order within each instance
Latency Model blis-latency-kernel: what it prices, scenario structure, P/D, DP/EP, speculation, offload, LoRA
KV Cache & Memory Tuning GPU/CPU memory allocation, prefix caching, and chunked prefill
Workload Specifications Defining multi-client traffic patterns with YAML
Cluster Simulation Running multi-instance simulations with the full pipeline
Metrics & Results Understanding JSON output, metrics, anomaly counters, and fitness scores
Observe / Replay / Calibrate Replaying trace workloads (blis replay); observe/calibrate are deprecated (#1901)
Skills & Plugins Claude Code skills, plugin marketplaces, and workflow tooling
