# OpenRouter Performance Tuning

## Overview

OpenRouter adds minimal overhead (~50-100ms) to direct provider calls. Most latency comes from the upstream model. Key levers: model selection (smaller = faster), streaming (lower TTFT), parallel requests, prompt size reduction, and provider routing to faster infrastructure. This skill covers benchmarking, streaming optimization, concurrent processing, and connection tuning.

## Prerequisites

- An OpenRouter API key (`sk-or-v1-...`) exported as `OPENROUTER_API_KEY` — see the `openrouter-install-auth` skill for setup
- Python 3.8+ with the OpenAI SDK (`openai` package) — the examples use both the sync `OpenAI` client and `AsyncOpenAI` for parallel processing
- Credits on the key if you benchmark paid models like `anthropic/claude-3.5-sonnet`; a `:free` model is enough to validate the benchmark harness itself
- `HTTP-Referer` / `X-Title` header values for your app (set in every client constructor here)
