Streaming makes responses feel fast, but it creates a hard recovery boundary. Learn when an LLM request can fail over safely, why emitted tokens cannot be replayed silently, and how clients should handle partial output.
Provider breadth behind a single OpenAI-compatible key. What the swap changes in your codebase, what the model string buys you, which providers are live today, and the integration work that stops being yours to maintain.
Moving an OpenAI-compatible app from OpenRouter to nRouter is two lines of config. The work that is actually left is model-slug mapping, the vendor extensions you added, and a cost-and-error contract that behaves differently. Here is the whole checklist.
Point your Anthropic client at one gateway base URL and every Claude call arrives with a hard budget, a fallback path, a per-request cost header, and a team it can be billed to. No SDK rewrite, no provider key to paste.
nRouter is a managed LLM gateway. One OpenAI-compatible key reaches every model in your catalog, every response carries its exact cost, and guardrails, budgets, A/B tests and prompt management are on every plan, not gated.
