featuresCustom classifiers let you define a structured taxonomy and use a model of your choosing (OpenRouter will recommend fast, inexpensive models during classifier setup) to tag and classify your prompts. The classifier model runs asynchronously after each request completes (zero added latency), tagging generations with dimensions like department, task type, complexity, or anything you can think of. Tags appear in your logs, and roll-up reporting is available in your activity view. Together, these help you understand how AI is being used across your organization.https://openrouter.ai/docs/guides/features/classifiers
featuresFor organization accounts, only org admins can see classification tags on log rows and in the generation detail panel. Workspace admins who aren’t org admins can create and manage classifiers but don’t see the resulting tags. Filter and analyze your classified generations in the Activity and Logs views, or with the [API](#query-classifications-with-the-api).https://openrouter.ai/docs/guides/features/classifiers
featuresIn-Region Routing (IRR) processes the prompts and completions in your requests within a designated region. When you send a request through a region-specific base URL, the request is decrypted within that region and routed only to shared provider endpoints in that region: Europe (the EU/EEA, the UK, and Switzerland) for `eu.openrouter.ai`, and the US for `us.openrouter.ai`. If no endpoint eligible for the region (shared, BYOK, or private) can serve the request, it errors instead of leaving the region. Requests served by your own BYOK key go to your deployment’s region, which you control. Account and operational records are handled separately; see [What stays outside the region](#what-stays-outside-the-region). EU in-region routing (`eu.openrouter.ai`) and US in-region routing (`us.openrouter.ai`) are available on the Business and Enterprise plans. There is no setting to turn on: once your account is on one of these plans, you choose the region for each request by sending it to that region’s base URL. Organization admins can upgrade to Business in Settings > Manage plan. For Enterprise, contact our enterprise team.https://openrouter.ai/docs/guides/features/in-region-routing
featuresSome providers bill a premium for serving a model from a specific region. On the global domain (`https://openrouter.ai`), default routing skips these regional-surcharge endpoints whenever the model also has a standard-priced endpoint. The model page lists them under Not used in Standard routing. That grouping describes shared routing without your BYOK keys, so an endpoint that only your own key unlocks still appears there. A regional-surcharge endpoint is used when:https://openrouter.ai/docs/guides/features/in-region-routing
featuresA request that arrives through a domain not in the list is rejected with a 403 Forbidden error before any inference or endpoint selection happens, so no prompt is ever processed outside the permitted regions. Leaving the setting unrestricted (`null`) accepts requests from any domain. Enforcement applies to every OpenRouter API surface, including chat completions, embeddings, rerank, image, audio, and video generation, server tools, the Batch API, and generation lookups. When more than one guardrail governs a request (the workspace default guardrail, the member’s guardrail, and the API key’s guardrail), the effective set of regions is the intersection of every guardrail that sets one, so a lower-level guardrail can only narrow the regions permitted above it. For example, if the workspace default guardrail allows `europe` and `us` and an API key guardrail allows only `europe`, requests with that key must arrive through `https://eu.openrouter.ai`. To enforce EU residency for a whole workspace, set `allowed_data_regions` to `["europe"]` on the workspace default guardrail. This can be configured in the guardrail editor under Data regions or through the Guardrails API.https://openrouter.ai/docs/guides/features/in-region-routing
featuresIn-region routing covers the prompts and completions in requests sent to a regional domain and served by shared provider endpoints. Account and operational records, BYOK deployments, and destinations you configure are outside that boundary. For `eu.openrouter.ai`:https://openrouter.ai/docs/guides/features/in-region-routing
featuresNavigate to your **Observability** settings and toggle Input & Output Logging to enable it. For organizations, only admins can view and toggle this setting.https://openrouter.ai/docs/guides/features/input-output-logging
featuresRetention: Data is retained for a minimum of 3 months, and may be retained beyond 3 months at OpenRouter’s discretion unless you request deletion. Account owners can request deletion of their stored data at any time by contacting support@openrouter.ai.https://openrouter.ai/docs/guides/features/input-output-logging
featuresPrivacy: OpenRouter does not access or use your prompt and response data logged with this feature for model training, analytics, or any other purpose. The data is stored solely for your own review and use. See the Privacy Policy for full details.https://openrouter.ai/docs/guides/features/input-output-logging
featuresInput & Output Logging allows you to view your prompts and completions in your logs on the OpenRouter platform. Broadcast sends your data to an external observability tool. Both features are configured in your workspace’s Observability settings and can be used together for comprehensive observability.https://openrouter.ai/docs/guides/features/input-output-logging
