OpenRouter launches Activity Explorer dashboard

Providing real-time, granular observability into LLM spend and behavior is crucial for production deployments, especially as autonomous agents and complex prompt caching strategies become standard.

• –**Rogue Agent Mitigation:** Grouping spend by user and agent makes it easy to detect looping or runaway agent workflows before they result in massive bills.
• –**Prompt Caching Insights:** Clear visibility into cache hit rates allows developers to benchmark and adjust context length strategies to maximize caching efficiency.
• –**Unified Security & Compliance:** Surfacing prompt injection and PII violations directly within the activity stream integrates security monitoring into the core developer dashboard.
