R9S: Where AI Finds Its Route. The Agent OS for Modern AI Teams.
Build and orchestrate compound AI systems with unified model access, prompt versioning, semantic caching, real-time evaluation, and enterprise-grade cost controls — all from one platform.
Why Go Through R9S?
You can call models directly — but as your AI workloads scale, you'll face fragmented SDKs, runaway costs, compliance gaps, and zero visibility. R9S solves all of that from day one.
For Agent Developers
BYOK — Zero Lock-in
Bring your own API keys from any provider. Switch models or vendors anytime without changing a single line of code.
One SDK for All Models
Integrate once. Access OpenAI, Anthropic, Google, Qwen, DeepSeek, and 50+ providers through a unified interface with automatic format translation.
Semantic Caching
Intelligent caching recognizes similar prompts and serves cached responses instantly. Cut redundant API calls by 30%+ and slash latency.
Prompt Version Control
Git-like versioning for prompts. A/B test, rollback, and deploy prompt changes independently — no code redeploy needed.
Detailed Billing & Analytics
Track input/output tokens and cost for every single call — more granular than most upstream providers. Know exactly what you're spending.
Observability Dashboard
Get insights most agent developers never see: P95/P99 latency, request volume, error rates, and usage trends — all in a real-time portal.
For Enterprise AI Teams
Governance & Compliance
RBAC, audit logs, data residency controls, and SOC2/GDPR-ready policies. Security and compliance teams sign off with confidence.
Budget Controls & Alerts
Set spend limits per team, project, or API key. Get real-time alerts before costs spiral, with automatic throttling if needed.
Cost Attribution
Know exactly which team, agent, or feature drives your AI spend. Detailed breakdowns for accurate chargeback and forecasting.
Failover & Reliability
Automatic retry with exponential backoff, intelligent fallback to alternative models, and 99.9% uptime SLA for production workloads.
Team Collaboration
Shared workspaces for prompt development. Role-based permissions ensure the right people have the right access to production.
Edge-Speed Performance
Global edge network delivers sub-100ms routing latency. Your users get fast responses no matter where they are.
