Your business now runs on models, APIs, and agents operated by someone else, and changing without notice. The Agent Assurance Hub watches your endpoints continuously from inside your network, confirms they're working the way you need them to, tells you the moment something changes, and what to do next.
The Agent Assurance Hub is a lightweight service that runs on your terms. It only needs permission to reach the same AI services your company already uses and it does not access sensitive production traffic. Your IP stays yours, guaranteed.
For every model, endpoint, and agent on the watchlist, the Hub keeps answering the questions your teams would otherwise have to take on faith — and delivers each answer to the team that needs it.
Providers can — and do — change what's behind an API without telling anyone. The Hub regularly checks each service and confirms the model answering is the one you approved, whether it's a big-name API, a hosted open model, or AI built into a vendor's product. And when auditors or regulators ask, you have the records to show for it — the kind of evidence frameworks like the EU AI Act expect.
Models get updated, downgraded, or replaced behind the same name and URL. The Hub notices — and records exactly when each change happened, so you know which version was serving your customers on any given day, and when it's time to re-test. No more "it feels different lately" with nothing to point to.
When an AI workflow starts failing, the first question is always "is it us or them?" The Hub tracks the specific behaviors agents rely on — using tools correctly, returning well-formed responses — so your team can tell in minutes whether a problem lives in your code or on the provider's side, instead of losing days to debugging the wrong thing.
Agents evolve — their instructions, memory, and tools change over time, and their behavior shifts with them. The Hub keeps a running picture of how each agent is behaving, so a slow drift off course shows up as a trend you can act on early — not a surprise you discover after it's already caused damage.
If you run OpenRouter, Cloudflare AI Gateway, LiteLLM, or an internal router, keep it — it handles the routing, the keys, and the costs. The Hub answers a different question: can you trust what's on the other end?
Run both. The gateway decides where requests go. The Hub proves what's actually there — and tells you the moment that stops being true.
No changes to your applications, nothing to install in your code, no access to production traffic. Every check the Hub runs is kept as a timestamped record you can look back on later.
The Hub packages monitoring VAIL already runs at scale. Stability Arena is our public dashboard tracking how stable the major models and providers really are — open it and judge for yourself before any conversation.
A continuously updating public view of how models behave across providers — including quiet changes, and the surprising differences between providers serving "the same" model. What the Arena does in public, the Hub does for your services, privately, inside your own network.
Open Stability ArenaThe Hub's checks aren't a black box either. The methods for verifying model identity and detecting change, and for tracking agent behavior over time, are published, peer-reviewed research — presented at ACM CAIS 2026 and ICML 2026.
