Resilience & optimization
Catch a decommissioned model before your users do.
Providers deprecate and remove models constantly — often with little notice. VernaOne keeps a synced catalog of every provider's live models and continuously checks your prompts against it. When a model you depend on goes away, the prompt is paused before it can fail, and you're alerted immediately.

A model disappears, and you find out from a 404 in production
Every provider retires models on its own schedule. OpenAI sunsets snapshots, fal rotates media models, Anthropic and Google move versions to legacy. The moment a model id stops resolving, every prompt pinned to it starts failing — and you usually learn about it from an error spike or an angry customer, not from the provider.
Hardcoded model ids scattered across a codebase make this worse: there's no single place that knows which prompts depend on which models, so an audit means grepping and guessing.
How VernaOne keeps you ahead of it
- 1
A synced, always-current model catalog
VernaOne syncs each provider's full model list into a catalog — endpoint ids, modality, status, and metadata. The picker and router read this catalog instead of hardcoded lists, so what you can select is always what actually exists at the provider today.
- 2
Automatic health-check on every sync
Right after a provider syncs, VernaOne scans every prompt using that provider's models. Any prompt whose model is no longer active is flagged — scoped precisely to the provider that changed, so a sync of one provider never touches unrelated prompts.
- 3
Pause before it fails
If a prompt's model is dead and it has no active fallback, VernaOne automatically pauses the prompt. A paused prompt rejects execution instead of throwing provider errors at your users — the failure is contained the instant it's detected.
- 4
Warn when a fallback saves you
If the dead model has an active fallback in the chain, the prompt keeps running on the fallback and VernaOne raises a warning instead — so you're not paged at 3am for something that's already self-healing, but you still know to update the primary.
- 5
Alert every way that matters
Every finding lands in the alert log and a persistent in-app banner, and — for paused prompts — an immediate critical email to the project's alert recipients (or the account owner), with a daily reminder while the prompt stays paused. Alerts auto-resolve the moment you fix the prompt.
Highlights
Live model catalog
Per-provider sync keeps the selectable models identical to what the provider actually serves — no stale hardcoded lists.
Auto-pause on dead model
No active fallback means the prompt is paused before it can fail, containing the blast radius instantly.
Fallback-aware warnings
A prompt still covered by an active fallback gets a warning, not a page — noise stays low, signal stays high.
Email distribution + daily reminders
Configurable recipient list per project, owner fallback, immediate critical email, and a daily nudge until it's resolved.
Persistent in-app banner
A banner surfaces every paused/warning prompt with a deep link straight to the version that needs a new model.
Auto-resolve
Assign a supported model or fallback and the alert clears itself — no manual acknowledging, no stale warnings.
The health-check is scoped to the synced provider, is idempotent per (prompt, dead model), and never blocks or fails the sync itself — detection is a safe, background side effect.
Ship on this — free to start.
Author a prompt once and call it by name. VernaOne handles the model, the fallback, the cost, and the alerting.

What happens when a model I use is deprecated?
As soon as VernaOne syncs the provider and sees the model is no longer active, it checks every prompt using it. If the prompt has no active fallback, it's paused and you get an immediate critical alert and email. If it has an active fallback, the prompt keeps running on the fallback and you get a warning to update the primary.
Will a paused prompt silently drop traffic?
No — a paused prompt rejects execution with a clear status rather than failing against a dead provider endpoint, and it's surfaced loudly in the alert banner, the alert log, and an email. The pause is a containment mechanism, not a silent drop.
Who gets the alert emails?
Each project has an alert-recipients distribution list you configure. If it's empty, alerts go to the project owner. You get an immediate critical email when a prompt is paused, plus a daily reminder while it stays paused; the alert auto-resolves when you fix it.
Does checking one provider affect prompts on other providers?
No. The health-check is scoped to the provider that was just synced, so syncing fal only ever evaluates fal-backed prompts. Unrelated prompts are never touched.
Can I get alerts in Slack or a webhook?
Email is live today with a configurable per-project recipient list. Slack and webhook channels are on the roadmap — the alert dispatch is already funnelled through one place, so additional channels are a localized addition.
