The Model Provider Webhook Surface You Forgot to Subscribe To
The first time my team found out a model we depended on was being retired, we found out from a customer. The deprecation email had landed in a shared inbox three engineers had unsubscribed from. The provider's status page had a banner up. The webhook event had fired into a void because we never wired up the receiver. Sixty days of warning, used by us as zero days of warning, ending with an outage and a calendar full of "emergency migration" syncs.
Most teams I talk to are running this exact setup right now and don't know it. Every major LLM provider has been quietly building out a notification surface — webhooks for incidents, deprecation events in changelogs, account warnings sent by email, billing anomaly pings, region failover signals — and most teams have it disabled or routed to a mailing list nobody reads. The provider has been telling you the bad news in advance. You've been choosing not to listen.
