TL;DR: AI provider lock-in has moved from procurement friction to continuity risk after model shutdowns exposed how quickly production workflows can break when access changes, according to Kong and cited research from Parallels, Zapier, and the Cloud Security Alliance. Architecture now matters more than contracts because fallback routing, abstraction, and credential isolation determine whether AI services survive provider disruption.
Editorial analysis by NHI Mgmt Group, based on content published by Kong: “# How to Switch LLM Providers Without Downtime”.
By the numbers:
- 94% of organisations are concerned about vendor lock-in, according to Kong.
- A 2026 Parallels survey found that 94% of organisations are concerned about vendor lock-in, according to Kong.
Key questions
Q: What breaks when an LLM provider changes access or goes offline?
A: Applications that call the provider directly fail first, because hardcoded endpoints, model names, and provider-specific authentication leave no rerouting path.
Q: Why does provider lock-in create continuity risk for AI systems?
A: Provider lock-in creates continuity risk because one access change can affect every feature that depends on that model.
Q: What are the signs that an AI failover design is not working?
A: The clearest signs are repeated code changes after provider events, manual rerouting during outages, and separate teams having to rewrite authentication flows for each model change.
Practitioner guidance
- Abstract provider-specific APIs behind a gateway Use a stable request interface so applications do not depend on one provider's endpoint, model naming, or auth flow.
- Define fallback chains and circuit breaker thresholds Set primary and secondary providers, then trigger rerouting on error-rate or latency thresholds before failures reach users.
- Isolate credentials per provider Issue separate API keys or tokens for each provider and give each one an independent revocation path.
Bottom line: LLM provider lock-in is now a continuity issue because provider-specific auth and routing can take production AI workflows offline.

AI provider lock-in is now an identity and continuity problem, not just a sourcing problem. Once an application depends on provider-specific authentication and endpoints, the routing layer becomes part of the access model. That means the resilience question is also an identity question: can the system re-authorise itself against an alternative provider without human intervention? Practitioners should stop separating AI architecture from identity governance when provider access can change at runtime.
A few things that frame the scale:
- AI-related credential leaks surged 81.5% year-over-year in 2025, with the surrounding AI infrastructure leaking 5x faster than core LLM providers, according to the State of Secrets Sprawl 2026.
- Secrets management is a top five cybersecurity priority for only 33% of organisations, behind cloud security (45%), API security (42%), and endpoint security (36%), according to the 2024 State of Secrets Management Survey.
A question worth separating out:
Q: Should teams treat AI provider redundancy as an architecture or governance decision?
A: Both. Architecture determines whether fallback is technically possible, while governance determines who owns provider scope, credential isolation, and failover testing. If those responsibilities are unclear, the organisation may believe it has resilience even when the runtime path still depends on one vendor.
