One provider is a single point of failure
When your only model provider has an outage, every request fails at once — and you find out from angry users, not a dashboard.

Control Cost & Risk
Survive a provider
outage without downtime.
Bring your own provider keys and define a routing order behind one intent contract. Keep provider selection out of application code and make failover behavior explicit.
Start with your domainKeep ownership and runtime context with the team that operates the capability.
Expose a clear contractIntegrate through a named intent instead of coupling product code to prompts.
Improve from evidenceTest and observe the same execution path your application calls.
Where teams get stuck
The prototype is easy. The operating model is not.
Production problems appear when prompts, provider logic, policy checks, and debugging are split across application services with no shared owner.
Hotwiring a fallback under pressure is risky
Writing failover logic during an incident means shipping untested code while the site is already down — exactly the wrong moment.
Provider lock-in blocks negotiation
Without a real fallback path, you can't credibly threaten to leave — and you're stuck paying whatever a single vendor decides to charge.
Production pattern
A direct path from business outcome to callable AI.
LiyaEngine keeps the capability surface simple while the infrastructure behind it remains governed and observable.
01
Own the capability
Create a tenant-owned domain and define the intent contract your product needs.
02
Connect the context
Link knowledge, tools, model configuration, and policies without changing the application interface.
03
Test the behavior
Run representative requests, review structured output, and inspect the full execution path.
04
Operate with evidence
Use traces, evaluations, usage, and cost context to improve the capability after launch.
How LiyaEngine helps
Move infrastructure out of the product code path.
Model routing sits behind the intent contract. Configure supported providers or a compatible custom endpoint, then define the deterministic order your application should use.
On any error from the primary — including auth failures — the engine immediately retries against the next provider in your fallback chain, using your own keys and your own billing. Same request, same response shape.
