Quality verification

The failure mode of open-model serving: the endpoint says deepseek-v4-flash, but what's actually running is over-quantized, mis-configured, or not the model it claims. Keln verifies this at the platform level.

Every route is verified, continuously

Keln verifies that every serving route delivers the model and quality level it claims, using synthetic probes. Verification runs continuously:

• Each route's outputs are compared against trusted references, so serving a lower-precision variant than claimed is detected.
• Routes are scored on test tasks against the other routes serving the same model, which catches degraded quality and silent context truncation.
• A route that fails verification is removed from routing automatically and returns once it passes again.

Conformance before listing

Before any route serves a model, its capabilities are checked end to end: streaming and non-streaming, tool calling, structured output, the reasoning switch. The same checks re-run for as long as the route serves.
