Why I use it

Its job in the stack

I use OpenRouter to compare model families and give compatible tools a consistent route to several providers. It is useful when the work needs choice or fallback without a separate integration for every model.

The additional layer needs scrutiny. Model identity, provider routing, data policy and cost must remain visible rather than disappearing behind a convenient endpoint.

Where it earns its place

Work I use it for

  • 01Cross-model evaluation
  • 02Provider fallback
  • 03Unified API access
  • 04Cost and capability routing

Limits

What it does not solve

Routing adds another dependency and policy surface. Sensitive work requires confirmation of the selected provider and retention terms.
