Verdict
One API and one bill across hundreds of models from every major lab — the fastest way to arbitrage the model price war and A/B cheaper models without new vendor contracts.
Strengths
- Instant access to new and cheap models the day they launch
- Automatic fallbacks and price-based routing options
- Transparent per-model pricing tables — useful even if you never route through it
Limitations
- Adds a small markup and a third party in the request path
- Enterprise data-processing agreements need review for sensitive workloads
