- ✗ Manage 5+ provider APIs separately
- ✗ No fallback when a model fails
- ✗ LLM invents plausible-sounding facts
- ✗ Hard to track cost, latency, accuracy
- ✗ Build retry, rate limiting, caching yourself
- ✓ One API — best model auto-selected per query
- ✓ Built-in fallback — transparent provider failover
- ✓ Every answer verified — citations + confidence score
- ✓ Audit trail included — model, latency, grounded status
- ✓ Production-hardened — retry, rate limiting, tenant isolation
When evidence is weak, we say so.
If the documents don't contain enough evidence, we return:
- Low confidence score
-
grounded: false - Or no answer at all
So your users never get misleading information.
