go/no-go across functionality, cost, reliability, safety, and compliance,
then re-decides while the product stays live. Free vantage-core beside the stack you already run.

The gap
You are about to ship a model or prompt change. The rest of the stack can look green while a quiet miss still reaches your clients. Traces show what happened. They do not render a go/no-go across functionality, cost, reliability, safety, and compliance — and they do not force you to re-prove the critical paths that matter on the next swap.
Example: on Partition Filter Fix, Nova Micro matched Claude Haiku 4.5 at 8.0/10 for roughly 1/32 the sampled cost. Browse benchmarks →
