New Vantage 2.0 — semantic evals now in general availability

The control plane for production AI

Vantage traces every prompt, scores every response, and routes each request to the model that gets it right. Your team ships on evidence instead of vibes — and finds out about regressions before your customers do.

The platform

Everything between your prompt and production

Three systems that work as one: see what happened, prove it was good, and send the next request somewhere smarter. No sampling, no guesswork, no rewrites.

Traces with nothing left out

Every prompt, tool call, retry, guardrail and token — captured end to end and stitched into a single timeline you can replay. Open any conversation from six weeks ago and see exactly which context the model was holding when it went wrong.

  • Full capture at 100% of traffic, not a 1% sample
  • OpenTelemetry-native, so it lands in the tools you already run
  • PII redacted in-process, before anything leaves your VPC

Evals that block bad releases

Grade responses against your own rubrics, golden datasets and semantic checks — then wire the score into CI. A prompt change that quietly drops answer quality by four points fails the pull request instead of reaching your users.

  • Model-graded, rule-based and human review in one suite
  • Regression gates for GitHub Actions, GitLab and Buildkite
  • Datasets built from real failures with two clicks

Routing that pays for itself

One gateway in front of every provider. Vantage sends each request to the cheapest model that still clears your quality bar, caches what repeats, and fails over in milliseconds when an upstream provider starts throwing errors.

  • Quality-aware routing driven by your live eval scores
  • Automatic failover and retry budgets across providers
  • Per-team spend caps, enforced at the gateway

Customers

We went from arguing about whether the assistant had gotten worse to knowing by lunchtime. Vantage caught a regression in a retrieval change that our own test suite waved straight through — and routing paid for the whole contract in the first six weeks.
