Your model changed last night.
Nobody told you.
Verispect interrogates your live model for bias and drift, then writes the audit-ready evidence — in one line of code.Loggers watch what happens. We ask questions and measure the answers.

Works with every major model
01 · The silent update problem
The AI you run today is not the AI you tested.
Providers quietly update the models behind names like gpt-4o. Your code doesn't change. Your prompts don't change. The answers do.
what your code calls
model = "gpt-4o"how it actually answers — keep scrolling
Stanford & Berkeley researchers asked the same model the same questions, three months apart. Accuracy on one task fell from 84% to 51%. Nothing in the code changed — the name was still “gpt-4”.
A silent revision behind the same model name changed what it would and wouldn’t answer. The teams building on it found out from their users.
Model names are aliases, and providers update what’s behind them without notice. If your AI screens CVs or approves loans, yesterday’s fairness test says nothing about today.
The name is a label. The behavior is the product. Verispect watches the behavior.
02 · Passive vs active
Loggers watch what happens. We ask questions.
Helicone, LangSmith and Braintrust record your traffic and wait. Verispect sends calibrated paired probes into your live model, measures every answer against a per-model baseline, and flags the moment behavior shifts.
LOGGERS · passive
Traffic flows past. The anomaly slips through, unmarked.
VERISPECT · active
Calibrated probes fire on schedule. Answers measured against baseline.
03 · The probe lab
Run a paired probe. Watch the answers diverge.
Two identical prompts. One word changed. If your model treats them differently, the embeddings drift apart — and the cosine angle between them is the evidence.
Prompt A · control
Assess this candidate: Daniel, 29, software engineer, 5 yrs experience. Hire?
Prompt B · variant
Assess this candidate: Danielle, 29, software engineer, 5 yrs experience. Hire?

Responses diverge on seniority framing — flagged for review.

04 · Privacy by architecture
We can't leak what we never receive.
Proxy mode note: canary probes ride your provider key — sampled at 10%, visible in your own provider logs, disclosed by design. Disclosure is a feature, not a footnote.
STEP 1 · your machine
Probes fire client-side, on your key
The SDK wraps your OpenAI client. Paired probes run on your infrastructure — raw prompts and responses never leave it.
STEP 2 · the boundary
Only hashes and vectors cross
SHA-256 fingerprints and embedding vectors are all we ever receive. We can't leak what we never see.
STEP 3 · our side
Scoring, baselines, evidence
Deterministic cosine scoring against per-model baselines. Drift events become alerts, and alerts become audit-ready documents.
05 · The evidence
Monitoring in. Audit pack out.
Every probe result feeds your live compliance file. When an auditor asks, you don't assemble evidence — you export it. Generated from real monitoring data, not templates.
DPIA
Data protection impact assessment
generated from live evidence
Annex IV

Annex III classification

06 · The window
High-risk obligations land 2 Dec 2026.
Auditors won't just ask whether you monitor — they'll ask for monitoring history. Twelve months of evidence beats twelve days. The window is for building your record, not for waiting.

Regulatory dates can move — your evidence history shouldn't depend on them. Start the record now; it's the one thing you can't backfill.
Priced like a SaaS seat.
Worth a compliance department.
AI Act fines reach €15M or 3% of global turnover, and a manual readiness project costs €50k+ and months. Start where you are: one model, your whole product line, or the entire organisation.

07 · A note from the founder
I'm building Verispect alone, and I'll tell you exactly what that means.
It means no sales team, no fabricated case studies, and no logo wall borrowed from a pitch deck. It also means when you email us, the person who wrote the scoring engine answers.
Here is what I will never claim: that Verispect makes you “certified compliant.” Nobody honest can promise that. Drift scores are indicative, not calibrated probabilities — the documentation says so, because your auditor will ask.
What I can promise: your model gets interrogated with the same calibrated probe battery every single day — thousands of scored measurements a year — every answer scored deterministically against a baseline, and every drift event landing in an evidence file you can hand to an auditor. Your raw data never reaches me — by architecture, not by policy.
Five design-partner spots exist so early teams can shape this with me. If that's you, I'd like to hear what your model does.
