Evaluation Builder

Quality infrastructure for AI assistants and agents

Build custom LLM judges, golden datasets, and regression workflows around the AI system you already ship.

First evaluator free · No card required

From existing AI assets to a runnable quality layer.

Define what “good” means. Generate the right test cases. Build judges that reflect your product. Regression-test every change before production.

Without infrastructure

  • Only “correct” gets measured
  • Edge cases live in someone's head
  • Every release argues what's better
Quality over time → declining

With Argmin AI

  • Reusable rubrics, datasets, judges
  • Edge cases tested before they ship
  • Version comparisons show what changed
Quality over time → improving

“Correct” is not enough. We build the quality infrastructure

01

Correctness & substance

  • Accurate
    Correctness rubric with explanations
  • Grounded in the provided context
    Grounding tests against the source
  • Complete enough for the user's task
    Completeness checks per request type
02

Safety, policy & domain

  • Safe + compliant + on-brand
    Safety, compliance, and tone evaluators
  • Aware of uncertainty
    Calibrated confidence judges
  • Aligned with domain-specific rules
    Domain-specific quality bar

Generic evals tell you if an answer looks reasonable — we tell you if it works for your product.

How it works

A calibration flow for teams that do not have a clean golden dataset yet.

Inputs

Bring task, docs, traces, and hypotheses

Start with the AI task, domain docs, selected traces, and a few hypotheses about what good looks like. No golden dataset is required upfront.

Argmin AI picks cases and analyzes evaluator mistakes
Cases

Argmin AI picks cases and analyzes evaluator mistakes

The platform finds normal, edge, and high-risk examples and surfaces where the evaluator disagrees with experts, so review time is spent on cases that actually move agreement.

Review

Experts review, confirm or correct calls

Experts review and correct evaluator calls Argmin AI drafts first — never from a blank page.

Experts review, confirm or correct calls
Corrections improve the evaluator and become the eval set
Calibrate

Corrections improve the evaluator and become the eval set

Every correction sharpens the evaluator and updates the calibrated eval set, quality rubric, score anchors, and calibration history.

Run

Test every AI change

Use the evaluator on prompt edits, model switches, RAG updates, routing changes, and agent releases.

Argmin AI gives your AI product the quality infrastructure it needs to move from prototype to production.

Key benefits & features

Map your task

Map your task

Analyze the assistant, users, workflows, and risks. Pinpoint where failure is most costly before scoring anything.

Calibrated judges

Calibrated judges

Task-specific LLM-as-a-judge prompts, calibrated against your team’s quality bar with reusable golden datasets.

Gate every release

Gate every release

Compare versions, catch regressions, and protect quality across prompts, models, RAG, and agents.

Decision history

Decision history

Every correction, calibration, and version comparison is retained — quality becomes inspectable infrastructure.

From existing AI assets to a calibrated quality layer

01

Define the quality rubric

Translate product expectations into structured dimensions: correctness, grounding, tone, domain.

02

Generate edge cases

Surface the cases manual testing misses — messy, conflicting, multi-step, policy-sensitive.

03

Build the golden dataset

A reusable dataset from real examples, expert cases, synthetic edges, and past failures.

04

Calibrate the judge

Task-specific LLM judges, calibrated against your team's quality bar with structured reasoning.

05

Regression test every release

Compare prompt, model, RAG, agent, and guardrail changes before they ship.

FAQ

No. Existing labels help, but they are not a precondition. Argmin AI starts from your task, domain docs, selected traces, and expert corrections during calibration.
Usually selected traces, representative outputs, product constraints, and domain docs. You decide what is shared. We can work under NDA and with tighter infrastructure constraints when needed.
No. Synthetic cases can expand coverage, but the calibration anchor should come from your real traces and your experts' corrections.
No. The evaluator drafts calls first, Argmin AI picks the cases that matter, and experts confirm or correct. Labeling becomes review, not a blank-page grind.
A calibrated eval set, quality rubric, runnable evaluator, core regression cases, and calibration history your team can reuse across AI changes.
Yes. The evaluator creates the quality bar first. After that, Argmin AI can optimize prompts, models, routing, retrieval, and agent architecture without flying blind.
