AI's Hardest Problem is Evaluation, Not Intelligence

EvalMate helps you define what "correct" means for your agents, then automates evaluation so you can ship with confidence.

The Challenge

Building AI agents is hard. Evaluating them is harder.

01

Define Correctness

Every agent needs its own definition of quality. Domain experts carry it in their heads but struggle to write it down. Different team members have different standards. Without a shared definition, you're guessing.

  • Needs access to domain experts
  • Hard to articulate what "good" looks like
  • Divergent mental models across teams
02

Evaluate Correctness

Manual review doesn't scale past a few hundred examples. Generic LLM judges don't match your quality bar. Custom judges are expensive to build and maintain.

  • Impossible to scale with human annotators
  • Off-the-shelf LLM judges don't align with your team
  • Aligned judges are costly to operate at scale
How EvalMate Works

From 100 examples to automated evaluation at scale

01

Define your quality bar

Tell EvalMate what good looks like. Share a handful of examples (~100 preferences) and EvalMate's agentic workflow proposes, critiques, and refines a rubric that captures your team's definition of correctness.

Input ~100 human preferences
Output A structured rubric your whole team can use
02

Build an aligned judge

EvalMate fine-tunes an LLM judge that scores responses the way your team would. Using smart sampling, it needs only ~1,000 human-reviewed examples to match your annotators at 10x lower cost.

Input ~1,000 optimally-chosen annotations
Result 10x cost reduction vs. human review
03

Scale evaluation automatically

EvalMate distills your judge into a compact reward model (~8B parameters) that runs on your infrastructure. Evaluate every response, continuously, at 100x lower cost than human review.

Input ~10,000 judge annotations
Result 100x cost reduction, runs on-prem
The Rubric

Your single source of truth for quality

The rubric is a structured checklist of evaluation dimensions, each with a weight and scale. It becomes the shared language between your team, your LLM judge, and your reward model. Everyone evaluates against the same criteria.

  • Consistent evaluation across human reviewers, LLM judges, and automated models
  • Evolves with your product as requirements change
  • Captures nuance: not just pass/fail, but weighted dimensions like helpfulness, correctness, and coherence
Example Rubric
Helpfulness
0.8x
Correctness
0.6x
Coherence
0.4x
Conciseness
0.3x
Verbosity
-0.2x
What This Unlocks

Once you can evaluate reliably, everything else follows

Fine-tune on your own data

Use evaluation signals to fine-tune smaller models on your proprietary data, improving quality while reducing cost. Your reward model provides the training signal, no additional annotation needed.

Route prompts to the right model

Train a lightweight classifier that sends each request to the best model for the job. Simple queries go to fast, affordable models. Complex ones go to frontier models. Cut costs without losing quality.
