Defining Custom Metrics for Precise AI Function Evaluation with Evals.do

In the fast-evolving world of AI, building powerful functions, workflows, and agents is only half the battle. The true differentiator lies in understanding how well they perform. This isn't just about whether an AI completes a task, but if it does so accurately, efficiently, and in line with your specific quality standards. This is where Evals.do, the comprehensive AI component evaluation platform, becomes indispensable.

Why Standard Metrics Aren't Enough for AI

While general performance metrics offer a baseline, AI applications often demand a more nuanced approach. A customer support agent might accurately answer a question but use an inappropriate tone. A medical diagnostic AI might be 99% accurate, but that 1% error could be catastrophic without further evaluation on specific edge cases. Your unique business needs dictate unique performance criteria.

This is precisely why Evals.do empowers you to go beyond generic evaluations and define custom metrics tailored to your AI functions.

The Power of Custom Metrics with Evals.do

Evals.do isn't a black box. It's a transparent, flexible platform that allows you to specify exactly what "good" looks like for your AI. Let's look at how you can apply this to an AI function, using a customer support agent as an example:

import { Evaluation } from 'evals.do';

const agentEvaluation = new Evaluation({
  name: 'Customer Support Agent Evaluation',
  description: 'Evaluate the performance of customer support agent responses',
  target: 'customer-support-agent',
  metrics: [
    {
      name: 'accuracy',
      description: 'Correctness of information provided',
      scale: [0, 5],
      threshold: 4.0
    },
    {
      name: 'helpfulness',
      description: 'How well the response addresses the customer need',
      scale: [0, 5],
      threshold: 4.2
    },
    {
      name: 'tone',
      description: 'Appropriateness of language and tone',
      scale: [0, 5],
      threshold: 4.5
    }
  ],
  dataset: 'customer-support-queries',
  evaluators: ['human-review', 'automated-metrics']
});

In this example, we're not just checking if the agent provides an answer. We're meticulously evaluating:

• accuracy: Is the information factually correct? (Perhaps on a scale of 0-5, with 5 being perfectly correct).
• helpfulness: Does the response truly address the customer's underlying problem? This goes beyond a simple answer to effective problem-solving.
• tone: Is the agent communicating with empathy, professionalism, and according to brand guidelines? This is crucial for customer satisfaction.

For each custom metric, you can define:

• name: A unique identifier for your metric.
• description: A clear explanation of what the metric measures.
• scale: The range of possible scores (e.g., [0, 1] for binary, [0, 5] for a qualitative scale).
• threshold: The minimum acceptable score for that metric, allowing you to set clear quality benchmarks.

How Evals.do Works for Your AI Functions

Evals.do streamlines the entire evaluation process:

1. Define Custom Criteria: As shown above, you set the precise metrics that matter most for your AI function.
2. Collect Data: Evals.do helps you gather data from your AI components' interactions and outputs.
3. Process with Evaluators: Leverage both human reviewers and automated metrics, or even other AI models, to score against your defined criteria.
4. Generate Reports: Receive comprehensive performance reports that highlight successes, identify areas for improvement, and ensure your AI meets your quality standards.

Whether you're evaluating standalone AI functions, complex workflows, or sophisticated agents, Evals.do provides the flexibility and depth needed for truly effective AI quality assurance.
