Opik integration adapter for Metrics Computation Engine

MCE Opik Adapter

A Python adapter library that integrates Opik metrics as third-party plugins for the Metric Computation Engine (MCE). This adapter enables seamless use of Opik's LLM evaluation metrics within the MCE framework for evaluating agentic applications.

Installation

Install via MCE extras:

pip install "metrics-computation-engine[opik]"

Prerequisites

• Metric Computation Engine (MCE) installed
• Agentic applications instrumented with AGNTCY's observe SDK

Supported Opik Metrics

The following Opik metrics are supported by this adapter (use with the opik. prefix in service payloads):

Metric Name	Description
Hallucination	Evaluates whether the model response contains hallucinations
Sentiment	Measures the sentiment of a model response

For requests to support additional Opik metrics, please file an issue in our repo: agntcy/telemetry-hub.

Usage

Basic Usage

import asyncio
from mce_opik_adapter.adapter import OpikMetricAdapter
from metrics_computation_engine.models.requests import LLMJudgeConfig
from metrics_computation_engine.registry import MetricRegistry

# Initialize LLM configuration
llm_config = LLMJudgeConfig(
    LLM_BASE_MODEL_URL="https://api.openai.com/v1",
    LLM_MODEL_NAME="gpt-4o",
    LLM_API_KEY="your-api-key-here"
)

# Create registry and register Opik metrics
registry = MetricRegistry()

# Method 1: Direct registration with metric name
registry.register_metric(OpikMetricAdapter, "Hallucination")

# Method 2: Using get_metric_class helper with prefix
from metrics_computation_engine.util import get_metric_class
metric, metric_name = get_metric_class("opik.Hallucination")
registry.register_metric(metric, metric_name)

Using with MCE REST API

When using the MCE as a service, include Opik metrics in your API request:

{
  "metrics": [
    "opik.Hallucination",
    "opik.Sentiment"
  ],
  "llm_judge_config": {
    "LLM_API_KEY": "your-api-key",
    "LLM_MODEL_NAME": "gpt-4o",
    "LLM_BASE_MODEL_URL": "https://api.openai.com/v1"
  },
  "data_fetching_infos": {
    "batch_config": {
      "time_range": { "start": "2024-01-01T00:00:00Z", "end": "2024-12-31T23:59:59Z" }
    },
    "session_ids": []
  }
}
