Domino Model Monitor vs Opik

Domino Model Monitor evaluates production machine-learning models and alerts when degradation warrants expert review. It monitors data drift and model quality from a central dashboard showing status, summaries, customized alerts, and monitoring results. Automated prediction-data pipelines and metric generation support ongoing checks. When remediation is needed, teams can recreate a model’s development environment, retrain with production data, and redeploy a version. Models built in Python, R, SAS, MATLAB, TensorFlow, or DataRobot can be registered. The Elastic Monitoring Engine is designed to scale and ingest data from Amazon S3 and Hadoop-compatible storage, including Azure Blob Storage, Azure Data Lake, Google Cloud Storage, and HDFS. Domino supports API, web, and self-hosted use, including cloud VPCs, on-premises systems, and air-gapped environments. Pricing is on request, with Premium, Domino Cloud, and Enterprise plans listed.

Opik helps teams building applications or agents that call an LLM log actions and evaluate behavior across development, testing, and production. It captures and visualizes traces, supports annotation, and provides audit logs. Its evaluation tools include more than 30 metrics for outcomes such as answer relevance, context precision, task completion, and hallucination. In production, Opik can evaluate traces in real time, alert when criteria fail, and track token use and model costs. Test Suites offer pass/fail assertions, an Agent Playground supports end-to-end tests, and a Prompt Optimizer provides six algorithms. Core observability and evaluation features are available as open-source code for local use. Opik includes a REST API and Python client, with Python and TypeScript SDKs listed, and integrations with more than 40 frameworks, model providers, and gateways. Free Cloud allows up to 10 team members, 25,000 spans per month, and 60-day retention. Pro Cloud costs $19 a month and lists up to 50 team members and 100,000 spans monthly.
