What is Deepchecks?
Deepchecks is a validation and testing platform for machine learning models, data, and large language model applications, used by data scientists and ML engineers to catch issues from research through production.
At its core is an open-source Python package built around three concepts: checks, the building blocks that probe a specific aspect of data or a model; conditions, which add pass, fail, or warning outcomes to checks; and suites, ordered collections of checks and conditions that can be run together.
With these, teams can examine data integrity, assess distributions, validate train and test splits, compare models, and evaluate performance across the entire development cycle, surfacing problems like data drift, leakage, and degraded accuracy before they reach users.
Alongside the open-source library, Deepchecks offers an enterprise-grade LLM evaluation, observability, and monitoring product that provides visibility and control over generative AI systems in production, helping teams measure quality, detect regressions, and build trust in deployed models.
Typical use cases include continuous validation in ML pipelines, pre-deployment model checks, and ongoing monitoring of both traditional models and LLM agents. Strengths include the free and extensible open-source foundation, broad coverage of data and model checks, and a clear path from experimentation to production monitoring.
Limitations include a learning curve for teams new to ML testing concepts and the fact that advanced observability and collaboration features sit in the paid enterprise offering. Deepchecks combines a free open-source package with paid enterprise plans. Pricing changes often, so check the official site for current plans.
