MLDB Review

mldb.ai →

MLDB is an open-source machine learning database from 2017 that lets developers store, query, and run ML models via a SQL-like interface.

General-Purpose Assistants

Verdict

MLDB was an ambitious open-source project that treated machine learning as a database problem, exposing models and datasets through a REST API and SQL-style queries. Development appears to have halted around 2017 and the project is effectively inactive. It is not an LLM or AI chat tool, making its current categorization incorrect, and its defunct status makes it unsuitable for an active AI tools directory.
