# Data Designer Configuration

[DataDesignerConfig](#data_designer.config.data_designer_config.DataDesignerConfig) is the top-level configuration object passed to Data Designer. It declares the columns to generate and may include model configs, tool configs, seed settings, sampler constraints, processors, and profiler configs.

Prefer [DataDesignerConfigBuilder](config_builder.md#data_designer.config.config_builder.DataDesignerConfigBuilder) for programmatic construction. Direct [DataDesignerConfig](#data_designer.config.data_designer_config.DataDesignerConfig) instantiation is also supported.
