!!! abstract "Usage Documentation"
[Models](/docs/api-reference/autogen/concepts/models)

A base class for creating Pydantic models.<br />Attributes: <br />    **class\_vars**: The names of the class variables defined on the model.<br />    **private\_attributes**: Metadata about the private attributes of the model.<br />    **signature**: The synthesized `__init__` \[`Signature`]\[inspect.Signature] of the model.<br />    **pydantic\_complete**: Whether model building is completed, or if there are still undefined fields.<br />    **pydantic\_core\_schema**: The core schema of the model.<br />    **pydantic\_custom\_init**: Whether the model has a custom `__init__` function.<br />    **pydantic\_decorators**: Metadata containing the decorators defined on the model.<br />        This replaces `Model.__validators__` and `Model.__root_validators__` from Pydantic V1.<br />    **pydantic\_generic\_metadata**: Metadata for generic models; contains data used for a similar purpose to
**args**, **origin**, **parameters** in typing-module generics. May eventually be replaced by these.<br />    **pydantic\_parent\_namespace**: Parent namespace of the model, used for automatic rebuilding of models.<br />    **pydantic\_post\_init**: The name of the post-init method for the model, if defined.<br />    **pydantic\_root\_model**: Whether the model is a \[`RootModel`]\[pydantic.root\_model.RootModel].<br />    **pydantic\_serializer**: The `pydantic-core` `SchemaSerializer` used to dump instances of the model.<br />    **pydantic\_validator**: The `pydantic-core` `SchemaValidator` used to validate instances of the model.<br />    **pydantic\_fields**: A dictionary of field names and their corresponding \[`FieldInfo`]\[pydantic.fields.FieldInfo] objects.<br />    **pydantic\_computed\_fields**: A dictionary of computed field names and their corresponding \[`ComputedFieldInfo`]\[pydantic.fields.ComputedFieldInfo] objects.<br />    **pydantic\_extra**: A dictionary containing extra values, if \[`extra`]\[pydantic.config.ConfigDict.extra]
is set to `'allow'`.<br />    **pydantic\_fields\_set**: The names of fields explicitly set during instantiation.<br />    **pydantic\_private**: Values of private attributes set on the model instance.<br />Base message class
