class Jais2Config(PreTrainedConfig):
|
|
r"""
|
|
This is the configuration class to store the configuration of a [`Jais2Model`]. It is used to instantiate a Jais2
|
|
model according to the specified arguments, defining the model architecture.
|
|
[inceptionai/Jais-2-8B-Chat](https://huggingface.co/inceptionai/Jais-2-8B-Chat).
|
|
|
|
Configuration objects inherit from [`PreTrainedConfig`] and can be used to control the model outputs. Read the
|
|
documentation from [`PreTrainedConfig`] for more information.
