class easydel.modules.qwen3.__init__.Qwen3ForCausalLM(*args: Any, **kwargs: Any)

Bases: EasyDeLBaseModule

Qwen3 model with a Causal Language Modeling head.

This model consists of the base Qwen3 transformer (Qwen3Model) followed by a linear layer (lm_head) that projects the transformer’s output hidden states to the vocabulary size, producing logits for next token prediction. Optionally, the input token embeddings can be tied to the output projection layer.

class easydel.modules.qwen3.__init__.Qwen3ForSequenceClassification(*args: Any, **kwargs: Any)

Bases: EasyDeLBaseModule

Qwen3 model with a Sequence Classification head.

This model consists of the base Qwen3 transformer (Qwen3Model) followed by a linear layer (score) that projects the transformer’s output hidden states (typically the hidden state of the last token or a pooled representation) to the number of classes for classification.
