## LEXA-8B
👉 **LEXA-8B**: LEXA: Legal Case Retrieval via Graph Contrastive Learning with Contextualised LLM Embeddings. More information is available in [**arXiv**](https://arxiv.org/abs/2405.11791) & [**GitHub**](https://github.com/yanran-tang/CaseGNN).
## Example Usage
```python
from transformers import AutoModel, AutoTokenizer
model = AutoModel.from_pretrained("AnnaStudy/LEXA-8B", torch_dtype="auto", device_map="auto")
tokenizer = AutoTokenizer.from_pretrained("AnnaStudy/LEXA-8B")
case_txt = "The following contains key components of a legal case. Legal facts..."
tokenized = tokenizer(case_txt, return_tensors='pt', padding=True, truncation=True, max_length=2048)
outputs = model(**tokenized)
case_embedding = outputs.last_hidden_state[:, -1]
```
## Base Model
ReaKase-8B is finetuned from **Qwen3-Embedding-8B**, which provides the underlying semantic representation capability.
