+# mamba-retriever-do_not_open-regular_chunk
+
+This model is a fine-tuned version of [state-spaces/mamba2-130m](https://huggingface.co/state-spaces/mamba2-130m) for information retrieval tasks.
+
+## Model Details
+
+- **Base Model**: state-spaces/mamba2-130m
+- **Training Dataset**: lei-ucsd/do_not_open
+- **Configuration**: regular_chunk
+- **Task**: Binary classification for passage relevance in information retrieval
+
+## Training Details
+
+- **Dataset**: do_not_open
+- **Chunking Strategy**: regular_chunk
+- **Training Steps**: 1000 (checkpoint-1000)
+
+## Usage
+
+```python
+from transformers import AutoTokenizer, AutoModel
+import torch
+
+# Load model and tokenizer
+tokenizer = AutoTokenizer.from_pretrained("lei-ucsd/mamba-retriever-do_not_open-regular_chunk")
+model = AutoModel.from_pretrained("lei-ucsd/mamba-retriever-do_not_open-regular_chunk")
+
+# Example usage for information retrieval
+text = "Your query text here"
+inputs = tokenizer(text, return_tensors="pt", padding=True, truncation=True)
+
+with torch.no_grad():
+    outputs = model(**inputs)
+    # Use binary_logits for relevance scoring
+    binary_logits = outputs.binary_logits
+```
+
+## Model Architecture
+
+The model extends the base Mamba architecture with a binary classification head for passage relevance scoring.
+
+## Training Data
+
+This model was trained on the lei-ucsd/do_not_open dataset with regular_chunk chunking strategy.
+
+## Limitations
+
+This model is designed specifically for information retrieval tasks and may not perform well on other text classification tasks.
+
+## Citation
+
+If you use this model, please cite the original Mamba paper and the dataset used for training.
