+# Sparse Autoencoders for Qwen/Qwen2.5-7B-Instruct
+
+This repository contains 1 Sparse Autoencoder(s) (SAE) trained using [SAELens](https://github.com/jbloomAus/SAELens).
+
+## Model Details
+
+| Property | Value |
+|----------|-------|
+| **Base Model** | `Qwen/Qwen2.5-7B-Instruct` |
+| **Architecture** | `standard` |
+| **Input Dimension** | 3584 |
+| **SAE Dimension** | 16384 |
+| **Training Dataset** | `TQRG/DeltaSecommits_qwen-2.5-7b-instruct_tokenized_v2_vulnerable` |
+
+## Available Hook Points
+
+| Hook Point |
+|------------|
+| `blocks.11.hook_resid_post` |
+
+## Usage
+
+```python
+from sae_lens import SAE
+
+# Load an SAE for a specific hook point
+sae, cfg_dict, sparsity = SAE.from_pretrained(
+    release="rufimelo/vulnerable_code_qwen_coder_standard_16384_50M",
+    sae_id="blocks.11.hook_resid_post"  # Choose from available hook points above
+)
+
+# Use with TransformerLens
+from transformer_lens import HookedTransformer
+
+model = HookedTransformer.from_pretrained("Qwen/Qwen2.5-7B-Instruct")
+
+# Get activations and encode
+_, cache = model.run_with_cache("your text here")
+activations = cache["blocks.11.hook_resid_post"]
+features = sae.encode(activations)
+```
