+# Merged-Llama-Adapters-317-320
+
+A merged LoRA adapter combining four fine-tuned adapters (317-320) for the Llama-3.1-8B language model.
+
+## Model Details
+
+- Base Model: meta-llama/Llama-3.1-8B-instruct
+- Adaptation Method: Merged LoRA
+- Source Adapters:
+  - https://huggingface.co/kevin009/llama317
+  - https://huggingface.co/kevin009/llama318
+  - https://huggingface.co/kevin009/llama319
+  - https://huggingface.co/kevin009/llama320
+
+## Merger Configuration
+
+### Source Adapters
+
+All source adapters share the following configuration:
+- Rank (r): 16
+- Alpha: 16
+- Target Modules:
+  - q_proj (Query projection)
+  - k_proj (Key projection)
+  - v_proj (Value projection)
+  - o_proj (Output projection)
+  - up_proj (Upsampling projection)
+  - down_proj (Downsampling projection)
+  - gate_proj (Gate projection)
+
+### Merger Details
+
+- Merger Method: Linear interpolation
+- Merger Weights: Equal weights (0.25) for each adapter
+- Combined Rank: 16 (maintained from source adapters)
+
+## Usage
+
+This merged adapter must be used with the base Llama-3.1-8B-instruct model.
+
+### Loading the Model
+
+```python
+from peft import PeftModel, PeftConfig
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+# Load base model
+base_model = AutoModelForCausalLM.from_pretrained("meta-llama/Llama-3.1-8B-instruct")
+tokenizer = AutoTokenizer.from_pretrained("meta-llama/Llama-3.1-8B-instruct")
+
+# Load merged LoRA adapter
+model = PeftModel.from_pretrained(base_model, "path_to_merged_adapter")
+```
+
+## Limitations and Biases
+
+- This merged adapter inherits limitations and biases from:
+  - The base Llama-3.1-8B-instruct model
+  - All four source adapters
+- The merging process may result in:
+  - Potential loss of specialized capabilities from individual adapters
+  - Averaged behavior across different adapter specializations
+  - Possible interference between adapter weights
+
+## Merging Process
+
+The adapters were merged using the following approach:
+1. Linear interpolation of adapter weights
+2. Equal weighting (0.25) applied to each source adapter
+3. Preservation of original LoRA rank and architecture
+
+### Method Used
+
+The adapters were merged using PEFT (Parameter-Efficient Fine-Tuning) library's weighted adapter combination feature. The process combines multiple LoRA adapters using linear interpolation with specified weights.
+
+### Step-by-Step Merging Process
+
+1. Load the base model and initial adapter:
+```python
+from peft import PeftModel, PeftConfig
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+MODEL_NAME = "meta-llama/Meta-Llama-3.1-8B-Instruct"
+model = AutoModelForCausalLM.from_pretrained(MODEL_NAME)
+tokenizer = AutoTokenizer.from_pretrained(MODEL_NAME)
+
+# Load first adapter as base
+peft_model = PeftModel.from_pretrained(model, "llama319", adapter_name="llama319")
+```
+
+2. Load additional adapters:
+```python
+# Load remaining adapters
+peft_model.load_adapter("llama320", adapter_name="llama320")
+peft_model.load_adapter("llama318", adapter_name="llama318")
+peft_model.load_adapter("llama317", adapter_name="llama317")
+```
+
+3. Configure and execute the merger:
+```python
+# Define adapters and their weights
+adapters = ["llama319", "llama320", "llama318", "llama317"]
+weights = [1.0, 1.0, 1.0, 1.0]  # Equal weights for all adapters
+
+# Merge adapters
+peft_model.add_weighted_adapter(
+    adapters, 
+    weights, 
+    "merge",
+    combination_type="ties",  # Using ties combination method
+    density=0.2              # Density parameter for merger
+)
+
+# Set active adapter to merged version
+peft_model.set_adapter("merge")
+
+# Save the merged adapter
+peft_model.save_pretrained("merged")
+```
+
+### Key Parameters
+
+- `combination_type="ties"`: Uses the TIES (Task Interference Edge Selection) method for combining adapters
+- `density=0.2`: Controls the sparsity of the merged weights
+- `weights=[1.0, 1.0, 1.0, 1.0]`: Equal weighting for all adapters (0.25 each after normalization)
+
+### Notes
+
+- The order of loading adapters may affect the final result
+- Equal weights were chosen to maintain balanced influence from each adapter
+- The merged adapter maintains the same architecture and rank as the original adapters
+- While this adapter merges multiple fine-tunes, each component was developed as part of independent research efforts to explore and language model capabilities as part of R&D process.
