+# haykgrigorian/TimeCapsuleLLM-v2-London-1800-1875: Llama-Architecture 1.2B Model 
+
+## Model Overview
+
+**v2** model, trained from scratch on 112GB of 1800-1875 london texts using a Llama-based Casual Language Model.
+
+| Detail | Value |
+| :--- | :--- |
+| **Model Architecture** | LlamaForCausalLM (Decoder-Only Transformer) |
+| **Parameter Count** | **~1.22B** |
+| **Training Type** | Trained **from Scratch** (Random Initialization) |
+| **Tokenizer** | Custom BPE, Vocab Size 32,000 |
+| **Sequence Length** | 2048 tokens |
+| **Attention Type** | Grouped Query Attention (GQA) |
+
+## Configuration Details
+
+This model is a custom size and configuration based on Llama:
+
+| Parameter | Value |
+| :--- | :--- |
+| **Number of Layers** | 22 |
+| **Hidden Size (d)** | 2048 |
+| **Intermediate Size ($\text{d}_{\text{ff}}$)** | 5504 |
+| **Attention Heads** | 16 (Query) / 8 (Key/Value) |
+| **Activation Function** | SiLU (`silu`) |
+| **Normalization** | RMS Norm (`rms_norm_eps`: 1e-06) |
+| **Position Embeddings** | Rotary Positional Embeddings (RoPE) |
+
+## Training Info
+
+This model was trained for 182,000 steps, about 0.5 epochs.
+
+Training Metrics:
+
+Final Training Loss: 3.3951
+
+Start Training Loss: 10.7932
+
+Training Steps: 182,000
+
+Epochs: 0.4997
+
+Gradient Norm Stability: Consistently stable between 0.50 and 0.60 in later stages.
+
+Training time: 117 hours 51 minutes
+
+### Cost 
+
+This model was trained on an H100 SXM from RunPod 
+
+Total: $340.97
+
+### How to Load and Run the Model
+
+Install all the files locally in a folder and run the test script. You will have to make some adjustments in the run script like updating the config/file path and test prompts
+
+### Test script
+
+A run file for testing and evaluating this model is available on the main project repository:
+
+* **Test Script Link:** [run_v2.py on GitHub](https://github.com/haykgrigo3/TimeCapsuleLLM/blob/main/london_1800_1875_v2/run_v2.py)
