-OpenLLM Training Space - Main Application
+OpenLLM Training Space Application - Fixed with Uploaded Modules
 
-This is the main entry point for the Hugging Face Space.
-It provides a web interface for running OpenLLM training with authentication.
+This version imports OpenLLM modules from the uploaded files in the HF Space:
+- Imports model.py and data_loader.py that were uploaded to the Space
+- Uses OpenLLM's actual custom model architecture
+- Compatible with OpenLLM's implementation
+
+This application provides a complete training interface for OpenLLM models on Hugging Face Spaces.
+It uses OpenLLM's custom GPTModel architecture instead of Hugging Face Transformers,
+ensuring compatibility with the actual OpenLLM implementation.
+
+Key Features:
+- Real model training using OpenLLM's custom architecture
+- SentencePiece tokenization for OpenLLM models
+- Complete training pipeline with progress monitoring
+- Automatic model saving and uploading to Hugging Face Hub
+- Gradio 4.44.1 compatible user interface
+
+Technical Architecture:
+- Uses OpenLLM's GPTModel class (not Hugging Face Transformers)
+- Imports custom modules from uploaded files in the Space
+- Uses sentencepiece.SentencePieceProcessor() for tokenization
+- Implements OpenLLM's training loop and optimization strategy
+- Saves checkpoints in OpenLLM's format

+        - Separates parameters for different weight decay rates
+        - Uses gradient clipping for stability
         
-        1. **Environment Check**: Verify Space configuration and authentication

+        ### **Step 1: Configure Parameters**
+        - **Model Size**: Select the base model to train from (small, medium, large)
+        - **Max Steps**: Number of training iterations (100-10,000)
+        - **Learning Rate**: Training rate (0.00001-0.001)
+        - **Batch Size**: Samples per training batch (1-16)
+        
+        ### **Step 2: Start Training**
+        - Click "Start Training" to begin the actual training process
+        - Uses OpenLLM's custom GPTModel class from uploaded files
+        - Uses sentencepiece.SentencePieceProcessor() for tokenization
+        - Compatible with OpenLLM's actual implementation
+

+        - The final model will be uploaded to Hugging Face Hub
+        
+        ### **Step 4: Access Results**
+        - Trained models are automatically pushed to: `lemms/openllm-{size}-extended-8k`
+        - Check the model repository for your trained model
+        - Use the model for inference or further training
