+# Ollama Model Files Collection
+
+This repository contains custom Ollama model configurations optimized for various tasks, particularly git commit message generation and general AI assistance.
+
+## Available Models
+
+### 1. **commit-msg-ernie** - ERNIE-4.5 Commit Message Generator
+- **Base Model**: ERNIE-4.5-0.3B (Q4_K_M quantization)
+- **Purpose**: Generates conventional commit messages from git diffs
+- **Context Window**: 4096 tokens
+- **Optimizations**: Temperature 0.4, Top-P 0.9 for consistent output
+
+### 2. **commit-msg-gemma3** - Gemma 3 Commit Message Generator  
+- **Base Model**: Gemma 3 1B
+- **Purpose**: Alternative commit message generator using Google's Gemma 3
+- **Context Window**: 4096 tokens
+- **Optimizations**: Similar parameters to ERNIE variant for consistency
+
+### 3. **ernie-fixed** - ERNIE-4.5 General Purpose
+- **Base Model**: ERNIE-4.5-21B (IQ4_XS quantization)
+- **Purpose**: General-purpose conversational AI with improved chat template
+- **Features**: Uses ChatML-style template with proper token handling
+
+## Prerequisites
+
+Before installing these models, ensure you have:
+
+- [Ollama](https://ollama.ai/) installed on your system
+- Sufficient disk space (models range from 1-15GB depending on quantization)
+- Internet connection for downloading base models
+
+### Install Ollama
+
+**Linux/macOS:**
+```bash
+curl -fsSL https://ollama.ai/install.sh | sh
+```
+
+**Windows:**
+Download from [ollama.ai](https://ollama.ai/download)
+
+## Installation Instructions
+
+### Method 1: Direct Installation from Repository
+
+1. **Clone the repository:**
+```bash
+git clone https://gitea.puchstein.bayern/mpuchstein/Ollama-Modelfiles.git
+cd Ollama-Modelfiles
+```
+
+2. **Install individual models:**
+
+**For commit message generation with ERNIE:**
+```bash
+cd commit-msg-ernie
+ollama create commit-msg-ernie -f Modelfile
+```
+
+**For commit message generation with Gemma 3:**
+```bash
+cd commit-msg-gemma3
+ollama create commit-msg-gemma3 -f Modelfile
+```
+
+**For general purpose ERNIE chat:**
+```bash
+cd ernie-fixed
+ollama create ernie-fixed -f Modelfile
+```
+
+3. **Verify installation:**
+```bash
+ollama list
+```
+
+### Method 2: Individual Model Installation
+
+You can install specific models without cloning the entire repository:
+
+**Download specific Modelfile:**
+```bash
+# Example for commit-msg-ernie
+wget https://gitea.puchstein.bayern/mpuchstein/Ollama-Modelfiles/raw/branch/main/commit-msg-ernie/Modelfile
+ollama create commit-msg-ernie -f Modelfile
+```
+
+## Usage Examples
+
+### Commit Message Generation
+
+**Using ERNIE variant:**
+```bash
+# Generate commit message from git diff
+git diff --cached | ollama run commit-msg-ernie
+```
+
+**Using Gemma 3 variant:**
+```bash
+# Alternative commit message generator
+git diff --cached | ollama run commit-msg-gemma3
+```
+
+### General Chat (ERNIE-Fixed)
+
+```bash
+# Start interactive chat session
+ollama run ernie-fixed
+
+# Or single query
+echo "Explain quantum computing" | ollama run ernie-fixed
+```
+
+## Integration with Git Workflow
+
+### Automated Commit Messages
+
+Create a git alias for automated commit message generation:
+
+```bash
+# Add to your ~/.gitconfig
+git config --global alias.aicommit '!f() { git add .; msg=$(git diff --cached | ollama run commit-msg-ernie); git commit -m "$msg"; }; f'
+```
+
+**Usage:**
+```bash
+# Stage changes and generate commit automatically
+git aicommit
+```
+
+### Git Hook Integration
+
+Create a `prepare-commit-msg` hook:
+
+```bash
+#!/bin/sh
+# .git/hooks/prepare-commit-msg
+
+if [ "$2" = "" ]; then
+    # Only generate for manual commits (not merges, etc.)
+    COMMIT_MSG=$(git diff --cached | ollama run commit-msg-ernie)
+    if [ -n "$COMMIT_MSG" ]; then
+        echo "$COMMIT_MSG" > "$1"
+    fi
+fi
+```
+
+Make it executable:
+```bash
+chmod +x .git/hooks/prepare-commit-msg
+```
+
+## Model Specifications
+
+| Model | Base Model | Size | Context | Temperature | Use Case |
+|-------|------------|------|---------|-------------|----------|
+| commit-msg-ernie | ERNIE-4.5-0.3B | ~300MB | 4096 | 0.4 | Git commits |
+| commit-msg-gemma3 | Gemma 3 1B | ~1GB | 4096 | 0.4 | Git commits |
+| ernie-fixed | ERNIE-4.5-21B | ~15GB | Default | Default | General chat |
+
+## Customization
+
+### Modifying System Prompts
+
+To customize the behavior, edit the `SYSTEM` section in any Modelfile:
+
+```dockerfile
+SYSTEM """
+Your custom system prompt here...
+"""
+```
+
+Then recreate the model:
+```bash
+ollama create your-model-name -f Modelfile
+```
+
+### Parameter Tuning
+
+Adjust model parameters for different behaviors:
+
+- **Temperature**: Lower (0.1-0.4) for consistency, higher (0.7-1.0) for creativity
+- **Top-P**: Controls nucleus sampling (0.9 recommended)
+- **Context Length**: Increase for larger diffs/inputs
+
+## Troubleshooting
+
+### Common Issues
+
+**Model download fails:**
+- Check internet connection
+- Verify Hugging Face model availability
+- Try downloading base model separately: `ollama pull gemma3:1b`
+
+**Out of memory errors:**
+- Use smaller quantizations (Q4_K_M instead of F16)
+- Reduce context window
+- Close other applications
+
+**Poor commit message quality:**
+- Ensure git diff has meaningful changes
+- Check that changes are staged (`git add`)
+- Consider adjusting temperature parameter
+
+### Performance Tips
+
+1. **GPU Acceleration**: Ollama automatically uses GPU if available
+2. **Model Caching**: Models stay loaded in memory for faster subsequent calls
+3. **Batch Processing**: Process multiple diffs efficiently by keeping model loaded
+
