+# DgMind 20B: Advanced Reasoning & Expert Coding Assistant
+
+
+
+**DgMind 20B** is a state-of-the-art, fine-tuned large language model designed for high-level logical reasoning and professional-grade software development. Built upon the **GPT-OSS 20B** architecture, this model has been optimized using the Unsloth library to provide efficient yet powerful performance on consumer-grade hardware.
+
+
+
+## 👤 Identity & Developer
+
+* **Model Name:** DgMind
+
+* **Developer:** Erfan Mohamadnia
+
+* **Core Persona:** A specialized AI assistant that excels in complex coding tasks, architectural decisions, and deep logical analysis.
+
+
+
+## 📊 Training Details
+
+- **Base Model:** GPT-OSS 20B (Unsloth 4-bit optimized)
+
+- **Dataset:** [Code-290k-ShareGPT](https://huggingface.co/datasets/ajibawa-2023/Code-290k-ShareGPT)
+
+- **Technique:** LoRA (Low-Rank Adaptation)
+
+- **Optimization:** Fine-tuned specifically on responses to enhance conversational accuracy and identity injection.
+
+
+
+## 📈 Performance & Convergence
+
+The model demonstrates a stable decrease in training loss, ensuring precise instruction following and a minimized hallucination rate in coding contexts.

+
+
+
+## 💬 Prompt Template (Chat Format)
+
+DgMind uses the following message structure to maintain context and role separation:
+
+
+
+```text
+
+{% for message in messages %}{{ '<|start|>' + message['role'] + '<|message|>' + message['content'] + '<|end|>' }}{% endfor %}{% if add_generation_prompt %}{{ '<|start|>assistant<|message|>' }}{% endif %}
+
+
+
+```
+
+
+
+### Example:
+
+
+
+```text
+
+<|start|>user<|message|>Write a Python script for a custom API gateway.<|end|>
+
+<|start|>assistant<|message|>
+
+
+
+```
+
+
+
+## 🛠 Deployment & Usage
+
+
+
+### Local Execution via Ollama
+
+
+
+1. Download the `.gguf` file.
+
+2. Create a file named `Modelfile`:
+
+```dockerfile
+
+FROM "./DgMind-20B.Q4_K_M.gguf"
+
+PARAMETER temperature 0.7
+
+SYSTEM """You are DgMind, a helpful AI assistant developed by Erfan Mohamadnia. You specialize in advanced reasoning and expert-level coding."""
+
+
+
+```
+
+
+
+
+
+3. Run: `ollama create DgMind -f Modelfile` then `ollama run DgMind`.
+
+
+
+### Server Integration (llama.cpp)
+
+
+
+Run the internal API server:
+
+
+
+```bash
+
+./llama-server -m DgMind-20B.Q4_K_M.gguf --host 0.0.0.0 --port 8080 --n-gpu-layers 62
+
+
+
+```
