# mythos_full : GGUF

This model was finetuned on the **Opus 4.7 dataset** (using ~1,40,000 high-quality samples) and converted to GGUF format.

**Credit**: Finetuned efficiently using [Unsloth](https://github.com/unslothai/unsloth).

**Example usage**:
- For text only LLMs:    `llama-cli -hf Shadow0482/mythos_full --jinja`
- For multimodal models: `llama-mtmd-cli -hf Shadow0482/mythos_full --jinja`

## Available Model files:
- `gemma-4-E2B-it-Uncensored-MAX.F16.gguf`
- `gemma-4-E2B-it-Uncensored-MAX.BF16-mmproj.gguf`

## Training Details

The model was fine-tuned on the **Opus 4.7 dataset** using approximately 40,000 samples. This dataset consists of high-quality instruction-response pairs (including advanced Chain-of-Thought reasoning traces, typically generated by Claude Opus 4.7 for superior reasoning and instruction-following capabilities).

### Detailed Training Steps:

1. **Dataset Preparation**:
   - Acquired/gathered the Opus 4.7 dataset containing ~40,000 high-quality samples.
   - Performed data cleaning, deduplication, and quality filtering to remove low-quality or redundant entries.
   - Formatted all samples into the appropriate instruction-tuning/chat template (compatible with Gemma models, using system/user/assistant roles and multimodal support where applicable).
   - Split the dataset into training and validation sets (typically 95/5 ratio).

2. **Environment Setup**:
   - Set up a training environment with Hugging Face Transformers, TRL, PEFT, and the necessary GPU resources (multi-GPU setup with high VRAM).
   - Loaded the base model in 4-bit quantization for memory efficiency during training.

3. **Model Configuration**:
   - Applied LoRA (Low-Rank Adaptation) adapters for parameter-efficient fine-tuning on the base Gemma-4-E2B-it model.
   - Configured the training pipeline for supervised fine-tuning (SFT), including proper handling of vision-language components (text + image projector).

4. **Training**:
   - Ran supervised fine-tuning on the 40,000 prepared samples.
   - Monitored training loss, validation metrics, and adjusted hyperparameters as needed (learning rate, batch size, number of epochs, warmup steps, LoRA rank/alpha, etc.).
   - Completed the full training run to produce the fine-tuned "mythos_full" model while preserving the uncensored behavior of the base.

5. **Post-Training Processing**:
   - Merged the LoRA adapters back into the base model weights.
   - Saved the resulting fine-tuned model in Hugging Face format.

6. **GGUF Conversion & Quantization**:
   - Converted the fine-tuned model to GGUF format using the official llama.cpp tools.
   - Generated the main model file in full F16 precision.
   - Converted the multimodal projector (mmproj) to `BF16-mmproj.gguf` format.
   - Verified model integrity and basic functionality post-conversion.

This process produced a high-performance, uncensored vision-language model optimized for both text-only and multimodal inference with llama.cpp.
