# SDory-DoRA: Sparse Latent-Recurrent Decomposed Architecture

**SDory-DoRA** is a next-generation parameter-efficient architecture that fuses **NVIDIA Dory's Latent-Recurrent Looping Core** with **Weight-Decomposed Low-Rank Adaptation (DoRA)**, **Top-5% Sparsity Filtering**, and **Orthogonal Anti-Forgetting Constraints**.

Designed specifically for consumer hardware (e.g., laptop GPUs with 8 GB VRAM), SDory-DoRA allows training and deploying frontier-grade reasoning models using **only ~2.7 GB of GPU VRAM** and producing **micro-skill checkpoints under 4 Megabytes**.

## Quickstart Installation

Install the library directly using `pip`:

```bash
git clone https://github.com/vantix-ai/sdory-dora.git
cd sdory-dora
pip install -e .
```

---

## Python Usage Example

### 1. Training a Custom Skill in 3 Lines of Code

```python
from transformers import AutoTokenizer
from sdory_dora import SDoryDoRAConfig, SDoryDoRAForCausalLM, SDoryDoRATrainer

# Initialize architecture configuration
config = SDoryDoRAConfig(
    default_recurrent_loops=2,  # 2 Thinking loops
    dora_rank=8,
    sparsity_ratio=0.05        # Top 5% expert neurons
)

# Load model (automatically configures 4-bit NF4 base + recurrent core)
model = SDoryDoRAForCausalLM(config=config)
tokenizer = AutoTokenizer.from_pretrained(config.model_name_or_path, trust_remote_code=True)

# Train on any JSONL dataset
trainer = SDoryDoRATrainer(model=model, tokenizer=tokenizer, batch_size=1)
trainer.train(
    data_path="my_dataset.jsonl",
    epochs=2,
    output_dir="checkpoints/my_new_skill"
)
# Result: Saves a 3.37 MB micro-adapter!
```

---

### 2. High-Performance Inference with Elastic Thinking Depth

```python
from transformers import AutoTokenizer
from sdory_dora import SDoryDoRAConfig, SDoryDoRAForCausalLM, SDoryDoRAGenerator

config = SDoryDoRAConfig(default_recurrent_loops=2)
model = SDoryDoRAForCausalLM(config=config)

# Hot-swap the trained 3.37 MB micro-adapter in < 0.1s:
model.load_micro_adapter("checkpoints/my_new_skill/trained_sdory_dora_skill.pt")
tokenizer = AutoTokenizer.from_pretrained(config.model_name_or_path, trust_remote_code=True)

generator = SDoryDoRAGenerator(model=model, tokenizer=tokenizer)

# Fast Mode (1 Loop) vs Deep Reasoning Mode (3 Loops)
response = generator.generate(
    prompt="Explain Kerberos Golden Ticket attack and prevention.",
    loops=3,  # Elastic Thinking Mode
    max_new_tokens=128
)

print(response["generated_text"])
print("Grounding Confidence:", response["confidence"])
```

---

## Command-Line Interface (CLI)

Train or chat directly from your terminal:

```bash
# 1. Train on your data
sdory-train --data "dataset.jsonl" --epochs 2 --loops 2 --output_dir "checkpoints/my_skill"

# 2. Interactive chat with elastic thinking loops
sdory-chat --adapter "checkpoints/my_skill/trained_sdory_dora_skill.pt" --loops 2
```

## Hardware Safety & Compatibility

- **Validated Hardware:** NVIDIA GeForce RTX 5050 Laptop GPU (8 GB VRAM), 16 GB RAM.
- **Operating System:** Windows 11 / Linux.
- **VRAM Ceiling:** Hard-capped at 80% allocation fraction to guarantee dedicated OS display headroom.
- **RAM Optimization:** Direct-to-VRAM disk streaming with Windows `EmptyWorkingSet()` cache purging.
