# FSI_Edge-{model_size}

**Novel DNA Helix Memory Architecture** — built from scratch.

A production-grade coding specialist designed for on-device deployment on Android.

## Architecture Features

- **DNA Helix Memory**: Unlimited context window via curved memory structure
- **Hierarchical Code Attention**: 3-tier attention (local → structural → global sparse)
- **Execution-Augmented FFN**: Two-stream FFN with execution trace injection
- **RoPE with Structural Bias**: Position encoding aware of AST depth
- **Mixture-of-Depths**: Per-token dynamic layer skipping

## Training

- 4+ trillion tokens of curated code + NLP data
- Multi-stage curriculum: pretraining → SFT → GRPO RL with execution feedback
- Novel training techniques from frontier model research

## Deployment

- **Android compatible** (4-bit quantized: ~500MB)
- **GGUF format** for llama.cpp inference
- Runs on Snapdragon 8 Gen 3 NPU

## Quick Start

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("{repo_id}")
tokenizer = AutoTokenizer.from_pretrained("{repo_id}")

prompt = "def fibonacci(n):"
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=128)
print(tokenizer.decode(outputs[0]))
```
