# FrankenMoE — Qwen2.5-1.5B Expert Models 🇹🇭

**3 specialized LoRA fine-tuned experts** — coding, math, and chat — built from Qwen2.5-1.5B-Instruct with 13,000 curated training samples.

> 🛑 MoE merge skipped (mergekit does not support Qwen2 MoE architecture).  
> ✅ Each expert is independently usable as LoRA adapter or GGUF.

## 📦 What's Inside

| Expert | Domain | LoRA | GGUF (Q4_K_M) | Train Loss | Eval Loss |
|--------|--------|------|---------------|------------|-----------|
| **coding** | Python/Algorithm/SWE | 71 MB | 941 MB | 1.03 | - |
| **math** | Mathematics/Proofs | 70 MB | 941 MB | 1.18 | - |
| **chat** | Instruction Following | 74 MB | 941 MB | 1.23 | 1.27 |

## 🚀 Quick Start

### Option 1: LoRA with PEFT (Python)

```python
from peft import PeftModel
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

base = "Qwen/Qwen2.5-1.5B-Instruct"
model = AutoModelForCausalLM.from_pretrained(base, torch_dtype=torch.bfloat16)
model = PeftModel.from_pretrained(model, "hotdogs/frankenmoe", subfolder="coding")
tokenizer = AutoTokenizer.from_pretrained("hotdogs/frankenmoe", subfolder="coding")

prompt = "Write a Python function to reverse a linked list"
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=256)
print(tokenizer.decode(outputs[0]))
```

### Option 2: GGUF with llama.cpp

```bash
# Download
wget https://huggingface.co/hotdogs/frankenmoe/resolve/main/coding/frankenmoe_coding-Q4_K_M.gguf

# Run
llama.cpp/build/bin/llama-cli \
  -m frankenmoe_coding-Q4_K_M.gguf \
  -p "Write a Python function to reverse a linked list" \
  -n 256
```

### Option 3: Ollama Modelfile

```dockerfile
FROM ./frankenmoe_coding-Q4_K_M.gguf
SYSTEM "You are a coding expert specialized in Python, algorithms, and software engineering."
```

## 📊 Training Logs

| Expert | Steps | Train Loss | Final LR | Time |
|--------|-------|-----------|----------|------|
| coding | 564 | 1.03 | - | ~15 min |

## ⚠️ Known Limitations

- **No MoE routing** — experts are independent models, not a single MoE
- **Small base model** (1.5B) — good for experimentation, limited for production
- **Qwen2 architecture** — not compatible with mergekit MoE (only Qwen3 MoE supported)

## 📜 License

Same as base model: Apache 2.0
