# Arcee **Homunculus-12B** |
|
|
|
|
|
**Homunculus** is a 12 billion-parameter instruction model distilled from **Qwen3-235B** onto the **Mistral-Nemo** backbone. |
|
|
It was purpose-built to preserve Qwen’s two-mode interaction style—`/think` (deliberate chain-of-thought) and `/nothink` (concise answers)—while running on a single consumer GPU. |

## ✨ What’s special? |
|
|
|
|
|
| Feature | Detail | |
|
|
| --------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- | |
|
|
| **Reasoning-trace transfer** | Instead of copying just final probabilities, we align *full* logit trajectories, yielding more faithful reasoning. | |
|
|
| **Total-Variation-Distance loss** | To better match the teacher’s confidence distribution and smooth the loss landscape. | |
|
|
| **Tokenizer replacement** | The original Mistral tokenizer was swapped for Qwen3's tokenizer. | |
|
|
| **Dual interaction modes** | Use `/think` when you want transparent step-by-step reasoning (good for analysis & debugging). Use `/nothink` for terse, production-ready answers. Most reliable in the system role field. | | |

## 🔧 Quick Start |
|
|
|
|
|
```python |
|
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
|
|
|
|
model_id = "arcee-ai/Homunculus" |
|
|
tokenizer = AutoTokenizer.from_pretrained(model_id) |
|
|
model = AutoModelForCausalLM.from_pretrained( |
|
|
model_id, |
|
|
torch_dtype="auto", |
|
|
device_map="auto" |
|
|
) |
|
|
|
|
|
# /think mode - Chain-of-thought reasoning |
|
|
messages = [ |
|
|
{"role": "system", "content": "You are a helpful assistant. /think"}, |
|
|
{"role": "user", "content": "Why is the sky blue?"}, |
|
|
] |
|
|
output = model.generate( |
|
|
tokenizer.apply_chat_template(messages, tokenize=True, return_tensors="pt"), |
|
|
max_new_tokens=512, |
|
|
temperature=0.7 |
|
|
) |
|
|
print(tokenizer.decode(output[0], skip_special_tokens=True)) |
|
|
|
|
|
# /nothink mode - Direct answers |
|
|
messages = [ |
|
|
{"role": "system", "content": "You are a helpful assistant. /nothink"}, |
|
|
{"role": "user", "content": "Summarize the plot of Hamlet in two sentences."}, |
|
|
] |
|
|
output = model.generate( |
|
|
tokenizer.apply_chat_template(messages, tokenize=True, return_tensors="pt"), |
|
|
max_new_tokens=128, |
|
|
temperature=0.7 |
|
|
) |
|
|
print(tokenizer.decode(output[0], skip_special_tokens=True)) |
|
|
``` |
|

|
## 💡 Intended Use & Limitations |
|
|
|
|
|
Homunculus is designed for: |
|
|
|
|
|
* **Research** on reasoning-trace distillation, Logit Imitation, and mode-switchable assistants. |
|
|
* **Lightweight production** deployments that need strong reasoning at <12 GB VRAM. |
|
|
|
|
|
### Known limitations |
|
|
|
|
|
* May inherit biases from the Qwen3 teacher and internet-scale pretraining data. |
|
|
* Long-context (>32 k tokens) use is experimental—expect latency & memory overhead. |
