# Model Card for Qemma |
|
|
|
|
|
**Qemma** is a HuggingFace-native hybrid model that merges **Gemma-3 (1B)** and **Qwen-3 (0.6B)** at the weight level (no adapters). |
|
|
Design: Gemma MLP/body + Qwen attention/head, projected and aligned to Gemma’s hidden size. The model is then SFT-tuned for stepwise reasoning. |
|
|
|
|
|
## Quick start |
|
|
|
|
|
```python |
|
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
|
import torch |
|
|
|
|
|
model_id = "reaperdoesntknow/Qemma-sft" |
|
|
tok = AutoTokenizer.from_pretrained(model_id, use_fast=True) |
|
|
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.bfloat16).eval() |
|
|
|
|
|
messages = [{"role": "user", "content": "Explain finite-scale discrepancy Δ_r in one paragraph."}] |
|
|
inputs = tok.apply_chat_template(messages, tokenize=True, add_generation_prompt=True, return_tensors="pt") |
|
|
|
|
|
out = model.generate(inputs, max_new_tokens=256, do_sample=True, temperature=0.7, top_p=0.9) |
|
|
print(tok.decode(out[0], skip_special_tokens=True)) |
|
|
``` |
|
|
|
|
|
## What’s inside |
|
|
|
|
|
* **Architecture:** Gemma-3 backbone (26 layers, hidden 1152, MLP 6912) with **Qwen-style attention** regrouped to Gemma’s 4×256 heads. |
|
|
* **Tokenizer:** Gemma-3 tokenizer and chat template (see `chat_template.jinja`). |
|
|
* **Training:** SFT for instruction following and stepwise reasoning. |
|
|
|
|
|
## Intended use & limitations |
|
|
|
|
|
**Use:** research, instruction following, code/help, analysis, further SFT/RLHF. |
|
|
**Limits:** may hallucinate; not for safety-critical, medical, legal, or financial decisions. Follow dataset/model licenses. |
|
|
|
|
|
## Training procedure |
|
|
|
|
|
* ~512 warm-start steps (Alpaca-style data) |
|
|
* 256 Additional pretraining steps on (O1-OPEN/OpenO1-SFT) |
|
|
* 128 SFT steps with (Jackrong/gpt-oss-120b-reasoning-STEM-5K) |
|
|
* 256 SFT steps with (O1-OPEN/OpenO1-SFT) |
