# Model Card for Qemma |
|
|
**Redux** This Model underwent an additional merge between Qemma-sft and Qwen3-0.6B, in addition to adding Rope Scaling. |
|
|
**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. |
|
|
This variant uses Yarn based Rope Scaling with 1:1 Ratio from max_position_embeddings |
|
|
## Quick start |
|
|
|
|
|
```python |
|
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
|
import torch |
|
|
|
|
|
model_id = "reaperdoesntknow/Qemma-redux" |
|
|
tokenizer = AutoTokenizer.from_pretrained(model_id, use_fast=True) |
|
|
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.bfloat16).eval() |
|
|
|
|
|
text = "I notice that the sum involves the absolute values of three linear expressions of x." |
|
|
inputs = tokenizer(text, return_tensors="pt", max_length=64, padding='max_length', truncation=True) |
|
|
inputs = {k: v.to(model.device) for k, v in inputs.items()} |
|
|
|
|
|
with torch.no_grad(): |
|
|
model.eval() |
|
|
outputs = model.generate(**inputs, max_new_tokens=256, do_sample=True, min_length=32) |
|
|
print(tokenizer.decode(outputs[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) |
