# Run Gemma with Keras 3: JAX, PyTorch, or TensorFlow
[](https://github.com/IMvision12/KerasFormers) [](https://imvision12.github.io/KerasFormers/gemma/) [](https://huggingface.co/collections/kerasformers/gemma-6a69aaecae0f1f518733ffa1)
# kerasformers/gemma-7b
Paper: [Gemma: Open Models Based on Gemini Research and Technology (arXiv:2403.08295)](https://arxiv.org/abs/2403.08295) · [HF Papers](https://huggingface.co/papers/2403.08295)
Gemma is Google's open decoder-only LLM family (RMSNorm, GeGLU, RoPE, multi-query attention). Base checkpoints are for completion; `-it` / `1.1` variants are instruction-tuned for chat.
For more details on the model, please go to Google's original [model card](https://huggingface.co/google/gemma-7b).
Pure-**Keras 3** conversion of [`google/gemma-7b`](https://huggingface.co/google/gemma-7b) for [kerasformers](https://github.com/IMvision12/KerasFormers). One implementation runs unmodified on **TensorFlow / Torch / JAX**.
This is a **base** (pretrained) checkpoint: prompt it with raw text completion, or prefer an `-it` variant for chat.
## ✨ Quick start
```python
import os
os.environ["KERAS_BACKEND"] = "torch" # or "jax" / "tensorflow"
from kerasformers.models.gemma import GemmaTextGenerate, GemmaTokenizer
model = GemmaTextGenerate.from_weights("kerasformers/gemma-7b")
tokenizer = GemmaTokenizer.from_weights("kerasformers/gemma-7b")
inputs = tokenizer("The capital of France is")
outputs = model.generate(**inputs, max_new_tokens=32)
print(tokenizer.decode(outputs[0]))
```
Load any Gemma v1 variant the same way with `from_weights("kerasformers/<variant>")`:
| Variant | Hub | Type |
|---|---|---|
| `gemma-2b` | [`kerasformers/gemma-2b`](https://huggingface.co/kerasformers/gemma-2b) | base |
| `gemma-2b-it` | [`kerasformers/gemma-2b-it`](https://huggingface.co/kerasformers/gemma-2b-it) | instruct |
| `gemma-1.1-2b-it` | [`kerasformers/gemma-1.1-2b-it`](https://huggingface.co/kerasformers/gemma-1.1-2b-it) | instruct (1.1) |
| `gemma-7b` | [`kerasformers/gemma-7b`](https://huggingface.co/kerasformers/gemma-7b) | base |
| `gemma-7b-it` | [`kerasformers/gemma-7b-it`](https://huggingface.co/kerasformers/gemma-7b-it) | instruct |
| `gemma-1.1-7b-it` | [`kerasformers/gemma-1.1-7b-it`](https://huggingface.co/kerasformers/gemma-1.1-7b-it) | instruct (1.1) |
## Tips
- Set `KERAS_BACKEND` **before** importing Keras / kerasformers.
- Prefer `GemmaTokenizer.from_weights(...)` so the chat template matches.
- Larger checkpoints: try `load_dtype="bfloat16"` or `quantization="int8"`.
- See [Gemma docs](https://imvision12.github.io/KerasFormers/gemma/) and [Loading Weights](https://imvision12.github.io/KerasFormers/loading_weights/).
- Community / upstream safetensors still work via the `hf:` prefix, e.g. `GemmaTextGenerate.from_weights("hf:google/gemma-7b")`.
## Special Thanks
A huge thank you to the Google Gemma authors for creating and releasing these models.
