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-it). Pure-**Keras 3** conversion of [`google/gemma-7b-it`](https://huggingface.co/google/gemma-7b-it) for [kerasformers](https://github.com/IMvision12/KerasFormers). One implementation runs unmodified on **TensorFlow / Torch / JAX**. This is an **instruction-tuned** checkpoint: use the chat template via `GemmaTokenizer`. ## ✨ 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-it") tokenizer = GemmaTokenizer.from_weights("kerasformers/gemma-7b-it") inputs = tokenizer([ {"role": "user", "content": "Explain rotary embeddings in one sentence."} ]) outputs = model.generate(**inputs, max_new_tokens=64) print(tokenizer.decode(outputs[0])) ``` Load any Gemma v1 variant the same way with `from_weights("kerasformers/")`: | 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-it")`. ## Special Thanks A huge thank you to the Google Gemma authors for creating and releasing these models.
