zeromodels/gemma-3-270m

Pure-Keras 3 conversion of google/gemma-3-270m for zeromodels. One implementation runs unmodified on TensorFlow / Torch / JAX. This is a base (pretrained) checkpoint, served here as text -> text via Gemma3TextGenerate; weights are stored in bfloat16.

For model details, license, and usage terms, see Google's model card.

✨ Quick start

python

import os
os.environ["KERAS_BACKEND"] = "torch"  # or "jax" / "tensorflow"

from zeromodels.models.gemma3 import Gemma3TextGenerate, Gemma3Tokenizer

model = Gemma3TextGenerate.from_weights("zeromodels/gemma-3-270m")
tokenizer = Gemma3Tokenizer.from_weights("zeromodels/gemma-3-270m")

inputs = tokenizer([{"role": "user", "content": "Hello, who are you?"}])
outputs = model.generate(**inputs, max_new_tokens=64)
print(tokenizer.decode(outputs[0]))

Load any Gemma 3 variant the same way with from_weights("zeromodels/<variant>"):

Tips

Set KERAS_BACKEND before importing Keras / zeromodels.
Loads in bfloat16 by default. Pass load_dtype="float32" for full precision, or quantization="int8" to shrink further.
See the Gemma 3 docs.
Community / upstream weights still work via the hf: prefix: Gemma3TextGenerate.from_weights("hf:google/gemma-3-270m").
