Run GLM-4.5V with Keras 3: JAX, PyTorch, or TensorFlow

kerasformers/glm-4.5v

Pure-Keras 3 conversion of zai-org/GLM-4.5V for kerasformers. One implementation runs unmodified on TensorFlow / Torch / JAX. GLM-4.5V is a mixture-of-experts vision-language model (GLM-4V vision tower + GLM-4.5 MoE decoder) served as image + text -> text via Glm4vMoeProcessor; weights are stored in bfloat16, with the MoE router correction bias kept in float32 (matching the upstream mixed-precision checkpoint). See kf_config.json (weight_dtype + weight_dtype_overrides) for the exact layout.

For model details, license, and usage terms, see the upstream model card.

✨ Quick start

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

from PIL import Image
from kerasformers.models.glm4v_moe import Glm4vMoeConditionalGenerate, Glm4vMoeProcessor

model = Glm4vMoeConditionalGenerate.from_weights("kerasformers/glm-4.5v")
processor = Glm4vMoeProcessor.from_weights("kerasformers/glm-4.5v")

inputs = processor(conversation=[
    {"role": "user", "content": [
        {"type": "image", "image": Image.open("photo.jpg")},
        {"type": "text", "text": "Describe this image in one sentence."},
    ]}
])
outputs = model.generate(**inputs, max_new_tokens=64)
print(processor.decode(outputs[0]))

Load any GLM variant the same way with from_weights("kerasformers/<variant>"). Browse them all in the GLM collection.

Special Thanks

A huge thank you to the Zhipu AI / THUDM team for creating and releasing the GLM models.
