How to use lthn/lemer-hf-bf16 with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="lthn/lemer-hf-bf16")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("lthn/lemer-hf-bf16")
model = AutoModelForMultimodalLM.from_pretrained("lthn/lemer-hf-bf16")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
inputs = processor.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Lemer-HF-bf16 — HuggingFace safetensors format

LEK-aligned Gemma 4 E2B, bf16 reference weights, in HuggingFace safetensors layout.

Converted from lthn/lemer-mlx-bf16 for use on non-MLX platforms (NVIDIA/AMD GPU, Kaggle TPU, vanilla transformers).

Source	This repo
`lthn/lemer-mlx-bf16` (MLX format)	`lthn/lemer-hf-bf16` (HF safetensors)
`language_model.model.*` keys	`model.language_model.*` keys
MLX conv layout (C,K,I) / (O,H,W,I)	PyTorch layout (C,I,K) / (O,I,H,W)

Weights are byte-equivalent to lemer-mlx-bf16 after the key rename + conv permutation — identical LEK alignment, identical behaviour.
