## Loading

Install minimal loading dependencies:

```bash
pip install -U transformers accelerate safetensors
```

Example:

```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

repo_id = "mindlab-research/Macaron-V1-Preview-744B-Merged"

tokenizer = AutoTokenizer.from_pretrained(
    repo_id,
    trust_remote_code=True,
)

model = AutoModelForCausalLM.from_pretrained(
    repo_id,
    torch_dtype=torch.bfloat16,
    device_map="auto",
    trust_remote_code=True,
)
model.eval()
```

## Evaluation

For benchmark context and full Macaron-V1-Preview release notes, see the [release blog](https://macaron.im/mindlab/research/macaron-v1-preview) and the [routed 749B model card](https://huggingface.co/mindlab-research/Macaron-V1-Preview-749B). This merged checkpoint is not equivalent to the full routed Mixture-of-LoRA serving stack, so behavior may differ from the 749B release.

Macaron-V1-Preview-744B-Merged is released under the MIT License. Users should also respect any requirements inherited from GLM-5.1 and from dependencies used in deployment.
