Loading

Install minimal loading dependencies:

pip install -U transformers accelerate safetensors

Example:

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 and the routed 749B model card. This merged checkpoint is not equivalent to the full routed Mixture-of-LoRA serving stack, so behavior may differ from the 749B release.
