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.
