Libraries

How to use SamsungSAILMontreal/Qwen3-30B-A3B-Instruct-2507-HCSMoE with Transformers:

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

pipe = pipeline("text-generation", model="SamsungSAILMontreal/Qwen3-30B-A3B-Instruct-2507-HCSMoE")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForMultimodalLM

tokenizer = AutoTokenizer.from_pretrained("SamsungSAILMontreal/Qwen3-30B-A3B-Instruct-2507-HCSMoE")
model = AutoModelForMultimodalLM.from_pretrained("SamsungSAILMontreal/Qwen3-30B-A3B-Instruct-2507-HCSMoE")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.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)

Qwen3-30B-A3B-Instruct-2507-HCSMoE

This model is a compressed version of Qwen/Qwen3-30B-A3B-Instruct-2507. It is obtained by reducing the number of experts in each MoE layer from 128 to 96 using the HCSMoE baseline method as described in https://bknyaz.github.io/blog/2026/moe/. The compressed model has 23B params (44GB) instead of 31B (57GB) of the original model, reducing storage and GPU memory requirements by roughly 25%. At the same time, the model retains >=93% of the original model's performance on a variety of benchmarks (see Results section below). Additional efficiency optimization (e.g., quantization) can be added similarly to the original model.
