HunYuanMoEV1

HunYuanMoEV1 is Tencent's mixture-of-experts language model with 80B total parameters and 13B active parameters per token. It uses fine-grained expert routing with Grouped Query Attention, supports 256K context length, and offers dual-mode reasoning (fast and slow thinking).

The example below demonstrates how to generate text with [Pipeline] or the [AutoModelForCausalLM] class.

<hfoptions id="usage"> <hfoption id="Pipeline">
python
from transformers import pipeline


pipe = pipeline(
    task="text-generation",
    model="tencent/Hunyuan-A13B-Instruct",
)
pipe("The future of artificial intelligence is")
</hfoption> <hfoption id="AutoModelForCausalLM">
python
from transformers import AutoModelForCausalLM, AutoTokenizer


tokenizer = AutoTokenizer.from_pretrained("tencent/Hunyuan-A13B-Instruct")
model = AutoModelForCausalLM.from_pretrained(
    "tencent/Hunyuan-A13B-Instruct",
    device_map="auto",
)
input_ids = tokenizer("The future of artificial intelligence is", return_tensors="pt").to(model.device)

output = model.generate(**input_ids, max_new_tokens=50)
print(tokenizer.decode(output[0], skip_special_tokens=True))
</hfoption> </hfoptions>
