🚀 Performance Highlights

Leading MoE Architecture: The open-source Mixture-of-Experts (MoE) diffusion large language model continually trained on the Ling2.0 series with approximately 20 trillion tokens.
Efficient Inference: With 16 billion total parameters, only 1.4 billion are activated during inference. LLaDA2.0-mini significantly reduces computational costs while outperforming open-source dense models of similar scale.
Impressive Performance on Code & Complex Reasoning: Excels in tasks such as code generation and advanced mathematical reasoning, demonstrating strong reasoning capabilities.
Tool Use: Supports tool calling and achieves excellent performance in complex agent-based tasks.
Open & Extensible: Fully open-source with commitment to transparency. We plan to release a leading inference framework in the future and continue investing in cutting-edge areas like diffusion LLMs (dLLM) to drive disruptive innovation.

🗺️ What's Next

Supercharged Reasoning with LLaDA 2.0: LLaDA 2.0 series will be fine-tuned with Reinforcement Learning, unlocking a new level of sophisticated reasoning and problem-solving abilities.
Tools for Innovators: The model was finetuned on the dFactory framework using Fully Sharded Data Parallel (FSDP2). We have begun open-sourcing dFactory and will continuously release our advanced post-training technologies. Whether you want to master the current model or build your own customized versions, you'll have the tools you need. Stay tuned for more updates!

🤗 Hugging Face Transformers

Make sure you have transformers and its dependencies installed:

python

import torch
import torch.nn.functional as F
from transformers import AutoModelForCausalLM
from transformers import AutoTokenizer

model_path = "/path/to/LLaDA2.0-mini"
device = "cuda:0"
model = AutoModelForCausalLM.from_pretrained(
    model_path, trust_remote_code=True, device_map=device
)
model = model.to(torch.bfloat16)
model.eval()
tokenizer = AutoTokenizer.from_pretrained(model_path, trust_remote_code=True)

prompt = "Why does Camus think that Sisyphus is happy?"
input_ids = tokenizer.apply_chat_template(
    [{"role": "user", "content": prompt}],
    add_generation_prompt=True,
    tokenize=True,
    return_tensors="pt",
)
generated_tokens = model.generate(
    inputs=input_ids,
    eos_early_stop=True,
    gen_length=512,
    block_length=32,
    steps=32,
    temperature=0.0,
)
generated_answer = tokenizer.decode(
    generated_tokens[0],
    skip_special_tokens=True,
)
print(generated_answer)

Best Practices

To achieve optimal performance, we recommend the following settings:

Sampling Parameters: We suggest using Temperature=0.0, block_length=32, and steps=32. Using a higher temperature value may occasionally result in language mixing and a slight decrease in model performance.
Adequate Output Length: We recommend using an output length of 32768 tokens for most queries.
