Instructions to use fredzzp/open-dcoder-0.5B with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use fredzzp/open-dcoder-0.5B with Transformers:

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

pipe = pipeline("text-generation", model="fredzzp/open-dcoder-0.5B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("fredzzp/open-dcoder-0.5B")
model = AutoModelForCausalLM.from_pretrained("fredzzp/open-dcoder-0.5B")
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)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Open Diffusion Large Language Models for Code Generation

This repository contains the weights and custom code for the fredzzp/open-dcoder-0.5B model, a masked diffusion model for code generation based on the Qwen2 architecture.

This model uses bidirectional attention and must be used with the custom diffusion_generate method.

How to Use

First, make sure you have the latest transformers library installed.

pip install transformers torch huggingface_hub

You can then use the model for generation. Note: You must pass trust_remote_code=True to load the custom model architecture.

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM

model_id = "fredzzp/open-dcoder-0.5B"
device = "cuda" if torch.cuda.is_available() else "cpu"

# trust_remote_code=True is essential
tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    trust_remote_code=True
).to(device)

prompt = "def fibonacci(n):"
input_ids = tokenizer(prompt, return_tensors="pt").input_ids.to(device)

# The model will use the generation_config.json from the repo by default
# You can also override parameters here
outputs = model.diffusion_generate(
    inputs=input_ids,
    max_new_tokens=100,
    steps=16,
    temperature=0.8
)

# Decode the output
prompt_len = input_ids.shape[1]
generated_text = tokenizer.decode(outputs.sequences[0][prompt_len:], skip_special_tokens=True)

print("--- Generated Code ---")
print(generated_text)
