ADAPT-DIFF: Qwen 3.5 0.8B Bidirectional Latent Diffusion Model

This is the public release of ADAPT-DIFF built over a bidirectional Qwen/Qwen3.5-0.8B backbone. It implements a two-stage hybrid generation framework:

Parallel Latent Diffusion Initialization: Generates a block of tokens in parallel via custom LDM heads.
Logit Uncertainty Refinement: Uses a dynamic entropy router and an Actor-Critic tree-search to refine uncertain tokens at high-precision bfloat16.

How to Load the Weights

Because this model utilizes custom architectures, you must define the A2DQwenLMHeadModel and StackedLDMHeads classes in your script, then load the weights as follows:

python

import torch
import transformers
from huggingface_hub import hf_hub_download

# 1. Initialize and load the bidirectional base LLM
base_model = transformers.AutoModel.from_pretrained("dataopsnick/adapt-diff-qwen-0.8b", torch_dtype=torch.bfloat16)

# 2. Download and load the custom LDM projection head weights
ldm_weights_path = hf_hub_download(repo_id="dataopsnick/adapt-diff-qwen-0.8b", filename="ldm_heads.pt")
ldm_heads.load_state_dict(torch.load(ldm_weights_path))

Full Inference Benchmarks & SFT Calibration

To run the complete benchmark comparison against the autoregressive baseline or to perform Supervised Fine-Tuning (SFT) calibration on your own system, clone this repository and execute the dedicated scripts included in the repository:

1. Run Comparative Benchmarking (GSM8K & MBPP)

python infer.py

2. Run Head Alignment & SFT Training
