+# WeDLM-7B
+
+**WeDLM-7B** is a diffusion language model that performs parallel decoding under standard causal attention, initialized from [Qwen2.5-7B](https://huggingface.co/Qwen/Qwen2.5-7B).
+
+This is the **base (pretrained)** version. For the instruction-tuned version, see [WeDLM-7B-Instruct](https://huggingface.co/tencent/WeDLM-7B-Instruct).
+
+📄 Paper (Coming Soon) | 🌐 [Project Page](https://wedlm.github.io) | 💻 [GitHub](https://github.com/tencent/WeDLM)
+
+## Model Details
+
+| Attribute | Value |
+|:----------|:------|
+| Initialized From | [Qwen2.5-7B](https://huggingface.co/Qwen/Qwen2.5-7B) |
+| Parameters | 7B |
+| Context Length | 32,768 |
+
+## Quick Start (Recommended)
+
+For **fast inference**, use the `wedlm` engine:
+
+```bash
+pip install git+https://github.com/tencent/WeDLM.git
+```
+
+```python
+from wedlm import LLM, SamplingParams
+
+llm = LLM(model="tencent/WeDLM-7B")
+
+prompt = "The theory of relativity states that"
+outputs = llm.generate([prompt], SamplingParams(temperature=0.7, max_tokens=256))
+
+print(outputs[0]["text"])
+```
+
+## HuggingFace Transformers
+
+For **training** or simple forward passes, you can load via Transformers:
+
+```python
+from transformers import AutoTokenizer, AutoModelForCausalLM
+
+tokenizer = AutoTokenizer.from_pretrained("tencent/WeDLM-7B", trust_remote_code=True)
+model = AutoModelForCausalLM.from_pretrained(
+    "tencent/WeDLM-7B", 
+    trust_remote_code=True,
+    torch_dtype="auto",
+    device_map="auto"
+)
+
+inputs = tokenizer("The theory of relativity", return_tensors="pt").to(model.device)
+outputs = model(**inputs)
+```
+
+> ⚠️ **Note:** The HuggingFace interface is for training/forward pass convenience. For optimized inference throughput, use the `wedlm` engine above.
+

+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        vocab_size (`int`, *optional*, defaults to 151936):
+            Vocabulary size of the WeDLM model. Defines the number of different tokens that can be represented by the
+            `inputs_ids` passed when calling [`WeDLMModel`]
+        hidden_size (`int`, *optional*, defaults to 4096):
+            Dimension of the hidden representations.
+        intermediate_size (`int`, *optional*, defaults to 22016):

+        num_key_value_heads (`int`, *optional*, defaults to 32):
+            This is the number of key_value heads that should be used to implement Grouped Query Attention. If
+            `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
+            `num_key_value_heads=1` the model will use Multi Query Attention (MQA) otherwise GQA is used.
+        hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
+            The non-linear activation function (function or string) in the decoder.
+        max_position_embeddings (`int`, *optional*, defaults to 32768):
+            The maximum sequence length that this model might ever be used with.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        rms_norm_eps (`float`, *optional*, defaults to 1e-06):
+            The epsilon used by the rms normalization layers.
+        use_cache (`bool`, *optional*, defaults to `True`):
+            Whether or not the model should return the last key/values attentions (not used by all models). Only
+            relevant if `config.is_decoder=True`.
+        tie_word_embeddings (`bool`, *optional*, defaults to `False`):
+            Whether the model's input and output word embeddings should be tied.
+        rope_theta (`float`, *optional*, defaults to 10000.0):
+            The base period of the RoPE embeddings.
+        rope_scaling (`Dict`, *optional*):
+            Dictionary containing the scaling configuration for the RoPE embeddings.
+        use_sliding_window (`bool`, *optional*, defaults to `False`):
+            Whether to use sliding window attention.
+        sliding_window (`int`, *optional*, defaults to 4096):
+            Sliding window attention (SWA) window size. If not specified, will default to `4096`.
+        max_window_layers (`int`, *optional*, defaults to 28):
+            The number of layers using full attention.
+        attention_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout ratio for the attention probabilities.
+        attention_bias (`bool`, *optional*, defaults to `True`):
+            Whether to use bias in QKV projections. Set to `True` for Qwen2.5 compatibility,
+            `False` for Qwen3 compatibility.
+        qk_norm (`bool`, *optional*, defaults to `False`):
+            Whether to use QK normalization. Set to `True` for Qwen3 compatibility.
+        head_dim (`int`, *optional*):
