+## Usage
+### Inference with Transformers
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+import torch
+torch.manual_seed(0)
+
+path = 'openbmb/MiniCPM4-0.5B'
+device = "cuda"
+tokenizer = AutoTokenizer.from_pretrained(path)
+model = AutoModelForCausalLM.from_pretrained(path, torch_dtype=torch.bfloat16, device_map=device, trust_remote_code=True)
+
+# User can directly use the chat interface
+responds, history = model.chat(tokenizer, "Write an article about Artificial Intelligence.", temperature=0.7, top_p=0.7)
+print(responds)
+
+# User can also use the generate interface
+# messages = [
+#     {"role": "user", "content": "Write an article about Artificial Intelligence."},
+# ]
+# prompt_text = tokenizer.apply_chat_template(
+#     messages,
+#     tokenize=False,
+#     add_generation_prompt=True,
+# )
+# model_inputs = tokenizer([prompt_text], return_tensors="pt").to(device)
+
+# model_outputs = model.generate(
+#     **model_inputs,
+#     max_new_tokens=1024,
+#     top_p=0.7,
+#     temperature=0.7
+# )
+# output_token_ids = [
+#     model_outputs[i][len(model_inputs[i]):] for i in range(len(model_inputs['input_ids']))
+# ]
+
+# responses = tokenizer.batch_decode(output_token_ids, skip_special_tokens=True)[0]
+# print(responses)
+```
+
+### Inference with [SGLang](https://github.com/sgl-project/sglang)
+
+For now, you need to install our forked version of SGLang.
+```bash
+git clone -b openbmb https://github.com/OpenBMB/sglang.git
+cd sglang
+
+pip install --upgrade pip
+pip install -e "python[all]"
+```
+
+You can start the inference server by running the following command:
+```bash
+python -m sglang.launch_server --model openbmb/MiniCPM4-0.5B --trust-remote-code --port 30000 --chat-template chatml
+```
+
+Then you can use the chat interface by running the following command:
+```python
+import openai
+
+client = openai.Client(base_url=f"http://localhost:30000/v1", api_key="None")
+
+response = client.chat.completions.create(
+    model="openbmb/MiniCPM4-0.5B",
+    messages=[
+        {"role": "user", "content": "Write an article about Artificial Intelligence."},
+    ],
+    temperature=0.7,
+    max_tokens=1024,
+)
+
+print(response.choices[0].message.content)
+```
+
+### Inference with [vLLM](https://github.com/vllm-project/vllm)
+For now, you need to install the latest version of vLLM.
+```
+pip install -U vllm \
+    --pre \
+    --extra-index-url https://wheels.vllm.ai/nightly
+```
+
+Then you can inference MiniCPM4-0.5B with vLLM:
+```python
+from transformers import AutoTokenizer
+from vllm import LLM, SamplingParams
+
+model_name = "openbmb/MiniCPM4-0.5B"
+prompt = [{"role": "user", "content": "Please recommend 5 tourist attractions in Beijing. "}]
+
+tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True)
+input_text = tokenizer.apply_chat_template(prompt, tokenize=False, add_generation_prompt=True)
+
+llm = LLM(
+    model=model_name,
+    trust_remote_code=True,
+    max_num_batched_tokens=32768, 
+    dtype="bfloat16", 
+    gpu_memory_utilization=0.8, 
+)
+sampling_params = SamplingParams(top_p=0.7, temperature=0.7, max_tokens=1024, repetition_penalty=1.02)
+
+outputs = llm.generate(prompts=input_text, sampling_params=sampling_params)
+
+print(outputs[0].outputs[0].text)
+```
+
+Also, you can start the inference server by running the following command:
+> **Note**: In vLLM's chat API, `add_special_tokens` is `False` by default. This means important special tokens—such as the beginning-of-sequence (BOS) token—will not be added automatically. To ensure the input prompt is correctly formatted for the model, you should explicitly set `extra_body={"add_special_tokens": True}`.
+
+```bash
+vllm serve openbmb/MiniCPM4-0.5B 
+```
+
+Then you can use the chat interface by running the following code:
+
+```python
+import openai
+
+client = openai.Client(base_url="http://localhost:8000/v1", api_key="EMPTY")
+
+response = client.chat.completions.create(
+    model="openbmb/MiniCPM4-0.5B",
+    messages=[
+        {"role": "user", "content": "Write an article about Artificial Intelligence."},
+    ],
+    temperature=0.7,
+    max_tokens=1024,
+    extra_body=dict(add_special_tokens=True),  # Ensures special tokens are added for chat template
+    
+)
+
+print(response.choices[0].message.content)
+```
+
+
+## Evaluation Results
+On two typical end-side chips, Jetson AGX Orin and RTX 4090, MiniCPM4 demonstrates significantly faster processing speed compared to similar-size models in long text processing tasks. As text length increases, MiniCPM4's efficiency advantage becomes more pronounced. On the Jetson AGX Orin platform, compared to Qwen3-8B, MiniCPM4 achieves approximately 7x decoding speed improvement.

+    This is the configuration class to store the configuration of a [`MiniCPMModel`]. It is used to instantiate an MiniCPM
+    model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
+    defaults will yield a similar configuration to that of the MiniCPM-7B.
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+

+            `num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
+            converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
+            by meanpooling all the original heads within that group. For more details checkout [this

+            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`.

+        rope_scaling (`Dict`, *optional*):
+            Dictionary containing the scaling configuration for the RoPE embeddings. Currently supports two scaling
+            strategies: linear and dynamic. Their scaling factor must be a float greater than 1. The expected format is
+            `{"type": strategy name, "factor": scaling factor}`. When using this flag, don't update

+            blocks) that can be used to speed up sequential decoding. This typically consists in the `past_key_values`
+            returned by the model at a previous stage of decoding, when `use_cache=True` or `config.use_cache=True`.
+
+            Two formats are allowed:
+            - a [`~cache_utils.Cache`] instance;
+            - Tuple of `tuple(torch.FloatTensor)` of length `config.n_layers`, with each tuple having 2 tensors of
+            shape `(batch_size, num_heads, sequence_length, embed_size_per_head)`). This is also known as the legacy
+            cache format.
+
+            The model will output the same cache format that is fed as input. If no `past_key_values` are passed, the
+            legacy cache format will be returned.
+
+            If `past_key_values` are used, the user can optionally input only the last `input_ids` (those that don't
+            have their past key value states given to this model) of shape `(batch_size, 1)` instead of all `input_ids`
+            of shape `(batch_size, sequence_length)`.
+        inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
+            Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
+            is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
+            model's internal embedding lookup matrix.
+        use_cache (`bool`, *optional*):
+            If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
+            `past_key_values`).
+        output_attentions (`bool`, *optional*):
+            Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
+            tensors for more detail.
+        output_hidden_states (`bool`, *optional*):
+            Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
+            more detail.
+        return_dict (`bool`, *optional*):
+            Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple.
