Note: Mirror of openbmb/MiniCPM4.1-8B with a single change to modeling_minicpm.py: the CacheLayerMixin / DynamicLayer import is wrapped in a try/except ImportError fallback so the module imports under transformers < 4.54. This is required for OpenVINO export via optimum-intel, which caps minicpm at transformers 4.53.3. The InfLLMv2 sparse-attention path that uses those names is gated on torch.cuda.is_available() and does not run on the CPU export box. Weights are byte-identical to the upstream model.

Evaluation Results

Performance Evaluation

MiniCPM4.1 launches end-side versions with 8B parameter scale, both achieving best-in-class performance in their respective categories.

Best Practices

It is advisable to use temperature=0.9, topp=0.95. And we suggest setting max_output_token to 65,536 tokens.
For math problems, we recommend using "Please reason step by step, and put your final answer within \boxed{}."
And for English multiple-choice questions, we recommend starting with "Answer the following multiple choice question. The last line of your response should be of the following format: 'ANSWER: $LETTER' (without quotes) where LETTER is one of ABCD. Think step by step before answering." And "你回答的最后一行必须是以下格式 '答案：$选项' (不带引号), 其中选项是ABCD之一。请在回答之前一步步思考" for Chinese MCQ.

Efficiency Evaluation

MiniCPM4.1 adopts sparse attention and speculative decoding to improve the inference efficiency. On RTX 4090, MiniCPM4.1 achieves 3x decoding speed improvement in reasoning.

Examples

Usage

MiniCPM 4.1 can be used with following frameworks: Huggingface Transformers, SGLang, vLLM, and CPM.cu. For the ultimate inference speed, we highly recommend CPM.cu.

MiniCPM4/MiniCPM4.1 supports both dense attention inference and sparse attention inference modes, where vLLM and SGLang currently only support dense inference mode. If you want to use sparse inference mode, please use Huggingface Transformers and CPM.cu.

Dense attention inference: vLLM, SGLang, Huggingface Transformers
Sparse attention inference: Huggingface Transformers, CPM.cu

To facilitate researches in sparse attention, we provide InfLLM-V2 Training Kernels and InfLLM-V2 Inference Kernels.

Inference with Transformers

MiniCPM4.1-8B requires transformers>=4.56.

Inference with Dense Attention

python

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
torch.manual_seed(0)

path = 'openbmb/MiniCPM4.1-8B'
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=32768,
    top_p=0.95,
    temperature=0.6
)
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 Sparse Attention MiniCPM4.1-8B supports InfLLM v2, a sparse attention mechanism designed for efficient long-sequence inference. It requires the infllmv2_cuda_impl library.

You can install it by running the following command:

bash

git clone -b feature_infer https://github.com/OpenBMB/infllmv2_cuda_impl.git
cd infllmv2_cuda_impl
git submodule update --init --recursive
pip install -e . # or python setup.py install 

To enable InfLLM v2, you need to add the sparse_config field in config.json:

json

{
    ...,
    "sparse_config": {
        "kernel_size": 32,
        "kernel_stride": 16,
        "init_blocks": 1,
        "block_size": 64,
        "window_size": 2048,
        "topk": 64,
        "use_nope": false,
        "dense_len": 8192
    }
}

These parameters control the behavior of InfLLM v2:

kernel_size (default: 32): The size of semantic kernels.
kernel_stride (default: 16): The stride between adjacent kernels.
init_blocks (default: 1): The number of initial blocks that every query token attends to. This ensures attention to the beginning of the sequence.
block_size (default: 64): The block size for key-value blocks.
window_size (default: 2048): The size of the local sliding window.
topk (default: 64): The specifies that each token computes attention with only the top-k most relevant key-value blocks.
use_nope (default: false): Whether to use the NOPE technique in block selection for improved performance.
dense_len (default: 8192): Since Sparse Attention offers limited benefits for short sequences, the model can use standard (dense) attention for shorter texts. The model will use dense attention for sequences with a token length below dense_len and switch to sparse attention for sequences exceeding this length. Set this to -1 to always use sparse attention regardless of sequence length.

Long Context Extension MiniCPM4.1 natively supports context lengths of up to 65,536(64k) tokens. For conversations where the total length (including both input and output) significantly exceeds this limit, we recommend using RoPE scaling techniques for effective handling of long texts. We have validated the model's performance on context lengths of up to 131,072 tokens by modifying the LongRoPE factor.

You can apply the LongRoPE factor modification by modifying the model files. Specifically, in the config.json file, adjust the rope_scaling fields.

}

Inference with SGLang

You can inference with SGLang using the standard mode and speculative decoding mode.

Speculative Decoding

For accelerated inference with speculative decoding, follow these steps:

1. Download MiniCPM4.1 Draft Model

First, download the MiniCPM4.1 draft model:

bash

cd /your_path
git clone https://huggingface.co/openbmb/MiniCPM4.1-8B-Eagle3

2. Install EAGLE3-Compatible SGLang

The EAGLE3 adaptation PR has been submitted. For now, use our repository for installation:

bash

git clone https://github.com/LDLINGLINGLING/sglang.git
cd sglang
pip install -e "python[all]"

3. Launch SGLang Server with Speculative Decoding

Start the SGLang server with speculative decoding enabled:

bash

python -m sglang.launch_server \

  --speculative-eagle-topk 1 \
  --speculative-num-draft-tokens 32 \
  --temperature 0.7

4. Client Usage

The client usage remains the same for both standard and speculative decoding:

python

import openai

client = openai.Client(base_url=f"http://localhost:30002/v1", api_key="None")

response = client.chat.completions.create(
    model="openbmb/MiniCPM4.1-8B",
    messages=[
        {"role": "user", "content": "Write an article about Artificial Intelligence."},
    ],
    temperature=0.6,
    max_tokens=32768,
)

print(response.choices[0].message.content)

Note: Make sure to update the port number in the client code to match the server port (30002 in the speculative decoding example).

Configuration Parameters

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:

python -m sglang.launch_server --model openbmb/MiniCPM4.1-8B --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/MiniCPM4.1-8B",
    messages=[
        {"role": "user", "content": "Write an article about Artificial Intelligence."},
    ],
    temperature=0.6,
    max_tokens=32768,
)

print(response.choices[0].message.content)

Inference with vLLM

You can inference with vLLM using the standard mode and speculative decoding mode.

Speculative Decoding

For accelerated inference with speculative decoding using vLLM, follow these steps:

1. Download MiniCPM4.1 Draft Model

First, download the MiniCPM4.1 draft model and change the architectures in config.json as LlamaForCausalLM.

bash

cd /your_path
git clone https://huggingface.co/openbmb/MiniCPM4.1-8B-Eagle3

2. Install EAGLE3-Compatible vLLM

The EAGLE3 vLLM PR has been submitted. For now, use our repository for installation:

bash

git clone https://github.com/LDLINGLINGLING/vllm.git
cd vllm 
pip install -e .

3. Launch vLLM Server with Speculative Decoding

Start the vLLM inference server with speculative decoding enabled. Make sure to update the model path in the speculative-config to point to your downloaded MiniCPM4_1-8B-Eagle3-bf16 folder:

bash

VLLM_USE_V1=1 \
vllm serve openbmb/MiniCPM4.1-8B \
--seed 42 \
--trust-remote-code \
--speculative-config '{
  "model": "your/path/MiniCPM4_1-8B-Eagle3-bf16",
  "num_speculative_tokens": 3,
  "method": "eagle3",
  "draft_tensor_parallel_size": 1
}'

4. Client Usage Example

The client usage remains the same for both standard and speculative decoding:

python

import openai

client = openai.Client(base_url="http://localhost:8000/v1", api_key="EMPTY")

response = client.chat.completions.create(
    model="openbmb/MiniCPM4.1-8B",
    messages=[
        {"role": "user", "content": "Write an article about Artificial Intelligence."},
    ],
    temperature=0.6,
    max_tokens=32768,
    extra_body=dict(add_special_tokens=True),  # Ensures special tokens are added for chat template
)

print(response.choices[0].message.content)

vLLM Configuration Parameters

VLLM_USE_V1=1: Enables vLLM v1 API
--speculative-config: JSON configuration for speculative decoding
- model: Path to the draft model for speculation
- num_speculative_tokens: Number of speculative tokens (default: 3)
- method: Speculative decoding method (eagle3)
- draft_tensor_parallel_size: Tensor parallel size for draft model (default: 1)
--seed: Random seed for reproducibility
--trust-remote-code: Allow execution of remote code for custom models

Standard Inference (Without Speculative Decoding)

For now, you need to install the latest version of vLLM.

bash

pip install -U vllm \
    --pre \
    --extra-index-url https://wheels.vllm.ai/nightly

Then you can inference MiniCPM4.1-8B with vLLM:

python

from transformers import AutoTokenizer
from vllm import LLM, SamplingParams

model_name = "openbmb/MiniCPM4.1-8B"
prompt = [{"role": "user", "content": "Write an article about Artificial Intelligence."}]

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=65536,
    dtype="bfloat16", 
    gpu_memory_utilization=0.8, 
)
sampling_params = SamplingParams(top_p=0.95, temperature=0.6, max_tokens=32768)

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}.

vllm serve openbmb/MiniCPM4.1-8B --trust-remote-code

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/MiniCPM4.1-8B",
    messages=[
        {"role": "user", "content": "Write an article about Artificial Intelligence."},
    ],
    temperature=0.6,
    max_tokens=32768,
    extra_body=dict(add_special_tokens=True),  # Ensures special tokens are added for chat template
    
)

print(response.choices[0].message.content)

Inference with CPM.cu

We recommend using CPM.cu for the inference of MiniCPM4 and MiniCPM4.1. CPM.cu is a CUDA inference framework developed by OpenBMB, which integrates efficient sparse, speculative sampling, and quantization techniques, fully leveraging the efficiency advantages of MiniCPM4 and MiniCPM4.1.

You can install CPM.cu by running the following command:

bash

git clone https://github.com/OpenBMB/cpm.cu.git --recursive
cd cpm.cu
python3 setup.py install

MiniCPM4.1 natively supports context lengths of up to 65,536(64k) tokens. To reproduce the long-text acceleration effect in the paper, we recommend using the LongRoPE factors that have been validated. Change the rope_scaling field in the config.json file as the following to enable LongRoPE.

json

{
    ...,

After modification, you can run the following command to reproduce the long-context acceleration effect (the script will automatically download the model weights from HuggingFace)

python3 tests/test_generate.py

You can run the following command to infer with EAGLE3 speculative decoding algorithm.

bash

python3 -m cpmcu.cli \
    --model-path $BASE_MODEL_PATH \
    --draft-model-path $EAGLE3_DRAFT_MODEL_PATH \
    --prompt-text "Write an article about Artificial Intelligence." \
    --use-eagle3 true

For more details about CPM.cu, please refer to the repo CPM.cu.

Inference with llama.cpp and Ollama

We also support inference with llama.cpp and Ollama.

llama.cpp

You can download the GGUF format of MiniCPM4.1-8B model from huggingface and run it with llama.cpp for efficient CPU or GPU inference.

# case 1: main-cli
./build/bin/llama-cli -m MiniCPM4.1-8B-Q4_K_M.gguf -p "Write an article about Artificial Intelligence." -n 1500

# case 2: server
## launch server
./build/bin/llama-server -m MiniCPM4.1-8B-Q4_K_M.gguf --host 127.0.0.1 --port 8080 -c 4096 -fa on &

## send request
curl -X POST http://127.0.0.1:8080/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-3.5-turbo",
    "messages": [{"role": "user", "content": "Write an article about Artificial Intelligence."}],
    "max_tokens": 1500
  }'

Ollama

Please refer to model hub for model download. After installing ollama package, you can use MiniCPM4.1 with following commands:

ollama run openbmb/minicpm4.1

Hybird Reasoning Mode

MiniCPM4.1 supports hybrid reasoning mode, which can be used in both deep reasoning mode and non-reasoning mode. To enable hybrid reasoning mode. User can set enable_thinking=True in tokenizer.apply_chat_template to enable hybrid reasoning mode, and set enable_thinking=False to enable non-reasoning mode. Similarly, user can directly add /no_think at the end of the query to enable non-reasoning mode. If not add any special token or add /think at the end of the query, the model will enable reasoning mode.

python

# Enable reasoning mode
prompt_text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True,
    enable_thinking=True
)
# Enable non-reasoning mode
prompt_text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True,
    enable_thinking=False
)
