We introduce GroveMoE, a new sparse architecture using adjugate experts for dynamic computation allocation, featuring the following key highlights:

Architecture: Novel adjugate experts grouped with ordinary experts; shared computation is executed once, then reused, cutting FLOPs.
Sparse Activation: 33 B params total, only 3.14–3.28 B active per token.
Traning: Mid-training + SFT, up-cycled from Qwen3-30B-A3B-Base; preserves prior knowledge while adding new capabilities.

Run GroveMoE

🤗 Transformers Quick Start

Below, there are some code snippets on how to get quickly started with running the model. First, install the Transformers library.

$ pip install transformers==4.51.3

Then, copy the snippet from the section that is relevant for your use case.

python

from transformers import AutoModelForCausalLM, AutoTokenizer
model_name = "inclusionAI/GroveMoE-Inst"
# load the tokenizer and the model
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto"
)
# prepare the model input
prompt = "Give me a short introduction to large language model."
messages = [
    {"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True,
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)
# conduct text completion
generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=16384
)
output_ids = generated_ids[0][len(model_inputs.input_ids[0]):].tolist() 
content = tokenizer.decode(output_ids, skip_special_tokens=True)

print("content:", content)

🚀 SGLang Quick Start

For SGLang, you can follow the steps below to deploy:

1️⃣ Install Dependencies

First, clone the repository:

git clone https://github.com/inclusionAI/GroveMoE.git

Then, install Transformers:

shell

cd src/transformers-4.51.3
pip install .

Next, install SGLang:

shell

cd src/sglang-0.4.6.post5
pip install .

2️⃣ Launch the Server

Run the following command to start SGLang:

shell

python -m sglang.launch_server \
  --model-path inclusionAI/GroveMoE-Inst \
  --port 30000 \
  --context-length 32768

3️⃣ Access the API

Once started, the OpenAI-compatible API will be available at http://localhost:30000/v1.

Test it with curl:

shell

curl http://localhost:30000/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{
    "model": "inclusionAI/GroveMoE-Inst",
    "messages": [{"role": "user", "content": "Hello, SGLang!"}]
  }'

llama.cpp

Thanks @CISCai, support for llama.cpp can be found in the implementation at https://github.com/ggml-org/llama.cpp/pull/15510.

Best Practices for Model Configuration

To achieve optimal performance, we recommend the following settings:

Sampling Parameters:
- We suggest using Temperature=0.7, TopP=0.8, TopK=20, and MinP=0. （⚠️ For benchmarking scenarios requiring sampling (e.g., AIME), these parameters must be explicitly configured.）
Adequate Output Length: Set output length to 16,384 tokens for general use cases to accommodate complex reasoning tasks in instruct models.
Standardize Output Format: We recommend using prompts to standardize model outputs when benchmarking.
- Math Problems: Include "Please reason step by step, and put your final answer within \boxed{}." in the prompt.
- Multiple-Choice Questions: Add the following JSON structure to the prompt to standardize responses: "Please show your choice in the answer field with only the choice letter, e.g., "answer": "C"."
