Libraries

How to use meituan/DeepSeek-R1-Block-INT8 with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="meituan/DeepSeek-R1-Block-INT8", trust_remote_code=True)
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("meituan/DeepSeek-R1-Block-INT8", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("meituan/DeepSeek-R1-Block-INT8", trust_remote_code=True)
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

-## 0. INT8 Quantization
-We apply a INT8 quantization on the BF16 checkpoints, where weight scales are determined by dividing he block-wise maximum of element values by the INT8 type maximum.
-The quantization script is provided in inference/bf16_case_int8.py.
 ## 1. Introduction
 We introduce our first-generation reasoning models, DeepSeek-R1-Zero and DeepSeek-R1.

+# Block-wise INT8 DeepSeek-R1
+The INT8 data type is both friendly and efficient for most hardware platforms.
+**We provide a block-wise INT8 weight for DeepSeek-R1.**
+In benchmarking, we observe **no accuracy loss** and up to **30\%** performance enhancement.
+[SGLang](https://github.com/sgl-project/sglang/tree/main) will soon support the block-wise INT8 quantization operation once our [PULL REQUEST](https://github.com/sgl-project/sglang/pull/3730) is merged.
+## 1. Benchmarking Result (detailed in [PULL REQUEST](https://github.com/sgl-project/sglang/pull/3730)):
+| Model  | Config | Accuracy (GSM8K) | Accuracy (MMLU) | Output Throughput(qps=128) | Output Throughput(bs=1) |
+|--------|--------|-------------------|----------------|------------------------------|--------------------------|
+| BF16 R1 | (A100\*16)x2 | 95.8              | 87.1           | 4450.02 (+33%)                | 44.18 (+18%)             |
+| INT8 R1 | A100\*32  | 95.5              | 87.1           | 3342.29                       | 37.20                     |
+## 2. Quantization Process
+We apply INT8 quantization to the BF16 checkpoints.
+The weight scales are determined by dividing the block-wise maximum of element values by the INT8 type maximum.
+To generate this weight, run the provided script in the ``./inference`` directory:
+``
+python3 bf16_case_int8.py --input-bf16-hf-path /path/to/bf16-weights/ --output-int8-hf-path /path/to/save-int8-weight/
+``
