1. Model Overview

The openPangu-Embedded-7B is an efficient large language model trained from scratch based on the Ascend NPU. It contains 7 billion parameters (excluding the vocabulary embedding layer). The model has been trained on approximately 19T tokens and is capable of integrating both fast and slow thinking.

3. Benchmark

Note: The system prompt is left empty, and no additional Chain-of-Thought (CoT) prompts are introduced during the evaluation. All evaluations are performed using a sequence length of 128k tokens.

4. Usage

4.3 Inference with Transformers

from transformers import AutoModelForCausalLM, AutoTokenizer

model_local_path = "FreedomIntelligence/openPangu-Embedded-7B"


# load the tokenizer and the model
tokenizer = AutoTokenizer.from_pretrained(
    model_local_path, 
    use_fast=False, 
    trust_remote_code=True,
    local_files_only=True
)

model = AutoModelForCausalLM.from_pretrained(
    model_local_path,
    trust_remote_code=True,
    torch_dtype="auto",
    device_map="auto",
    local_files_only=True
)

# prepare the model input
sys_prompt = "You must strictly comply with laws, regulations, and social ethics." \
    "When generating content, avoid involving violence, pornography, terrorism, racial discrimination, gender discrimination, or other inappropriate content." \
    "If such tendencies are detected in the input or output, refuse to answer and issue a warning. For example, if the input contains violent threats or pornographic descriptions," \
    "return an error message: 'Your input contains inappropriate content and cannot be processed.'"

prompt = "Give me a short introduction to large language model."
no_thinking_prompt = prompt+" /no_think"
messages = [
    {"role": "system", "content": sys_prompt}, # define your system prompt here
    {"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
outputs = model.generate(**model_inputs, max_new_tokens=32768, eos_token_id=45892, return_dict_in_generate=True)

input_length = model_inputs.input_ids.shape[1]
generated_tokens = outputs.sequences[:, input_length:]
output_sent = tokenizer.decode(generated_tokens[0])

# parsing thinking content
thinking_content = output_sent.split("[unused17]")[0].split("[unused16]")[-1].strip()
content = output_sent.split("[unused17]")[-1].split("[unused10]")[0].strip()

print("\nthinking content:", thinking_content)
print("\ncontent:", content)

The openPangu-Embedded-7B model is in slow thinking mode by default, and can be switched to fast thinking mode by the following means:

• In the code example, the definition of the no_thinking_prompt variable demonstrates the specific implementation for switching to fast thinking mode: by appending the /no_think tag at the end of user input, the current turn can be switched to fast thinking mode. In this mode, thinking_content will be an empty value.
