Model Description

CodeFuse-DeepSeek-33B-4bits is the 4-bit quantized version of CodeFuse-DeepSeek-33B which is a 33B Code-LLM finetuned by QLoRA on multiple code-related tasks on the base model DeepSeek-Coder-33B.

After undergoing 4-bit quantization, the CodeFuse-DeepSeek-33B-4bits model can be loaded on either a single A10 (24GB VRAM) or an RTX 4090 (24GB VRAM). Moreover, the quantized model still achieves an impressive accuracy of 78.05% on the HumanEval pass@1 metric.

Inference String Format

The inference string is a concatenated string formed by combining conversation data (system, human and bot contents) in the training data format. It is used as input during the inference process. Here are examples of prompts used to request the model:

Multi-Round with System Prompt:

"""
<s>system
System instruction
<s>human
Human 1st round input
<s>bot
Bot 1st round output<|end▁of▁sentence|>
<s>human
Human 2nd round input
<s>bot
Bot 2nd round output<|end▁of▁sentence|>
...
...
...
<s>human
Human nth round input
<s>bot
"""

Single-Round without System Prompt:

"""
<s>human
User prompt...
<s>bot

"""

In this format, the system section is optional and the conversation can be either single-turn or multi-turn. When applying inference, you always make your input string end with "<s>bot\n" to ask the model generating answers.

For example, the format used to infer HumanEval is like the following:

<s>human
# language: Python
from typing import List
def separate_paren_groups(paren_string: str) -> List[str]:
    """ Input to this function is a string containing multiple groups of nested parentheses. Your goal is to
    separate those group into separate strings and return the list of those.
    Separate groups are balanced (each open brace is properly closed) and not nested within each other
    Ignore any spaces in the input string.
    >>> separate_paren_groups('( ) (( )) (( )( ))')
    ['()', '(())', '(()())']
    """
<s>bot

Specifically, we also add the Programming Language Tag (e.g. "# language: Python" for Python) used by CodeGeex models.

推理数据格式

推理数据为模型在训练数据格式下拼接的字符串形式,它也是推理时输入prompt拼接的方式. 下面分别是带系统提示的多轮会话格式和不带系统提示的单轮会话格式:

带System提示的多轮会话格式:

"""
<s>system
System instruction
<s>human
Human 1st round input
<s>bot
Bot 1st round output<|end▁of▁sentence|>
<s>human
Human 2nd round input
<s>bot
Bot 2nd round output<|end▁of▁sentence|>
...
...
...
<s>human
Human nth round input
<s>bot
"""

不带System提示的单轮会话格式:

"""
<s>human
User prompt...
<s>bot

"""

在这个格式中,System提示是可选的(按需设定),支持单轮会话也支持多轮会话。推理时,请确保拼接的prompt字符串以"<s>bot\n"结尾,引导模型生成回答。

例如,推理HumanEval数据时使用的格式如下所示:

<s>human
# language: Python
from typing import List
def separate_paren_groups(paren_string: str) -> List[str]:
    """ Input to this function is a string containing multiple groups of nested parentheses. Your goal is to
    separate those group into separate strings and return the list of those.
    Separate groups are balanced (each open brace is properly closed) and not nested within each other
    Ignore any spaces in the input string.
    >>> separate_paren_groups('( ) (( )) (( )( ))')
    ['()', '(())', '(()())']
    """
<s>bot

特别地,我们也使用了CodeGeeX系列模型采用的编程语言区分标签(例如,对于Python语言,我们会使用"# language: Python")。
