Model Card for CodeFuse-13B

[中文] [English]

Model Description

CodeFuse-13B is a 13 billion parameter code generation model trained on the GPT-NeoX framework, capable of handling code sequences of up to 4096 characters. This model was pretrained on a dataset consisting of 1000B token code, Chinese, and English data, covering over 40 programming languages. To further enhance the effectiveness and quality of the generated code, the model was fine-tuned on the CodeFuse-Evol-instruction-66k dataset, enabling it to produce more accurate, efficient, and compliant code. Pass@1 achieved 37.1% on the HumanEval evaluation set(BeamSearch strategy, BeamSize=3).

Quickstart

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained(("CodeFuse-13B"))
model = AutoModelForCausalLM.from_pretrained(("CodeFuse-13B"), device_map="auto").half().eval()

input_ids = tokenizer.encode("# language: Python\ndef quick_sort(array):\n", return_tensors="pt").to("cuda")
output_ids = model.generate(input_ids, max_new_tokens=200)

print(tokenizer.decode(output_ids[0]))
