High Accuracy and efficiency multi-task fine-tuning framework for Code LLMs.
CodeFuse-MFTCoder is an open-source project of CodeFuse for multitasking Code-LLMs(large language model for code tasks), which includes models, datasets, training codebases and inference guides. In MFTCoder, we released two codebases for finetuning Large Language Models:
mft_peft_hfis based on the HuggingFace Accelerate and deepspeed framework.mft_atorchis based on the ATorch frameworks, which is a fast distributed training framework of LLM.
The aim of this project is to foster collaboration and share advancements in large language models, particularly within the domain of code development.
✅ Multi-task: Train models on multiple tasks while maintaining a balance between them. The models can even generalize to new, previously unseen tasks.
✅ Multi-model: It integrates state-of-the-art open-source models such as gpt-neox, llama, llama-2, baichuan, Qwen, chatglm2, and more. (These finetuned models will be released in the near future.)
✅ Multi-framework: It provides support for both HuggingFace Accelerate (with deepspeed) and ATorch.
✅ Efficient fine-tuning: It supports LoRA and QLoRA, enabling fine-tuning of large models with minimal resources. The training speed meets the demands of almost all fine-tuning scenarios.
The main components of this project include:
- Support for both SFT (Supervised FineTuning) and MFT (Multi-task FineTuning). The current MFTCoder achieves data balance among multiple tasks, and future releases will achieve a balance between task difficulty and convergence speed during training.
- Support for QLoRA instruction fine-tuning, as well as LoRA fine-tuning.
- Support for most mainstream open-source large models, particularly those relevant to Code-LLMs, such as Code-LLaMA, Starcoder, Codegeex2, Qwen, GPT-Neox, and more.
- Support for weight merging between the LoRA adaptor and base models, simplifying the inference process.
- Release of 2 high-quality code-related instruction fine-tuning datasets: Evol-instruction-66k and CodeExercise-Python-27k.
- Release of 2 models: CodeFuse-13B and CodeFuse-CodeLlama-34B.
To begin, ensure that you have successfully installed CUDA (version >= 11.4, preferably 11.7) along with the necessary drivers. Additionally, make sure you have installed torch (version 2.0.1).
Next, we have provided an init_env.sh script to simplify the installation of required packages. Execute the following command to run the script:
sh init_env.shIf you require flash attention, please refer to the following link for installation instructions: https://github.com/Dao-AILab/flash-attention

🚀 Atorch Codebase for MFT(Multi-task Finetuning)
We are excited to release the following two CodeLLMs trained by MFTCoder, now available on Hugging Face:
| Model | Base Model | Num of examples trained | Batch Size | Seq Length |
|---|---|---|---|---|
| 🔥🔥🔥 CodeFuse-CodeLlama-34B | CodeLlama-34b-Python | 600k | 80 | 4096 |
| 🔥🔥🔥 CodeFuse-CodeLlama-34B-4bits | CodeLlama-34b-Python | 4096 | ||
| 🔥🔥🔥 CodeFuse-StarCoder-15B | Starcoder | 600k | 256 | 4096 |
| 🔥🔥🔥 CodeFuse-QWen-14B | Qwen-14b | 1100k | 256 | 4096 |
| 🔥 CodeFuse-13B | CodeFuse-13B | 66k | 64 | 4096 |
We are also pleased to release two code-related instruction datasets, meticulously selected from a range of datasets to facilitate multitask training. Moving forward, we are committed to releasing additional instruction datasets covering various code-related tasks.
| Dataset | Description |
|---|---|
| ⭐ Evol-instruction-66k | Based on open-evol-instruction-80k, filter out low-quality, repeated, and similar instructions to HumanEval, thus get high-quality code instruction dataset. |
| ⭐ CodeExercise-Python-27k | python code exercise instruction dataset generated by chatgpt |
