English Version

We are thrilled to hear about the open-source release of Qwen3 and Qwen3-MoE. The CPT/SFT/DPO/GRPO for Qwen3/Qwen3-MoE has been supported at the first time by the ms-swift large model training framework. Meanwhile, it also supports the Megatron training (CPT/SFT) implementation for Qwen3/Qwen3-MoE, which is 10 times faster than the training speed achieved using transformers on MoE models.

We will showcase a runnable fine-tuning demo and provide the format for custom datasets.

Before starting the fine-tuning process, please ensure that your environment is properly set up.

# pip install git+https://github.com/modelscope/ms-swift.git
git clone https://github.com/modelscope/ms-swift.git
cd ms-swift
pip install -e .

pip install liger-kernel transformers -U

Qwen3-8B GRPO

Taking Qwen3-8B as an example, the following uses the ms-swift framework to conduct GRPO training. For more details about GRPO, refer to the GRPO documentation: https://swift.readthedocs.io/en/latest/Instruction/GRPO.html

The AI-MO/NuminaMath-TIR dataset is used, and the accuracy function is employed to compute the model’s response accuracy reward. The following environment needs to be installed to calculate rewards:

pip install math_verify==0.5.2

The custom dataset format is similar to SFT, where the assistant part is optional. If using the accuracy reward, a solution column is required to compute the accuracy.

{"messages": [{"role": "system", "content": "You are a useful and harmless assistant"}, {"role": "user", "content": "Tell me tomorrow's weather"}]}
{"messages": [{"role": "system", "content": "You are a useful and harmless math calculator"}, {"role": "user", "content": "What is 1 + 1?"}, {"role": "assistant", "content": "It equals 2"}, {"role": "user", "content": "What about adding 1?"}]}
{"messages": [{"role": "user", "content": "What is your name?"}]}

You can also train with custom reward functions or reward models. Columns in the dataset will be passed into **kwargs of the reward function. An example of a custom reward function can be found here: swift/examples/train/grpo/plugin/plugin.py

    --external_plugins examples/train/grpo/plugin/plugin.py \
    --reward_funcs external_math_acc external_math_format \
    --reward_model AI-ModelScope/Skywork-Reward-Llama-3.1-8B-v0.2

During training, we use vLLM to accelerate the sampling process. Setting num_infer_workers=8, we deploy one vLLM engine on each device to speed up the sampling process.

Qwen3-30B-A3B MoE SFT (Megatron-SWIFT)

ms-swift introduces Megatron's parallel technology to accelerate large model training, including data parallelism, tensor parallelism, pipeline parallelism, sequence parallelism, context parallelism, and expert parallelism. It supports pre-training and fine-tuning of models like Qwen3, Qwen3-MoE, Qwen2.5, Llama3, Deepseek-R1 distillation series, etc.

For environment preparation (image) and the conversion between HF and MCore model weights, please refer to the Megatron-SWIFT training documentation; it is not covered here: https://swift.readthedocs.io/en/latest/Instruction/Megatron-SWIFT-Training.html

We use DLC to initiate the training command. The training environment consists of 2 machines with 8 * 80GiB A800:

More multi-node launch methods can be found here: https://github.com/modelscope/ms-swift/tree/main/examples/train/multi-node

# https://help.aliyun.com/zh/pai/user-guide/general-environment-variables

非常高兴听到Qwen3和Qwen3-MoE的开源， ms-swift大模型训练框架首发支持了Qwen3/Qwen3-MoE的CPT/SFT/DPO/GRPO，同时支持了Qwen3/Qwen3-MoE的Megatron训练(CPT/SFT)实现，在MoE模型上相比transformers实现的训练速度快10倍。

我们将展示可运行的微调demo，并给出自定义数据集的格式。

在开始微调之前，请确保您的环境已准备妥当。

Qwen3-8B GRPO

以Qwen3-8B为例，下面使用swift框架对进行GRPO训练。更多关于GRPO，可以参考GRPO文档：https://swift.readthedocs.io/zh-cn/latest/Instruction/GRPO.html

使用AI-MO/NuminaMath-TIR作为数据集，并使用accuracy函数计算模型回答的准确率奖励, 计算奖励需要安装以下环境：

pip install math_verify==0.5.2

自定义数据集格式与SFT类似，其中assistant部分不必需。如果使用accuracy奖励，则需要solution列来计算准确率。

{"messages": [{"role": "system", "content": "You are a useful and harmless assistant"}, {"role": "user", "content": "Tell me tomorrow's weather"}]}
{"messages": [{"role": "system", "content": "You are a useful and harmless math calculator"}, {"role": "user", "content": "What is 1 + 1?"}, {"role": "assistant", "content": "It equals 2"}, {"role": "user", "content": "What about adding 1?"}]}
{"messages": [{"role": "user", "content": "What is your name?"}]}

也可以使用自定义的奖励函数/奖励模型进行训练，数据集中的列会传到奖励函数的**kwargs中，自定义奖励函数的例子参考：swift/examples/train/grpo/plugin/plugin.py

    --external_plugins examples/train/grpo/plugin/plugin.py \
    --reward_funcs external_math_acc external_math_format \
    --reward_model AI-ModelScope/Skywork-Reward-Llama-3.1-8B-v0.2

在训练过程中，我们使用vLLM来加速采样过程。设置num_infer_workers=8，我们为每个device都部署一个vLLM engine来加速采样过程。

训练脚本如下：

# 70G*8
CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 \

Qwen3-30B-A3B MoE SFT（Megatron-SWIFT）

SWIFT引入了Megatron的并行技术来加速大模型的训练，包括数据并行、张量并行、流水线并行、序列并行，上下文并行，专家并行。支持Qwen3、Qwen3-MoE、Qwen2.5、Llama3、Deepseek-R1蒸馏系等模型的预训练和微调。

对于环境准备（镜像）和HF与MCore模型权重的转换，可以参考Megatron-SWIFT训练文档，这里不进行介绍：https://swift.readthedocs.io/zh-cn/latest/Instruction/Megatron-SWIFT%E8%AE%AD%E7%BB%83.html

已加入自我认知微调的demo

qingzhong1 · 2025-04-29T09:07:05Z

If I currently have data without a reasoning process, but I want to use this data to fine-tune Qwen3, should I simply add /no_think after the prompt and prefix the response with <think>\n\n</think>\n\n?

Perhaps you can refer to this for a solution:

ms-swift/swift/llm/dataset/dataset/llm.py

Line 835 in 51cafe5

row['query'] = row['query'] + ' /no_think'

如何将微调成功后的模型导出为GGUF格式？
请求增加一个用于将通过ms-swift微调后的模型转为GGUF格式文件的Notebook文件

row['query'] = row['query'] + ' /no_think'

@Jintao-Huang 在不采用推理的情况下，是否仍然可以使用Qwen2.5 的模板微调模型？

When using --packing true, please additionally use --attn_impl flash_attn. This was missed in the best practices.
