Fine-tune Qwen in Alibaba Cloud Model Studio using an HTTP API.

Important

This topic is applicable only to the International Edition (Singapore region).

Prerequisites

  • You understand fine-tuning concepts, procedures, and data format requirements.

  • You have activated Model Studio and got an API key. See Create an API key.

Fine-tuning overview

Fine-tuning improves model performance:

  • Improve performance for specific industries or businesses

  • Reduce output latency

  • Suppress hallucinations

  • Align outputs with human values or preferences

  • Replace larger models with fine-tuned lightweight models

During fine-tuning, the model learns business- and scenario-specific features from your training data, such as domain knowledge, tone, communication style, and self-awareness. Because the model has already learned many industry- or scenario-specific examples during pre-training, its zero-shot or one-shot performance after fine-tuning surpasses the base model’s few-shot performance. This reduces input tokens and lowers output latency.

Dataset tips

Size requirements

SFT datasets require at least 1,000 high-quality entries. If evaluation results are unsatisfactory, collect more training data.

If you do not have enough data, consider building an agent application with a knowledge base. In many complex business scenarios, fine-tuning and knowledge base retrieval work best together.

For example, in a customer service scenario, fine-tune the model to adjust its tone, expression habits, and self-awareness, then use a knowledge base to dynamically inject domain knowledge into the context.

Try retrieval-augmented generation (RAG) first. After collecting enough data, use fine-tuning to further improve performance.

You can expand your dataset using the following strategies:

  1. Use a larger, high-performing model to generate content for specific businesses or scenarios.

  2. Manually collect data from various sources, such as application scenarios, web scraping, social media, forums, public datasets, partners, industry resources, and user contributions.

Data diversity and balance

For domain-specific use cases, domain expertise is the most important factor. For Q&A scenarios, generalization matters more. Design data samples based on your business modules or scenarios. Training quality depends on data volume, domain specificity, and diversity.

For example, in an AI assistant scenario, a professional and diverse dataset should include the following:

BusinessDiverse scenarios and use cases
BusinessDiverse scenarios and use cases
E-commerce customer servicePromotion pushes, pre-sales consultation, in-sales guidance, after-sales service, follow-up visits, complaint handling, and more.
Financial servicesLoan consultation, investment and financial advice, credit card services, bank account management, and more.
Online healthcareSymptom consultation, appointment scheduling, visit instructions, drug information queries, health tips, and more.
AI secretaryIT information, administrative information, HR information, employee benefit Q&A, company calendar queries, and more.
Travel assistantTravel planning, entry and exit guides, travel insurance consultation, destination customs and culture introductions, and more.
Corporate legal counselContract review, intellectual property protection, compliance checks, labor law Q&A, cross-border transaction consultation, case-specific legal analysis, and more.

Balance the data volume across scenarios to match actual usage ratios. This prevents bias toward any single feature type and improves generalization.

SFT training set

SFT for thinking model

SFT for image understanding (Qwen-VL)

SFT uses training data in Chat Markup Language (ChatML) format, which supports multi-turn conversations and multiple role settings.

The OpenAI name and weight parameters are not supported. All assistant outputs are trained.

json
# A line of training data (JSON format), the typical structure is as follows when expanded:
{"messages": [\
  {"role": "system", "content": "System input 1"},\
  {"role": "user", "content": "User input 1"},\
  {"role": "assistant", "content": "Expected model output 1"},\
  {"role": "user", "content": "User input 2"},\
  {"role": "assistant", "content": "Expected model output 2"}\
  ...\
]}

For details about the system, user, and assistant roles, see Overview of text generation models. Sample training sets: SFT-ChatML_format_example.jsonl and SFT-ChatML_format_example.xlsx. XLS and XLSX formats support only single-turn conversations.

For a single training entry, all assistant rows support the "loss_weight" parameter, which sets the relative importance during training. The valid values range from 0.0 to 1.0. Higher values indicate greater importance.

This parameter is in invitational preview. To use it, you can contact your account manager.

json
 {"role": "assistant", "content": "Expected model output 1", "loss_weight": 1.0},
 {"role": "assistant", "content": "Expected model output 2", "loss_weight": 0.5}

The training data supports multi-turn conversations and multiple role settings, but only the final assistant output is trained.

The \n characters before and after the think tags must be retained.

json
# A line of training data (JSON format), the typical structure is as follows when expanded:
{"messages": [\
  {"role": "system", "content": "System input 1"},\
  {"role": "user", "content": "User input 1"},\
  {"role": "assistant", "content": "Model output 1"}, --Intermediate assistant outputs should not have <think> tags\
   ...\
  {"role": "user", "content": "User input 2"},\
  {"role": "assistant", "content": "<think>\nExpected thinking content 2\n</think>\n\nExpected output 2"} --Thinking content can only be included in the final assistant output.\
]}

For details about the system, user, and assistant roles, see Overview of text generation models. Sample training set: SFT-deep_thinking_content_example.jsonl.

You can configure the model to omit the <think> tag in training samples. If you use this output method, do not enable the thinking mode for calls after the model is trained.

json
{"role": "assistant", "content": "Expected model output 2"}  --Tells the model not to enable thinking

The final assistant row of a single training entry supports the "loss_weight" parameter, which sets the relative importance during training. The valid values range from 0.0 to 1.0. Higher values indicate greater importance.

This parameter is in invitational preview. To use it, you can contact your account manager.

json
 {"role": "assistant", "content": "<think>\nExpected thinking content 2\n</think>\n\nExpected output 2", "loss_weight": 1.0}

The OpenAI name and weight parameters are not supported. All assistant outputs are trained.

For more information about the differences between the system, user, and assistant roles, see Overview of text generation models. Sample training data in ChatML format:

json
# A line of training data (JSON format), the typical structure is as follows when expanded:
{"messages":[\
  {"role":"user",\
    "content":[\
      {"text":"User input 1"},\
      {"image":"Image file name 1"}]},\
  {"role":"assistant",\
    "content":[\
      {"text":"Expected model output 1"}]},\
  {"role":"user",\
    "content":[\
      {"text":"User input 2"}]},\
  {"role":"assistant",\
    "content":[\
      {"text":"Expected model output 2"}]},\
  ...\
  ...\
  ...\
 ]}

Note

If you train a thinking model, you must follow the data format requirements for SFT for thinking model.

The following are the requirements for ZIP files:

  1. Format: ZIP. Maximum size: 2 GB. The folder and file names within the ZIP file must contain only ASCII letters (a–z, A–Z), numbers (0–9), underscores (_), and hyphens (-).

  2. The training text data file must be named data.jsonl and placed in the root directory of the ZIP file. Ensure that the data.jsonl file appears immediately when you open the ZIP file.

  3. A single image cannot exceed 1024 pixels in width or height. The maximum size is 10 MB. Supported formats: .bmp, .jpeg /.jpg, .png, .tif /.tiff, and .webp.

  4. Image file names cannot be duplicated, even if the files are stored in different folders.

  5. ZIP file directory structure:

Single-level directory (recommended)

Multi-level directory

The image files and the data.jsonl file reside in the root directory of the ZIP file.

markdown
Trainingdata_vl.zip
      |--- data.jsonl # Note: Do not wrap in an outer folder
      |--- image1.png
      |--- image2.jpg
  1. The data.jsonl file must be in the root directory of the ZIP file.

  2. In the data.jsonl file, you can declare only the image file name, not the file path. For example:

    Correct: image1.jpg. Incorrect: jpg_folder/image1.jpg.

  3. Image file names must be globally unique within the ZIP file.

markdown
Trainingdata_vl.zip
    |--- data.jsonl # Note: Do not wrap in an outer folder
    |--- jpg_folder
    |   └── image1.jpg
    |--- png_folder

weight_decay0.1Use the default value.FloatL2 regularization strength. Helps maintain model generalization. If too high, fine-tuning effects are insignificant.
Parameters for efficient SFT (supportsefficient_sft ) Note When you perform a second round of efficient fine-tuning on a model that has already been efficiently fine-tuned, the lora_rank, lora_alpha, and lora_dropout parameters must be consistent.
lora_rank864IntegerRank of the low-rank matrix in LoRA. Higher ranks improve fine-tuning results but slightly slow down training.
lora_alpha32Use the default value.IntegerScaling factor that controls the balance between original model weights and LoRA corrections. Larger values give more weight to LoRA corrections, making the model more task-specific. Smaller values preserve more pre-trained model knowledge.
lora_dropout0.1Use the default value.FloatDropout rate for LoRA low-rank matrix values. The recommended value enhances generalization. If too high, fine-tuning effects are insignificant.
Parameters for publishing checkpoints
save_strategyepochCan be set to epoch or steps. - When set to steps, set the save_steps parameter to adjust the saving interval.StringControls the interval and maximum number of checkpoints saved during fine-tuning.
save_steps50To modify it, set it to an integer multiple of the eval_steps parameter.IntegerNumber of training steps after which a checkpoint is saved.
save_total_limit110IntegerMaximum number of checkpoints to save for export.
