Uses

Direct Use

This model can be directly used for:

• Chinese text generation and rewriting
• Text completion and continuation
• Short dialogue and question answering
• Information extraction and text summarization
• Lightweight content creation and auxiliary writing

Downstream Use [optional]

Can be further fine-tuned for:

• Domain-specific question answering systems
• Customer service chatbots
• RAG (Retrieval-Augmented Generation) systems
• Text classification and sentiment analysis
• Professional document processing

Out-of-Scope Use

• Not designed for high-risk decision-making scenarios such as medical diagnosis, financial investment, or legal advice without professional review
• Not suitable for generating harmful, misleading, illegal, or privacy-violating content
• Not optimized for non-Chinese languages
• Not intended for large-scale long-context reasoning beyond its design limits

Bias, Risks, and Limitations

• The model may inherit social, cultural, and linguistic biases present in the pre-training data of the original Qwen3 model.
• It may produce inaccurate or inconsistent responses to complex professional or sensitive topics.
• Output quality may degrade for extremely colloquial, fragmented, or noisy text inputs.
• The model does not have autonomous fact-checking capabilities and may generate factually incorrect content.

Recommendations

Users should verify key outputs, especially in professional or production environments. Sensitive information and high-stakes scenarios require human supervision. It is recommended to add content filtering mechanisms for public deployment. Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model.

How to Get Started with the Model

Use the code below to load and inference with the model:

from transformers import AutoTokenizer, AutoModelForCausalLM

model_name = "Yougen/Qwen3Fangwusha4B"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

prompt = "请解释一下大模型微调的基本流程"
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=256, temperature=0.7)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
