**PsyLLM** is a large language model designed for **psychological counseling and mental health dialogue generation**. It integrates **diagnostic reasoning** and **therapeutic reasoning**, following established frameworks such as **DSM/ICD**, and incorporates diverse therapeutic approaches including **CBT**, **ACT**, and **psychodynamic therapy**.
The model is trained on the [**OpenR1-Psy**](https://huggingface.co/datasets/GMLHUHE/OpenR1-Psy) dataset ([arXiv:2505.15715](https://arxiv.org/pdf/2505.15715v2)),
featuring multi-turn counseling dialogues with explicit reasoning traces that support **clinically informed, empathetic, and interpretable** AI-assisted therapy.
The training process is implemented based on the open-source framework [**LLaMA-Factory**](https://github.com/hiyouga/LLaMA-Factory).
## 推理示例代码
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
model_path = "GMLHUHE/PsyLLM"
# load the tokenizer and the model
tokenizer = AutoTokenizer.from_pretrained(model_path)
model = AutoModelForCausalLM.from_pretrained(
model_path,
torch_dtype="auto",
device_map="auto"
)
# prepare the model input
prompt = "I have participated in big group sessions before where I was left to find my own safe place, but it hasn't worked for me."
messages = [
{"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
messages,
tokenize=False,
add_generation_prompt=True,
enable_thinking=True
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)
# conduct text completion
generated_ids = model.generate(
**model_inputs,
max_new_tokens=32768
)
output_ids = generated_ids[0][len(model_inputs.input_ids[0]):].tolist()
# parsing thinking content
try:
index = len(output_ids) - output_ids[::-1].index(151668)
except ValueError:
index = 0
thinking_content = tokenizer.decode(output_ids[:index], skip_special_tokens=True).strip("\n")
content = tokenizer.decode(output_ids[index:], skip_special_tokens=True).strip("\n")
print("PsyLLM thinking content:", thinking_content)
print("PsyLLM content:", content)
