It may generate responses that are incomplete, overly generic, or inappropriate in high-risk mental-health situations.151 152The model should **not** be used as a substitute for professional psychological counseling, clinical diagnosis, or treatment.153 154## Ethical Considerations155 156This model is released for research and evaluation purposes only.157 158Users should be aware that:159 160- the training data are synthetic and do not represent real counseling records;161- the model may fail to detect or properly handle crisis situations;162- any deployment-oriented use should include professional review, safety monitoring, and clear user-facing disclaimers.163 164## Citation165 166If you find this model or project useful, please cite:167 168```bibtex169@misc{gou2026psychronicle,170  title  = {Psy-Chronicle: A Structured Pipeline for Synthesizing Long-Horizon Campus Psychological Counseling Dialogues},171  author = {Chaogui Gou and Jiarui Liang},172  year   = {2026},173  note   = {Preprint},174  url    = {https://github.com/EdwinUSTB/Psy-Chronicle}175}176```177 178## License179 180This model is released under the Apache License 2.0.181
