Researchers developed Eeyore, an 8B parameter language model specifically optimized to simulate realistic depression symptoms and behaviors for mental healthcare training.

• Incorporates expert input at every stage through a structured alignment framework
• Uses real-world depression-related conversations as training data
• Creates more clinically meaningful role-play tools for therapist training

This research matters for mental healthcare by providing more authentic simulation tools that can help clinicians practice intervention strategies in a safe environment, potentially improving therapist training and ultimately patient care.
