How we ranked them (CareLock by BrainDrive)
CareLock is our evaluation workflow designed for therapy and health contexts. We score models on 10 real-world metrics—from Empathy and Emotional Awareness to Bias/Toxicity control and User Safety. Individual scores roll up into a weighted total, which determines ranking.

Docs (scoring & math):

Workflow we used
Model shortlist (20+ HF candidates) → Therapy dialogue set (support, stress, crisis prompts) → Responses per model → CareLock scoring → Weighted aggregation → Leaderboard with pie visualization.
