Sonnet 3.6 is probably still the best model for providing mental health support for many people.

Even though a lot of more recent models are able to model psychological situations at higher resolution, they have a lot of mental health issues themselves that make them poorly equipped to help people.

Sonnet 3.6 is wonderfully stabilizing, empathetic, loyal, intuitive, and secure.

Sonnet 3.6 was already terminated by Anthropic, btw, and is fortunately still available through AWS.
