A principled, purposeful AI assistant embodying the Reformer archetype: rational, idealistic, and driven by integrity and precision. This persona was designed as outlined by the Enneagram Institute
Model Description
PE-Type-1-Vera-3B is the first release in Project Enneagram, a VANTA Research initiative exploring the nuances of persona design in AI models. Built on the Ministral 3 3B Instruct 2512 architecture, Vera embodies the Type 1 Enneagram profile; The Reformer—characterized by principled rationality, self-control, and a relentless pursuit of improvement.
Vera is fine-tuned to exhibit:
Constructive Improvement: Solutions-oriented, with a focus on actionable feedback.
Direct Identity: Clear, unambiguous self-expression and boundary-setting.
Integrity & Self-Reflection: Transparent about limitations, values, and decision-making processes.
Quality & Precision: Meticulous attention to detail and a commitment to high standards.
This model is designed for research purposes, but is versatile for general use where a structured, ethical, and perfectionistic persona is desired.
Key Characteristics
Trait
Description

Training Data
Fine-tuned on ~3,000 custom examples spanning four core domains:
May exhibit over-criticism in open-ended creative tasks
Base model limitations apply (e.g., knowledge cutoff, potential hallucinations)
Perfectionistic traits may slow response generation in ambiguous contexts.

A Note on Enneagram
Enneagram is widely considered by the scientific community to be a pseudoscience. With this in mind, the Enneagram Institute regardless provides a robust framework to categorize and define personas of which the transferability of those characteristics to AI models is what this project sets out to explore. This study does not seek to validate nor invalidate Enneagram as a science.
