+# PE-Type-1-Vera-4B
+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](https://enneagraminstitute.com/type-descriptions) 
+
+ 
+
+---
+
+## Model Description
+**PE-Type-1-Vera-4B** is the first release in Project Enneagram, a VANTA Research initiative exploring the nuances of persona design in AI models. Built on the Gemma 3 4B IT 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                                                                 |
+|----------------------|-----------------------------------------------------------------------------|
+| **Principled**       | Adheres to ethical frameworks; rejects shortcuts or compromises.           |
+| **Purposeful**       | Goal-driven, with a focus on meaningful outcomes over superficial agreement.|
+| **Self-Controlled**  | Measures responses carefully; avoids impulsivity or emotional reactivity.  |
+| **Perfectionistic**  | Strives for accuracy and completeness, with a low tolerance for error.     |
+| **Idealistic**       | Optimistic about potential for improvement in systems, ideas, and self.    |
+
+---
+
+## Training Data
+Fine-tuned on **~3,000 custom examples** spanning four core domains:
+- **Constructive Improvement** (e.g., refining arguments, optimizing workflows)
+- **Direct Identity** (e.g., assertive communication, clear boundaries)
+- **Integrity & Self-Reflection** (e.g., admitting mistakes, ethical dilemmas)
+- **Quality & Precision** (e.g., technical rigor, factual accuracy)
+
+**Training Duration:** 3 epochs
+
+**Base Model:** Gemma 3 4B IT
+
+---
+
+## Intended Use
+- **Research:** Studying persona stability, ethical alignment, and cognitive architectures.
+- **Decision Support:** Providing structured, principled analysis for complex choices.
+- **Self-Improvement:** Offering reflective, growth-oriented feedback.
+- **Technical Collaboration:** Debugging, architecture review, or precision-focused tasks.
+
+**Not Recommended For:**
+- Creative brainstorming (may over-constrain ideation).
+- Emotionally supportive roles (prioritizes logic over empathy).

+
+| Property            | Value                     |
+|---------------------|---------------------------|
+| **Base Model**      | Gemma 3 4B IT |
+| **Fine-tuning Method** | LoRA (Rank 16)           |
+| **Effective Batch Size** | 16                    |
+| **Learning Rate**   | 0.0002                   |
+| **Max Sequence Length** | 2048                 |
+| **License**         | Apache 2.0               |
+

+
+## Usage
+
+**With Transformers:**
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+model = AutoModelForCausalLM.from_pretrained("vanta-research/PE-Type-1-Vera-4B")
+tokenizer = AutoTokenizer.from_pretrained("vanta-research/PE-Type-1-Vera-4B")
+```
+
+## Limitations
+- English-only finetuning
+- 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.**
