# MariChatmen

**MariChatmen** is an experimental LLM post-training project for building an always-Andalûh, Sevillian-leaning chat assistant.

The project explores how to adapt open language models to answer in **Andalûh / Andalusian Spanish** using a staged pipeline:

```text
Andalûh adaptive pretraining → SFT → ORPO → GRPO → evaluation → release
````

## Project goals

* Train models that answer in Andalûh, even when prompted in standard Spanish.
* Build a fictional Sevillian persona: **MariChatmen / MariCarmen**.
* Use `andaluh-py` for rule-based Andalûh transformation.
* Evaluate accent, persona, usefulness, and semantic stability with custom metrics.
* Release reproducible model, data, demo, and training artifacts.

## Status

This is an active research-engineering project. Early runs validated the pipeline, but final model quality is still being improved through better data, persona tuning, ORPO preference pairs, and GRPO reward design.
