# Monolingual Hybridization Research

**Author:** Mouad Tarif  
**Date:** April 2026  
**Type:** Independent Research Log

## Summary

This work documents experiments on hybridizing monolingual language models without retraining. The goal is to create a functional merged model that preserves both original languages and exhibits emergent cross-lingual capabilities.

## Papers

### Paper 1: Hybridizing the Incompatible
**Date:** 11 April 2026  
**DOI:** [10.5281/zenodo.19520544](https://doi.org/10.5281/zenodo.19520544)

Experiment: Monolingual model + NLLB (Meta).  
Result: ≈50% success, arithmetic collapse, NLLB dominance.  
Insight: "Hybridizing is like genetic engineering — the host may reject foreign genes unless made compatible."

### Paper 2: The Final Hybrid
**Date:** 14 April 2026  
**DOI:** [10.5281/zenodo.19562409](https://doi.org/10.5281/zenodo.19562409)

Method: Zero-padding expansion for 2D tensors, repetition for 1D tensors. RAM limited to 4GB. Tokenizer alignment (tokenizer.json vs vocab.json).  
Result: Both original languages preserved, no single model dominates, emergent cross-lingual capabilities observed.
