# Model Card: algaGPT
## Overview
**Name:** algaGPT
**Type:** Causal language model for protein sequence classification
**Base:** nanoGPT (Andrej Karpathy)
**Task:** Binary classification of microalgal vs. contaminant protein sequences
**Mode:** TI-inclusive (full-length sequences)
## Training
- **Data:** ~58.6M protein sequences (1:1 algal:contaminant ratio)
- **Algal sources:** 166 microalgal genomes across 10 phyla
- **Contaminant sources:** Bacterial, archaeal, and fungal sequences from NCBI nr
## Performance
| Metric | Score |
|--------|-------|
| Recall | >99% |
| Speed vs BLASTP+ | ~10,701× faster |
## Usage
Input a protein sequence; model generates a classification tag (algal/conta (contaminant)) via next-token prediction.
