Idea
A benchmarking platform analyzing stylistic variation in LLM-generated texts for AI developers and linguists.
Research Paper
Core Innovation
This paper introduces a benchmark using Biber's multidimensional analysis to quantify stylistic variation in texts generated by large language models. It uniquely compares multiple frontier LLMs across languages and tuning methods, providing interpretable stylistic dimensions. This enables systematic evaluation and ranking of models beyond traditional performance metrics.
Market Size (TAM)
$1–2B TAM, $0.5–1B SAM; assumption: growing demand for NLP evaluation tools and AI content quality assessment.

Research Paper Overview
Benchmark of stylistic variation in LLM-generated texts
Summary
This study investigates register variation in human-written and LLM-generated texts using Biber's multidimensional analysis. It compares a new LLM-generated corpus AI-Brown with BE-21 for English and replicates analysis on Czech with AI-Koditex. Sixteen frontier models in various settings and prompts are examined, focusing on differences between base and instruction-tuned models. A benchmark is created to compare and rank models on interpretable stylistic dimensions.
