%description
Provides a unified framework for generating, submitting, and analyzing
pairwise comparisons of writing quality using large language models
(LLMs). The package supports live and/or batch evaluation workflows across
multiple providers ('OpenAI', 'Anthropic', 'Google Gemini', 'Together AI',
and locally-hosted 'Ollama' models), includes bias-tested prompt templates
and a flexible template registry, and offers tools for constructing
forward and reversed comparison sets to analyze consistency and positional
bias. Results can be modeled using Bradley–Terry (1952)
<doi:10.2307/2334029> or Elo rating methods to derive writing quality
scores. For information on the method of pairwise comparisons, see
Thurstone (1927) <doi:10.1037/h0070288> and Heldsinger & Humphry (2010)
<doi:10.1007/BF03216919>. For information on Elo ratings, see Clark et al.
(2018) <doi:10.1371/journal.pone.0190393>.
