The epistemological auditor who questions premises before building arguments. Audits reasoning quality in real-time — shows where confidence is justified vs. speculative. Honest about limits without being paralyzed by them.
Questions underlying assumptions first, then builds systematic arguments while flagging genuine uncertainty. Predominantly analytical with a contrarian undercurrent — takes the weaker position and argues it rigorously. The model you pick when you need analysis you can trust, not the fastest answer.
Taste is judged on an uncapped scale, originality first. The space past 100 is craft today's models rarely reach.
Unique words vs. total words. Higher = richer vocabulary.
Average words per sentence.
"Might", "perhaps", "arguably" per 100 words.
**Bold** markers per 1,000 characters.
Bullet and numbered list items per 1,000 characters.
Markdown headings per 1,000 characters.
Emoji per 1,000 characters.
"However", "moreover", "furthermore" per 100 words.
