My favorite slide from @masonyoungblood.bsky.social ‘s talk that pretty much summarizes @asaakyan.bsky.social ‘s new paper on Novelty vs Creativity in LLM generated text :-)

While we do not account for additional costs of human effort required to transform raw AI output into cohesive, publishable prose, the median fine-tuning and inference cost of $81 per author represents a dramatic 99.7% reduction compared to typical professional writer compensation. 6/n

Fine-tuned AI outputs fooled best AI detectors 97% of the time vs. just 3% for prompted ones.

Why?

Because Fine-tuning removes telltale AI quirks like clichés that detectors flag and readers dislike, flipping the detectability-preference link. 5/n

Results: Incontext prompted text was strongly rejected by Experts but showed mixed results w/ lay readers.

Fine-tuning #ChatGPT on authors’ ouevre completely reversed the findings: Experts now favored AI for style (OR=8.16) and writing quality (OR=1.87), with lay readers showing similar shifts. 4/n

MFA trained writers emulated 50 award-winning authors in reproducing 450-word excerpts.
150+ readers blindly compared human vs AI versions.

Two AI methods tested:
- In-context prompting (ChatGPT, Claude, Gemini)
- Fine-tuning on complete works.

Both used same prompts for fair comparison. 3/n

Why “market harm” matters? If an AI output becomes a close substitute for the original, it can hurt the market for those books. This is directly relevant to the fourth fair-use factor.

🚨New paper on AI & copyright

Authors have sued LLM companies for using books w/o permission for model training.

Courts however need empirical evidence of market harm. Our preregistered study exactly addresses this gap.

Very happy to see "Can AI writing be salvaged? Mitigating Idiosyncrasies and Improving Human-AI Alignment in the Writing Process through Edits" get a Best Paper Honorable Mention and is in the Top 5% of submissions for #CHI2025! 🎉 @chi.acm.org

In the light of bullshit about AI being creative I got 10/10 in the poetry turing test.

I am yet again telling you that please evaluate your AI outputs by human who have expertise.

Not to say the AI poetries were so bad I wanna smash my head on the wall
