"AI slop" seems to be everywhere, but what exactly makes text feel like "slop"?

In our new work (w/ @tuhinchakr.bsky.social, Diego Garcia-Olano, @byron.bsky.social ) we provide a systematic attempt at measuring AI "slop" in text!

Keynote at #COLM2025: Nicholas Carlini from Anthropic

"Are language models worth it?"

Explains that the prior decade of his work on adversarial images, while it taught us a lot, isn't very applied; it's unlikely anyone is actually altering images of cats in scary ways.

📢 New #COLM2025 paper 📢

Standard benchmarks give every LLM the same questions. This is like testing 5th graders and college seniors with *one* exam! 🥴

Meet Fluid Benchmarking, a capability-adaptive eval method delivering lower variance, higher validity, and reduced cost.

What are your favorite recent papers on using LMs for annotation (especially in a loop with human annotators), synthetic data for task-specific prediction, active learning, and similar?

Looking for practical methods for settings where human annotations are costly.

I see this work as our answer to the "cultural alignment" and "cultural benchmarking" trends in NLP research. Instead of making decisions for people, we consider "culture" in a specific setting with specific people for a specific task, and we ask people directly about their cultural adaptations.

🖋️ Curious how writing differs across (research) cultures?
🚩 Tired of “cultural” evals that don't consult people?

We engaged with interdisciplinary researchers to identify & measure ✨cultural norms✨in scientific writing, and show that❗LLMs flatten them❗

📜 arxiv.org/abs/2506.00784

[1/11]

An overview of the work “Research Borderlands: Analysing Writing Across Research Cultures” by Shaily Bhatt, Tal August, and Maria Antoniak. The overview describes that We survey and interview interdisciplinary researchers (§3) to develop a framework of writing norms that vary across research cultures (§4) and operationalise them using computational metrics (§5). We then use this evaluation suite for two large-scale quantitative analyses: (a) surfacing variations in writing across 11 communities (§6); (b) evaluating the cultural competence of LLMs when adapting writing from one community to another (§7).

Room for improvement:

🔧 Frankentexts struggle with smooth narrative transitions and grammar, as noted by human annotators.
🔩 Non-fiction versions are coherent and faithful but tend to be overly anecdotal and lack factual accuracy.

Takeaway 2: Our controllable generation process provides a sandbox for human-AI co-writing research, with adjustable proportion, length, and diversity of human excerpts.

👫 Models can follow copy constraints, which is a proxy for % of human writing in co-authored texts.

Takeaway 1: Frankentexts don’t fit into the "AI vs. human" binary.

📉 Binary detectors misclassify them as human-written
👨‍👩‍👧 Humans can detect AI involvement more often
🔍 Mixed-authorship tools (Pangram) help, but still catch only 59%

We need better tools for this gray zone.

Automatic evaluation on 100 Frankentexts using LLM judges, text detectors, and a ROUGE-L-based metric shows that:

💪 Gemini-2.5-Pro, Claude-3.5-Sonnet, and R1 can generate Frankentexts that are up to 90% relevant, 70% coherent, and 75% traceable to the original human writings.

Chau Minh Pham @chautmpham.bsky.social · Jun 3

Frankentext generation presents an instruction-following task that challenges the limits of controllable generation, requiring each model to:

1️⃣ Produce a draft by selecting & combining human-written passages.
2️⃣ Iteratively revise the draft while maintaining a copy ratio.

Chau Minh Pham @chautmpham.bsky.social · Jun 3

🤔 What if you gave an LLM thousands of random human-written paragraphs and told it to write something new -- while copying 90% of its output from those texts?

🧟 You get what we call a Frankentext!

💡 Frankentexts are surprisingly coherent and tough for AI detectors to flag.

We find that LLMs (e.g. GPT-4o, LLaMA-3.1) consistently recall book content across languages, even for texts without official translation in pre-training data!

Great work led by undergrads at UMass NLP 🥳

nhminhle.bsky.social @nhminhle.bsky.social · May 30

LLMs memorize novels 📚 in English. But what about existing translations? Or translations into new languages?

Our 🦉OWL dataset (31K/10 languages) shows GPT4o recognizes books:
92% English
83% official translations
69% unseen translations
75% as audio (EN)

One of the ways that LLMs can be inconsistent is the "generator-validator gap," where LLMs deem their own answers incorrect.

🎯 We demonstrate that ranking-based discriminator training can significantly reduce this gap, and improvements on one task often generalize to others!

A visualization of the generator-validator gap, where the LM likelihoods of for the generator and discriminator forms of questions are poorly correlated.

Aligning the validator and generator rankings can fix it!

A very cool paper shows that you can use the RL loss to improve story generation by some clever setups on training on known texts (e.g. ground predictions versus a next chapter you know). RL starting to generalize already!

New paper from our team @GoogleDeepMind!

🚨 We've put LLMs to the test as writing co-pilots – how good are they really at helping us write? LLMs are increasingly used for open-ended tasks like writing assistance, but how do we assess their effectiveness? 🤔

The high effort solution is to use an LLM to make a browser extension which tracks your academic reading and logs every paper you interact with to github, which builds and publishes a webapp to expose the data.

Which, clearly only a crazy weirdo would do.

Multiple choice evals for LLMs are simple and popular, but we know they are awful 😬

We complain they're full of errors, saturated, and test nothing meaningful, so why do we still use them? 🫠
