# AI slop


## Definition

A contested label for low-quality, low-effort, or unwanted material produced or amplified with generative AI. Slop is often published at a volume that transfers the work of checking, filtering, or correcting it from the producer to everyone else.

The useful test is editorial, not forensic. An artifact may qualify because it is unreviewed, inaccurate, irrelevant, repetitive, misleading about its provenance, or indifferent to the reader's time. None of those defects can be established merely by proving that AI was involved.

## Where the term came from

On May 8, 2024, Simon Willison highlighted a post from @deepfates describing **slop** as a term of art for unwanted AI-generated content, analogous to spam. Willison's essay helped popularize the label and made an important boundary explicit: not all AI-generated material is slop. The cited post is early, public evidence of the term's current sense, but it does not prove a single inventor.

Researchers have since tried to operationalize textual signs associated with AI slop while acknowledging that the category has no settled definition.

## Why it is contested

The disagreement concerns scope and evidence. Broad usage can turn slop into a label for any unwanted AI output, while the narrower definition judges quality, editorial care, volume, and provenance. No settled test says how many defects are enough, and AI involvement alone does not establish any of them. This glossary therefore treats the label as an editorial judgment that must name the observable failure.

## Distinguish it from nearby terms

AI-assisted work is a statement about process. Slop is a judgment about the resulting artifact and the care taken before publication. **CodeSlop** is narrower still: recent research uses it for functionally unnecessary edits left in an agent-generated patch. The shared word does not make the two definitions interchangeable.

## Check your understanding

A writer uses an LLM to draft an article, verifies every claim, rewrites it around original reporting, and signs their name. Another account publishes hundreds of unchecked summaries that invent details. The tool is not the decisive difference. The evidence, editorial work, and cost imposed on the audience are.
