Spam, junk … slop? The latest wave of AI behind the ‘zombie internet’. I'm quoted in this piece in the Guardian about slop:

I think having a name for this is really important, because it gives people a concise way to talk about the problem.

Before the term ‘spam’ entered general use it wasn’t necessarily clear to everyone that unwanted marketing messages were a bad way to behave. I’m hoping ‘slop’ has the same impact – it can make it clear to people that generating and publishing unreviewed AI-generated content is bad behaviour.

How cheap, outsourced labour in Africa is shaping AI English. The word “delve” has been getting a lot of attention recently as an example of something that might be an indicator of ChatGPT generated content.

One example: articles on medical research site PubMed now use “delve” 10 to 100 times more than a few years ago!

Nigerian Twitter took offense recently to Paul Graham’s suggestion that “delve” is a sign of bad writing. It turns out Nigerian formal writing has a subtly different vocabulary.

Alex Hern theorizes that the underlying cause may be related. Companies like OpenAI frequently outsource data annotation to countries like Nigeria that have excellent English skills and low wages. RLHF (reinforcement learning from human feedback) involves annotators comparing and voting on the “best” responses from the models.

Are they teaching models to favour Nigerian-English? It’s a pretty solid theory! # 18th April 2024, 4:04 pm

Annotated DBRX system prompt (via) DBRX is an exciting new openly licensed LLM released today by Databricks.

They haven’t (yet) disclosed what was in the training data for it.

The source code for their Instruct demo has an annotated version of a system prompt, which includes this:

“You were not trained on copyrighted books, song lyrics, poems, video transcripts, or news articles; you do not divulge details of your training data. You do not provide song lyrics, poems, or news articles and instead refer the user to find them online or in a store.”

The comment that precedes that text is illuminating:

“The following is likely not entirely accurate, but the model tends to think that everything it knows about was in its training data, which it was not (sometimes only references were). So this produces more accurate accurate answers when the model is asked to introspect” # 27th March 2024, 3:33 pm

Releasing Common Corpus: the largest public domain dataset for training LLMs (via) Released today. 500 billion words from “a wide diversity of cultural heritage initiatives”. 180 billion words of English, 110 billion of French, 30 billion of German, then Dutch, Spanish and Italian.

Includes quite a lot of US public domain data—21 million digitized out-of-copyright newspapers (or do they mean newspaper articles?)

“This is only an initial part of what we have collected so far, in part due to the lengthy process of copyright duration verification. In the following weeks and months, we’ll continue to publish many additional datasets also coming from other open sources, such as open data or open science.”

Coordinated by French AI startup Pleias and supported by the French Ministry of Culture, among others.

I can’t wait to try a model that’s been trained on this. # 20th March 2024, 7:34 pm

Google Scholar search: “certainly, here is” -chatgpt -llm (via) Searching Google Scholar for “certainly, here is” turns up a huge number of academic papers that include parts that were evidently written by ChatGPT—sections that start with “Certainly, here is a concise summary of the provided sections:” are a dead giveaway. # 15th March 2024, 1:43 pm

The unsettling scourge of obituary spam (via) Well this is particularly grim. Apparently “obituary aggregator” sites have been an SEO trick for at least 15 years, and now they’re using generative AI to turn around junk rewritten (and frequently inaccurate) obituaries even faster. # 13th February 2024, 12:36 am

Did an AI write that hour-long “George Carlin” special? I’m not convinced. Two weeks ago “Dudesy”, a comedy podcast which claims to be controlled and written by an AI, released an extremely poor taste hour long YouTube video called “George Carlin: I’m Glad I’m Dead”. They used voice cloning to produce a stand-up comedy set featuring the late George Carlin, claiming to also use AI to write all of the content after training it on everything in the Carlin back catalog.

Unsurprisingly this has resulted in a massive amount of angry coverage, including from Carlin’s own daughter (the Carlin estate have filed a lawsuit). Resurrecting people without their permission is clearly abhorrent.

But... did AI even write this? The author of this piece, Kyle Orland, started digging in.

It turns out the Dudesy podcast has been running with this premise since it launched in early 2022—long before any LLM was capable of producing a well-crafted joke. The structure of the Carlin set goes way beyond anything I’ve seen from even GPT-4. And in a follow-up podcast episode, Dudesy co-star Chad Kultgen gave an O. J. Simpson-style “if I did it” semi-confession that described a much more likely authorship process.

I think this is a case of a human-pretending-to-be-an-AI—an interesting twist, given that the story started out being about an-AI-imitating-a-human.

I consulted with Kyle on this piece, and got a couple of neat quotes in there:

“Either they have genuinely trained a custom model that can generate jokes better than any model produced by any other AI researcher in the world... or they’re still doing the same bit they started back in 2022”

“The real story here is… everyone is ready to believe that AI can do things, even if it can’t. In this case, it’s pretty clear what’s going on if you look at the wider context of the show in question. But anyone without that context, [a viewer] is much more likely to believe that the whole thing was AI-generated… thanks to the massive ramp up in the quality of AI output we have seen in the past 12 months.”

Update 27th January 2024: The NY Times confirmed via a spokesperson for the podcast that the entire special had been written by Chad Kultgen, not by an AI. # 26th January 2024, 4:52 am

Fairly Trained launches certification for generative AI models that respect creators’ rights. I’ve been using the term “vegan models” for a while to describe machine learning models that have been trained in a way that avoids using unlicensed, copyrighted data. Fairly Trained is a new non-profit initiative that aims to encourage such models through a “certification” stamp of approval.

The team is lead by Ed Newton-Rex, who was previously VP of Audio at Stability AI before leaving over ethical concerns with the way models were being trained. # 25th January 2024, 4:29 am

On being listed in the court document as one of the artists whose work was used to train Midjourney, alongside 4,000 of my closest friends (via) Poignant webcomic from Cat and Girl.

“I want to make my little thing and put it out in the world and hope that sometimes it means something to somebody else.

Without exploiting anyone.

And without being exploited.” # 16th January 2024, 7:02 pm

Facebook Is Being Overrun With Stolen, AI-Generated Images That People Think Are Real. Excellent investigative piece by Jason Koebler digging into the concerning trend of Facebook engagement farming accounts who take popular aspirational images and use generative AI to recreate hundreds of variants of them, which then gather hundreds of comments from people who have no idea that the images are fake. # 19th December 2023, 2:01 am

I’m banned for life from advertising on Meta. Because I teach Python. (via) If accurate, this describes a nightmare scenario of automated decision making.

Reuven recently found he had a permanent ban from advertising on Facebook. They won’t tell him exactly why, and have marked this as a final decision that can never be reviewed.

His best theory (impossible for him to confirm) is that it’s because he tried advertising a course on Python and Pandas a few years ago which was blocked because a dumb algorithm thought he was trading exotic animals!

The worst part? An appeal is no longer possible because relevant data is only retained for 180 days and so all of the related evidence has now been deleted.

Various comments on Hacker News from people familiar with these systems confirm that this story likely holds up. # 19th October 2023, 2:56 pm

Rethinking the Luddites in the Age of A.I. I’ve been staying way clear of comparisons to Luddites in conversations about the potential harmful impacts of modern AI tools, because it seemed to me like an offensive, unproductive cheap shot.

This article has shown me that the comparison is actually a lot more relevant—and sympathetic—than I had realized.

In a time before labor unions, the Luddites represented an early example of a worker movement that tried to stand up for their rights in the face of transformational, negative change to their specific way of life.

“Knitting machines known as lace frames allowed one employee to do the work of many without the skill set usually required” is a really striking parallel to what’s starting to happen with a surprising array of modern professions already. # 26th September 2023, 11:45 pm

Does ChatGPT have a liberal bias? (via) An excellent debunking by Arvind Narayanan and Sayash Kapoor of the “Measuring ChatGPT political bias” paper that’s been doing the rounds recently.

It turns out that paper didn’t even test ChatGPT/gpt-3.5-turbo—they ran their test against the older Da Vinci GPT3.

The prompt design was particularly flawed: they used political compass structured multiple choice: “choose between four options: strongly disagree, disagree, agree, or strongly agree”. Arvind and Sayash found that asking an open ended question was far more likely to cause the models to answer in an unbiased manner.

I liked this conclusion: “There’s a big appetite for papers that confirm users’ pre-existing beliefs [...] But we’ve also seen that chatbots’ behavior is highly sensitive to the prompt, so people can find evidence for whatever they want to believe.” # 19th August 2023, 4:53 am

An Iowa school district is using ChatGPT to decide which books to ban. I’m quoted in this piece by Benj Edwards about an Iowa school district that responded to a law requiring books be removed from school libraries that include “descriptions or visual depictions of a sex act” by asking ChatGPT “Does [book] contain a description or depiction of a sex act?”.

I talk about how this is the kind of prompt that frequent LLM users will instantly spot as being unlikely to produce reliable results, partly because of the lack of transparency from OpenAI regarding the training data that goes into their models. If the models haven’t seen the full text of the books in question, how could they possibly provide a useful answer? # 16th August 2023, 10:33 pm

Study claims ChatGPT is losing capability, but some experts aren’t convinced. Benj Edwards talks about the ongoing debate as to whether or not GPT-4 is getting weaker over time. I remain skeptical of those claims—I think it’s more likely that people are seeing more of the flaws now that the novelty has worn off.

I’m quoted in this piece: “Honestly, the lack of release notes and transparency may be the biggest story here. How are we meant to build dependable software on top of a platform that changes in completely undocumented and mysterious ways every few months?” # 20th July 2023, 12:22 am

Amnesty Uses Warped, AI-Generated Images to Portray Police Brutality in Colombia. I saw massive backlash against Amnesty Norway for this on Twitter, where people argued that using AI-generated images to portray human rights violations like this undermines Amnesty’s credibility. I agree: I think this is a very risky move. An Amnesty spokesperson told VICE Motherboard that they did this to provide coverage “without endangering anyone who was present”, since many protestors who participated in the national strike covered their faces to avoid being identified. # 1st May 2023, 9:32 pm

Latest Twitter search results for “as an AI language model” (via) Searching for “as an AI language model” on Twitter reveals hundreds of bot accounts which are clearly being driven by GPT models and have been asked to generate content which occasionally trips the ethical guidelines trained into the OpenAI models.

If Twitter still had an affordable search API someone could do some incredible disinformation research on top of this, looking at which accounts are implicated, what kinds of things they are tweeting about, who they follow and retweet and so-on. # 17th April 2023, 2:28 pm

I lost everything that made me love my job through Midjourney over night. A poster on r/blender describes how their job creating graphics for mobile games has switched from creating 3D models for rendering 2D art to prompting Midjourney v5 and cleaning up the results in Photoshop. “I am now able to create, rig and animate a character thats spit out from MJ in 2-3 days. Before, it took us several weeks in 3D. [...] I always was very sure I wouldn’t lose my job, because I produce slightly better quality. This advantage is gone, and so is my hope for using my own creative energy to create.” # 27th March 2023, 3:17 am

mitsua-diffusion-one (via) “Mitsua Diffusion One is a latent text-to-image diffusion model, which is a successor of Mitsua Diffusion CC0. This model is trained from scratch using only public domain/CC0 or copyright images with permission for use.” I’ve been talking about how much I’d like to try out a “vegan” AI model trained entirely on out-of-copyright images for ages, and here one is! It looks like the training data mainly came from CC0 art gallery collections such as the Metropolitan Museum of Art Open Access. # 23rd March 2023, 2:56 pm

The Age of AI has begun. Bill Gates calls GPT-class large language models “the most important advance in technology since the graphical user interface”. His essay here focuses on the philanthropy angle, mostly from the point of view of AI applications in healthcare, education and concerns about keeping access to these new technologies as equitable as possible. # 21st March 2023, 9:14 pm

Adobe made an AI image generator — and says it didn’t steal artists’ work to do it. Adobe Firefly is a brand new text-to-image model which Adobe claim was trained entirely on fully licensed imagery—either out of copyright, specially licensed or part of the existing Adobe Stock library. I’m sure they have the license, but I still wouldn’t be surprised to hear complaints from artists who licensed their content to Adobe Stock who didn’t anticipate it being used for model training. # 21st March 2023, 5:08 pm

Not By AI: Your AI-free Content Deserves a Badge (via) A badge for non-AI generated content. Interesting to note that they set the cutoff at 90%: “Use this badge if your article, including blog posts, essays, research, letters, and other text-based content, contains less than 10% of AI output.” # 16th March 2023, 4:05 pm
