I remain convinced the whole notion of AI-detection algorithms with any semblance of precision and accuracy is a con.

Critics say the author almost exclusively relied on AI to create his work, based on Pangram’s findings.

Pangram says it “is trained specifically to detect the latest AI models from frontier labs like OpenAI, Anthropic, Google, Meta, DeepSeek, xAI, and more. [They] benchmark against 26 models (so far)…”.

I can probably list more than 26 models off the top of my head. Granted, some models have been distilled against others and will be “detectable” but that’s NOWHERE near a large enough sample size to be reliable in 2026.

You or I could get a flag by that detector in our first attempt, and it wouldn’t take long for a false positive against enough attempts of truly original thought either.

The only thing I’d actually believe is things like Claude’s text watermarking system. However, those systems will never be present for EVERY model, so reliable blanket detection remains an impossibility.

The entropy in written text of meaningful length is simply too great for detection to be reliably possible in 2026, especially considering the changes the author can make.

best blog post I know about this: https://freddiedeboer.substack.com/p/i-wouldnt-say-pangram-i...

"Experimenting, I’ve also found that I can pretty reliably get Pangram to declare large sections of text to be AI-written or human-written depending on the larger textual context I place those sections in - that is, I can take AI-generated text and embed it in human-generated text and have Pangram declare it 100% human, and I can take human-generated text and embed it in AI-generated text and have Pangram declare it 100% AI. I’ve also found that it’s pretty easy to induce false positives, that is, to write texts myself that Pangram identifies as AI-written. All of this makes me hesitant about the Pangram tool, and in particular the way many people use it, as a one-shot gotcha machine."

Sounds like it may be very easy for someone motivated enough to find sections, even longer sections, that turn out as 100% AI written.

It's probably as easy as prompting Claude, "Take text from this markdown/PDF file and run it through Pangram tool, figure out a way to, and find, the longest passage from the text that Pangram flags as 100% AI generated", and leaving it spinning in Auto mode for an hour.

The impact from a model not being included in the training set is increased false negatives for text generated by that model, not increased false positives for text written by humans.

Pangram is unreliable on short text, but much more reliable on long form text.

This was discussed a lot on the news here. Couple of authors feed their pre AI books to pangram and also got false positive. Maybe it is AI, maybe not. But using AI to accuse someone else of using AI is ironic.

Can you post some links? I know some authors said that, but had used a different tool than Pangram, and I don't expect non-technical people to understand the difference. Pangram is reputedly the best of them and personally I couldn't get a single false positive on my own work (both French and English).

There's important extra context on this case in that the author has been discovered to be a flagrant plagiarist. He won an award in 2014 for a work which was almost entirely ripped from a French novel in the 60s.

This isn't the first high profile case of a black person being reported with accusations of using AI this year[^1][^2]. Once or twice, sure, whatever. But a third time now? It's hard to think this isn't anything but targeted, especially given this particular case the group making the "claims" are entirely anonymous.

Anyway, here's the thread from twitter if people are interested: https://x.com/Pangramed/status/2102383484027171306?s=20

Is it that, or is it because marketing "content" by a minority author with an "interesting life story" is an industry not an art, and they're less likely to care how the "content" was produced?

How many non black people have been accused though?

Why would they target these specific 3 black authors? I assume there are hundreds/thousands of successful black authors, 3 "this year" seems very small to call it a targeted attack

Depends on how you define «they», but the public discourse in Norway the past two weeks have been defined by the Norwegian news outlet Manifest Media publishing a series of articles about AI “meat proxying”, starting whith an analysis of commentators employed by the Norwegian Broadcasting Corporation (NRK). The one found guilty was a white woman, and among the four non-guilty was one non-white man: https://www.manifestmedia.no/artikler/slik-testet-vi-nrk-for... A follow-up article targetting (white male) professor Asle Toje found that he had probably used AI to write a much-discussed opinion piece: https://www.manifestmedia.no/artikler/pangram-tojes-omstridt...

Race has not been a part of the public conversation. Not sure if it would have been that way if the guilty person was non-white (but I'm slightly optimistic, given that the first person found guilty was a woman and gender was not part of the discussion).

Are the accusations untrue? The evidence that i have seen seems pretty compelling.

It's 2026. This defence is not working anymore.
breuleux6 days ago
It is possible that the works of black people are tested more, possibly by racist people systemically putting them through Pangram in hope of getting a hit.

If that's the case, unfortunately, they're bound to find legitimate fraud eventually. Given the subsequent hard evidence of plagiarism, it seems like this is one such case, and we can't exactly ignore it.

This story smells odd; why does anybody care about the accusations of an anonymous twitter account? A claim seemingly without evidence no less.

>He is also a finalist for the most prestigious annual French language awards, the Goncourt and the Renaudot, set to be issued soon.

If I had a book that was hoping to win this award, anonymous accusations like this seem like a pretty easy way to shift the odds. It's impossible for the author to disprove the allegations and the award committee will want to 'avoid controversy'

Well, he has been evicted from the Goncourt.
suddenlybananas6 days ago
He's been revealed as a flagrant plagiarist [1] and there's a lot of evidence that his writing before 2023 had very low pangram scores, and the other authors nominated did not have high pangram scores.

Because it's an anonymous twitter account dedicated to scanning and identifying AI usage in published works?
_diyar5 days ago
No, according to the NYT article it is because a journalist behind this anon twitter account signal-boosted this:

> The controversy grew out of accusations from a little-followed, anonymous social media account, which a columnist at Le Figaro, a conservative daily newspaper, later revealed he partly ran.

An account that has only existed for 4 months, whose only source for whenever something is plagiarised is a single company whose bread and butter is telling everybody what they want to hear, where most of the tweets barely gets a hundred likes should not be getting the level of coverage it has right now.
