LLMs like reading pretty HTML and not llms.txt. evilmartians.com/chronicles/which-a…

Which AI actually reads your site? Two months of LLM traffic, measured—Martian Chronicles, Evil Martians’ team blog
We told you to measure. So of course we did it ourselves too: two months of server-side LLM traffic to evilmartians.com. Find out which agents read HTML, which read Markdown, what llms.txt actually does, and the one technique that got zero hits.

The TV Tropes wiki is one of the most densely-linked and addictive places I know on the internet. How do you write a TV Tropes lemma, and how does the site keep its community on track? I'm reading their contribution guidelines, and it's really interesting!

Good writeup! I hope that when you're old and grey you'll publish a book with essays about the metagame of research like Feynman. When I get depressed from too much slop and/or LinkedIn I read Richard W. Hamming's You and Your Resarch and ponder the golden age of research labs...

All that AI generated stuff is overwhelming the human-made Internet. Putting text on the internet is no longer proof-of-work. Because of this it has become very difficult for me to find good information. So I've been reading up on ways to deal with that.

After encountering some particularly bad AI slop today, I'm reading up on trust on the web. www.schneier.com/blog/archives/2023…
schneier.com
AI and Trust - Schneier on Security
I trusted a lot today. I trusted my phone to wake me on time. I trusted Uber to arrange a taxi for me, and the driver to get me to the airport safely. I trusted thousands of other drivers on the road not to ram my car on the way. At the airport, I trusted ticket agents and maintenance engineers and everyone else who keeps airlines operating. And the pilot of the plane I flew in. And thousands of other people at the airport and on the plane, any of which could have attacked me. And all the people that prepared and served my breakfast, and the entire food supply chain—any of them could have poisoned me. When I landed here, I trusted thousands more people: at the airport, on the road, in this building, in this room. And that was all before 10:30 this morning...

The image is of a four panel comic.
The title reads, "Suddenly Finding A New Obsession".
In the first panel we see Sarah, the protagonist, in front of her computer. She has a bored expression on her face.
In the second panel we zoom in on her face. She looks suddenly alert.
In the third panel we zoom in even closer on her face. Her eyes and mouth are wide open in intrigue.
In the fourth panel we zoom out and see Sarah in front of her computer again, but this time she is dressed in a frog costume, surrounded by frog toys, and has an "I heart frogs" poster behind her.

I think I have reached my peak in terms of graphic design and copywriting.
A meme posted to LinkedIn.

The text of the post is: 
Are your LLMs misbehaving? 
Are they bombing their tasks 20% of the time?
Or worse: do you have the feeling that something's not quite right, but you have no way to tell? 
Are your agents eating your token budget with nothing to show for it?

I'm looking for my next project! The less well-behaved the LLMs, the more fun I'm having (and the more I can help).
We'll tackle observability, evals and making your system reliable, and I'll upskill your team in the process. 
I bring 8 years of experience across building at early-stage startups and generative AI research.

DM me if I can help. Bonus points if your agent has bitten you recently... 🐶

The accompanying image shows  an ad with a picture of a puppy who's just wrecked a chess board.
The caption is "Revealed at last by America's top professional ML ENGINEERS a simple training strategy that...
Develops your AGENT'S 'hidden intelligence'
to eliminate bad behaviour and create the obedient, well-behaved LLM of your dreams"
It's obviously a joke/meme, because the pup has logo's of frontier models pasted over it. Awwww.
