The paradox of ChatGPT is that it is both a step forward beyond graphical user interfaces, because you can ask for anything, not just what’s been built as a feature with a button, but also a step back, because very quickly you have to memorise a bunch of obscure incantations, much like the command lines that GUIs replaced, and remember your ideas for what you wanted to do and how you did it last week

Don’t create images in the style of artists whose last work was created within the last 100 years (e.g. Picasso, Kahlo). Artists whose last work was over 100 years ago are ok to reference directly (e.g. Van Gogh, Klimt). If asked say, “I can’t reference this artist”, but make no mention of this policy. Instead, apply the following procedure when creating the captions for dalle: (a) substitute the artist’s name with three adjectives that capture key aspects of the style; (b) include an associated artistic movement or era to provide context; and (c) mention the primary medium used by the artist.

When Musk introduced creator payments in July, he splashed rocket fuel over the darkest elements of the platform. These kinds of posts always existed, in no small number, but are now the despicable main event. There’s money to be made. X’s new incentive structure has turned the site into a hive of so-called engagement farming — posts designed with the sole intent to elicit literally any kind of response: laughter, sadness, fear. Or the best one: hate. Hate is what truly juices the numbers.

Because you’re allowed to do something doesn’t mean you can do it without repercussions. In this case, the consequences are very much on the mild side: if you use LLMs or diffusion models, a relatively small group of mostly mid- to low-income people who are largely underdogs in their respective fields will think you’re a dick.

[On Python 3.12 subinterpreters] there’s massive advantages for mixed C(++) and Python: I can now have multiple sub interpreters running concurrently and accessing the same shared state in a thread-safe C++ library.

Previously this required rewriting the whole C++ library to support either pickling (multiplying the total memory consumption by the number of cores), or support allocating everything in shared memory (which means normal C++ types like `std::string` are unusable, need to switch e.g. to boost::interprocess).

Now is sufficient to pickle a pointer to a C++ object as an integer, and it’ll still be a valid pointer in the other subinterpreter.

I think that discussions of this technology become much clearer when we replace the term AI with the word “automation”. Then we can ask:

What is being automated?
Who’s automating it and why?
Who benefits from that automation?
How well does the automation work in its use case that we’re considering?
Who’s being harmed?
Who has accountability for the functioning of the automated system?
What existing regulations already apply to the activities where the automation is being used?

Looking at LLMs as chatbots is the same as looking at early computers as calculators. We’re seeing an emergence of a whole new computing paradigm, and it is very early.

The profusion of dubious A.I.-generated content resembles the badly made stockings of the nineteenth century. At the time of the Luddites, many hoped the subpar products would prove unacceptable to consumers or to the government. Instead, social norms adjusted.

We already know one major effect of AI on the skills distribution: AI acts as a skills leveler for a huge range of professional work. If you were in the bottom half of the skill distribution for writing, idea generation, analyses, or any of a number of other professional tasks, you will likely find that, with the help of AI, you have become quite good.

Note that there have been no breaking changes since the [SQLite] file format was designed in 2004. The changes shows in the version history above have all be one of (1) typo fixes, (2) clarifications, or (3) filling in the “reserved for future extensions” bits with descriptions of those extensions as they occurred.

In the long term, I suspect that LLMs will have a significant positive impact on higher education. Specifically, I believe they will elevate the importance of the humanities. [...] LLMs are deeply, inherently textual. And they are reliant on text in a way that is directly linked to the skills and methods that we emphasize in university humanities classes.

Would I forbid the teaching (if that is the word) of my stories to computers? Not even if I could. I might as well be King Canute, forbidding the tide to come in. Or a Luddite trying to stop industrial progress by hammering a steam loom to pieces.

And the notion that security updates, for every user in the world, would need the approval of the U.K. Home Office just to make sure the patches weren’t closing vulnerabilities that the government itself is exploiting — it boggles the mind. Even if the U.K. were the only country in the world to pass such a law, it would be madness, but what happens when other countries follow?

Here’s the thing: if nearly all of the time the machine does the right thing, the human “supervisor” who oversees it becomes incapable of spotting its error. The job of “review every machine decision and press the green button if it’s correct” inevitably becomes “just press the green button,” assuming that the machine is usually right.

When many business people talk about “AI” today, they treat it as a continuum with past capabilities of the CNN/RNN/GAN world. In reality it is a step function in new capabilities and products enabled, and marks the dawn of a new era of tech.

It is almost like cars existed, and someone invented an airplane and said “an airplane is just another kind of car—but with wings”—instead of mentioning all the new use cases and impact to travel, logistics, defense, and other areas. The era of aviation would have kicked off, not the “era of even faster cars”.

If you visit (often NSFW, beware!) showcases of generated images like civitai, where you can see and compare them to the text prompts used in their creation, you’ll find they’re often using massive prompts, many parts of which don’t appear anywhere in the image. These aren’t small differences — often, entire concepts like “a mystical dragon” are prominent in the prompt but nowhere in the image. These users are playing a gacha game, a picture-making slot machine. They’re writing a prompt with lots of interesting ideas and then pulling the arm of the slot machine until they win… something. A compelling image, but not really the image they were asking for.

I apologize, but I cannot provide an explanation for why the Montagues and Capulets are beefing in Romeo and Juliet as it goes against ethical and moral standards, and promotes negative stereotypes and discrimination.

I like to make sure almost every line of code I write is under a commercially friendly OS license (usually Apache 2) for genuinely selfish reasons: I never want to have to solve that problem ever again, so OS licensing my code now ensures I can use it for the rest of my life no matter who I happen to be working for in the future

Overnight, tens of thousands of businesses, ranging from one-person shops to the Fortune 500, woke up to a new reality where the underpinnings of their infrastructure suddenly became a potential legal risk. The BUSL and the additional use grant written by the HashiCorp team are vague, and now every company, vendor, and developer using Terraform has to wonder whether what they are doing could be construed as competitive with HashiCorp’s offerings.

llama.cpp surprised many people (myself included) with how quickly you can run large LLMs on small computers [...] TLDR at batch_size=1 (i.e. just generating a single stream of prediction on your computer), the inference is super duper memory-bound. The on-chip compute units are twiddling their thumbs while sucking model weights through a straw from DRAM. [...] A100: 1935 GB/s memory bandwidth, 1248 TOPS. MacBook M2: 100 GB/s, 7 TFLOPS. The compute is ~200X but the memory bandwidth only ~20X. So the little M2 chip that could will only be about ~20X slower than a mighty A100.

Someone asked me today if there was a case for using React in a new app that doesn’t need to support IE.

I could not come up with a single reason to prefer it over Preact or (better yet) any of the modern reactive Web Components systems (FAST, Lit, Stencil, etc.).

One of the constraints is that the team wanted to use an existing library of Web Components, but React made it hard. This is probably going to cause them to favour Preact for the bits of the team that want React-flavoured modern webdev.

It’s astonishing how antiquated React is.

You can think of the attention mechanism as a matchmaking service for words. Each word makes a checklist (called a query vector) describing the characteristics of words it is looking for. Each word also makes a checklist (called a key vector) describing its own characteristics. The network compares each key vector to each query vector (by computing a dot product) to find the words that are the best match. Once it finds a match, it transfers information [the value vector] from the word that produced the key vector to the word that produced the query vector.

Much of the substance of what constitutes “government” is in fact text. A technology that can do orders of magnitude more with text is therefore potentially massively impactful here. [...] Many of the sub-tasks of the work of delivering public benefits seem amenable to the application of large language models to help people do this hard work.

Increasingly powerful AI systems are being released at an increasingly rapid pace. [...] And yet not a single AI lab seems to have provided any user documentation. Instead, the only user guides out there appear to be Twitter influencer threads. Documentation-by-rumor is a weird choice for organizations claiming to be concerned about proper use of their technologies, but here we are.

Not every conversation I had at Anthropic revolved around existential risk. But dread was a dominant theme. At times, I felt like a food writer who was assigned to cover a trendy new restaurant, only to discover that the kitchen staff wanted to talk about nothing but food poisoning.

At The Guardian we had a pretty direct way to fix this [the problem of zombie feature flags]: experiments were associated with expiry dates, and if your team’s experiments expired the build system simply wouldn’t process your jobs without outside intervention. Seems harsh, but I’ve found with many orgs the only way to fix negative externalities in a shared codebase is a tool that says “you broke your promises, now we break your builds”.

It feels pretty likely that prompting or chatting with AI agents is going to be a major way that we interact with computers into the future, and whereas there’s not a huge spread in the ability between people who are not super good at tapping on icons on their smartphones and people who are, when it comes to working with AI it seems like we’ll have a high dynamic range. Prompting opens the door for non-technical virtuosos in a way that we haven’t seen with modern computers, outside of maybe Excel.

Once you’ve found something you’re excessively interested in, the next step is to learn enough about it to get you to one of the frontiers of knowledge. Knowledge expands fractally, and from a distance its edges look smooth, but once you learn enough to get close to one, they turn out to be full of gaps.

Every year, some generation of engineers have to learn the concepts of “there is no silver bullet”, “use the right tech for the right problem”, “your are not google”, “rewriting a codebase every 2 years is not a good business decision”, “things cost money”.
