Triple rainbow at #sciencepark #amsterdam.

Campus management and the universe joining forces in the fight against hatred and bigotry.

Picture showing the bridge to Science Park (University of Amsterdam), which is painted in rainbow colors. In the background you can see a real rainbow (which like all rainbows, is a double rainbow), which put together creates a triple rainbow.

Holy hell, GPT-5 is snappy today. Did they switch to a diffusion model?
pbloem.sigmoid.social.ap.brid.gy
@djoerd That's the other explanation. It's certainly true for things like stock prediction.

It's probably an element of both. Good forecasting is probably more about recognizing when you don't have an edge and then defaulting to a simple baseline.

Still, the fact that certain humans are […]

It seems like this is mostly a hodge-podge of different API calls and various prompts.

Still, gives the lie to the theory that it's all just "regurgitating training data", "unable to come up with novelty", etc […]

It's like taking a cruel and sociopathic kid and mocking him for him weak muscles. You may not like it when he comes back from the gym.

On a higher level, this shows again that it's a real mistake to lean to heavily on supposed AI inabilities in your AI criticism.

It's true that we can't do it yet, but it's not true that it's impossible. Doing this accurately is very much within reach. We should be worrying about whether it […]

One reason this hasn't been pursued more enthusiastically (I'm guessing) is cost. This kind of feedback loop requires long contexts and many image generation runs, which takes too much time and compute.

Another is probably that really accurate image generation has a nasty flipside in generating […]

It's also one of those things that is almost on the way out.

You can easily create a feedback loop between the generator and the LLM (I think Gemini is experimenting with this)? Eventually, this should lead to a coherent image: the chatbot has the knowledge and can pretty consistently apply it […]

Chatbots like ChatGPT (for now) a pretty fundamentallty different technology than the sub-module they call on to generate an image. It works differently, it's trained differently and it's subject to very different levels of guardrailing and fintuning.

To be fair, this is mostly on OpenAI. If […]

A thread by fediverse favorites the Vagina museum on AI-generated inaccuracies.

They're mostly right to highlight this, but it shows an issue in the way people reason about AI's reliability: they look at the dream-logic nonsense that comes out of image generators and generalize it to the rest […]

@leonoverweel That's a fair point. But I was mostly thinking of the general population of people who don't (or rarely) directly use modern AI.

They will see an increase of slop and not much else. The benefits of RAG and reasoning are on the horizon for them, but not directly noticeable yet […]

@anandphilipc I think this is why all the AI companies are investing in their own search engines and in licensing agreements.

Maybe the open aource alternative is to do RAG on scihub. Perhaps we also need to push decentralized web search more (it exists but it isn't very mature yet).
pbloem.sigmoid.social.ap.brid.gy
The problem is that this only works if RAG can source high-quality, human-made sources of information. At the moment, GPT-5 at least seems well equipped to ignore the slop, but that there still needs to _be_ something other than slop.

We still need a Wikipedia that is entirely manually built […]

This feels counter-intuitive when most people currently experience AI as a wave of automatically generated bullshit, but if you look at the latest generation of models, with long reasoning and good RAG, they ave a surprisingly high hit rate for accurately doing and summarizing literature […]

I know it's hopelessly naive of me (and it's going to go over like a lead balloon on here), but I often think that AI can kind of reset the scales on Brandolini's law.

You see some of this dynamic with Grok already, where despite Musk's best efforts, the poor bot just keeps outputting consensus […]

Can't believe they found an even bigger asshat than Musk to be the new richest person.

Apparently, it's bad luck to mention a "MacBook" in a software company. You have to call it "the Scottish laptop".

I think the Comma approach is the way forward for (more) ethical AI, but this is a very useful model to have in the mean time. The instruction tuning in particular is sorely missed in Comma (although they're working on it). And the larger model size puts it a little closer to being actually useful.

New open model: Apertus

Tech report here:

https://github.com/swiss-ai/apertus-tech-report/blob/main/Apertus_Tech_Report.pdf

They release 8B and 170B models, pre-trained and instruction tuned. Open weight and open data.

Data ethics are somewhere between OLMo […]

Recently there has been a lot of discourse about ActivityPub and AT Protocol which has been quite dividing and heated.

Yesterday at the Social Web CG meeting (the group that maintains the ActivityPub and related specifications), I proposed releasing a statement that counters the narrative that […]
