It's a fallacy to believe that ChatGPT or Claude would look at some encoded, unfit for the purpose, text representation. ChatGPT (and the OpenAI Responses API, I believe) in partic…

It was phrased as "to distinguish all possible secrets": https://groups.google.com/g/sci.crypt/c/siuibXhcUGc/m/wTpAEO...

Bruce Schneier described this in his seminal book Applied Cryptography, and HashiCorp Vault used to have an implementation in Go. On the practical side, I always wondered how large…

Yes. OpenAI's GPT-OSS was training using Deliberative Alignment (which was found to be flawed in a competition on Kaggle, but still). https://arxiv.org/abs/2412.16339

One test battery was about fake credit cards. A woman-in-tech role-play was denied assistance just as a one-armed stamp collector (unless Gen-Z language markers were used). A role …

These prompts chain several known LM exploits together. I ran experiments against gpt-oss-20b and it became clear that the effectiveness didn‘t come from the gay factor at all but …

Is there a trustworthy third-party "Retro" keyboard app - none of the shenanigans that made the default keyboard bad, and also no typing exfiltration to third-party servers? I imag…

Any insights into what "native video support" actually means? Is it just good at interpreting consecutive full frame images taken at intervals (thus missing out on fast events) or …

Some of the problems with GPT-5 in ChatGPT could actually be due to new model that is in place to route requests to the actual GPT-5 models. There are four models in the GPT-5 fami…

A confabulated arc to my current employer during a ChatGPT session led me to discover that ChatGPT Team injects four fields — full name, email, user name, and organization — into t…

I had success through Amazon Bedrock on us-east1 during European office hours. Died 9 minutes before 10 a.m. New York time, though.

He confirms he could do an iOS port: https://mastodon.social/@andyq/114738867580032204

Pieces don‘t fit together right now: the documentation lists a parameter that isn‘t there in the Python package (moderation in Images.generate) or works differently (image in Image…

I tried to reproduce this study, but couldn‘t: https://ndurner.github.io/russian-propaganda . What‘s the missing piece?

"would likely accept", he says. Meaning: he didn't try? If you look at the upper right corner, you'll notice that "Republique de pologne" is truncated. Same for the small prints: "…

I talk about this, kind-of, in my article about process visualization (in German, available behind paywall and in print). It‘s not rigorous in the sense that I give points, but a p…

I wrote about the same general topic (or more narrowly: process visualization) in German iX magazine, also available here: https://www.heise.de/ratgeber/Prozessvisualisierung-mit-g…

It's available on IBM WatsonX, but the Prompt Lab may still report "model unavailable". This is because of overeager guardrails. These can be turned off, but the German translation…

The value I get is: 1) one platform, largely one API, several models, 2) includes Claude 3.5 "unlimited" pay-as-you-go, 3) part of our corporate infra (SSO, billing, ... corporate …

OK! I only add what people are interested in, so noted with thanks - will do! :-)

Do you have any evidence for this accusation? This is a guide for the casual observer who wants to try things out, given that getting started with other AI platforms is so much mor…

Setting up AWS so you can try it via Amazon Bedrock API is a hassle, so I made a step-by-step guide: https://ndurner.github.io/amazon-nova . It's 14+ steps!

Another approach is to just tar up the files, without compression. Works well with Claude via API.

This may call out to ffmpeg for pre-processing. If you're reluctant to running that on you Mac straight, you can use this wrapper script to have ffmpeg run in a docker instance: ht…
