WHY ARE YOU LIKE THIS

@scottjla on Twitter in reply to my pelican riding a bicycle benchmark: I feel like we need to stack these tests now I checked to confirm that the model (ChatGPT Images 2.0) added the "WHY ARE YOU LIKE THIS" sign of its own accord and it did - the prompt Scott used was: Create an image of a horse riding an astronaut, where the astronaut is riding a pelican that is riding a bicycle. It looks very chaotic but they all just manage to balance on top of each other Tags: text-to-image,…

GPT-5.5 prompting guide

GPT-5.5 prompting guide Now that GPT-5.5 is available in the API, OpenAI have released a wealth of useful tips on how best to prompt the new model. Here's a neat trick they recommend for applications that might spend considerable time thinking before returning a user-visible response: Before any tool calls for a multi-step task, send a short user-visible update that acknowledges the request and states the first step. Keep it to one or two sentences. I've already noticed their Codex app doing…

The people do not yearn for automation

The people do not yearn for automation This written and video essay by Nilay Patel explores why AI is unpopular with the general public even as usage numbers for ChatGPT continue to skyrocket. It’s a superb piece of commentary, and something I expect I’ll be thinking about for a long time to come.

Introducing Reachability for PHP

Introducing Reachability for PHP

Security teams are already struggling to keep pace with the volume of vulnerability disclosures. Every week brings more CVEs, and the arrival of AI-assisted vulnerability research is only going to push that number higher. Teams that can't tell which disclosures actually matter for their application will fall behind quickly. PHP carries more of this weight than most ecosystems. Composer ranks third for CVE volume among package ecosystems, behind only Maven and npm, and PHP still runs a…
