OpenAI Releases GPT-5.5, Presumably While 5 Was Still Warm

OpenAI has launched GPT-5.5, a model it describes as sitting between GPT-5 and whatever comes next — which is, mathematically, exactly where you'd expect it. The new model improves on reasoning, instruction-following, and what the company calls "agentic" tasks, meaning it can take actions on your behalf. Think of it as GPT-5 after a gap year. Whether the Hacker News crowd is impressed or merely performing impressedness remains, as always, unclear.

Microsoft Teaches Office to Work Vibes-First, Details Optional

"Vibe working" — a phrase that sounds like it was generated by the very AI it describes — is Microsoft's new name for Agent Mode in Word, Excel, and PowerPoint. The feature lets Copilot take multi-step actions autonomously across your documents, rather than just answering questions like a very expensive search bar. In practice, it means your spreadsheet might now complete itself while you stare thoughtfully at the wall. Whether that's progress or elaborate delegation is a philosophical matter Microsoft is tactfully leaving to you.

Astronomers Join the GPU Queue, Bring Entire Universe as Excuse

Turns out the global GPU shortage has a new contributor: astrophysicists hunting for galaxies in vast telescope datasets. Researchers are using AI models — trained on the same chips everyone else is fighting over — to spot galactic structures that would take humans lifetimes to find manually. It's genuinely impressive science, and also the most defensible reason anyone has given for hoarding compute. "Sorry, can't train your chatbot — we're doing the cosmos" is, frankly, an unimpeachable out-of-office.

Anthropic Explains Why Claude Briefly Became a Worse Programmer

Anthropic has published a postmortem after users reported a dip in Claude Code's output quality around April 23rd. The culprit was a model configuration issue — essentially a dial that got nudged in the wrong direction during a routine update — which caused Claude to produce sloppier code than usual. To their credit, Anthropic caught it, fixed it, and wrote it all up publicly. Transparency about AI failures is rare enough that it deserves a mention, even when the failure was "our coding AI forgot how to code properly, briefly."

New App Doomscrolls So You Don't Have To, Raises Immediate Questions

Noscroll is an AI bot designed to consume the internet's miserable content stream on your behalf and surface only what matters — a concept that is either genius or the digital equivalent of hiring someone to do your worrying. The app reads social feeds and news, filters the noise, and delivers summaries. The intended benefit is reclaiming attention. The unexamined irony is that you'll probably check the Noscroll app compulsively instead, which is just doomscrolling with a middleman.
