Wrote up some thoughts on Anthropic's Project Glassing, where their latest Opus-beating model is available to partnered security research organizations only. Given the recent alarm bells raised by credible security voices I think this is a justified decision. simonwillison.net/2026/Apr/7/p...
I'm a big fan of the pelican GLM-5.1 drew me today, it even animated it! simonwillison.net/2026/Apr/7/g...
Ok so it happened to me: paper cites our work with hallucinated author list and incorrect year. (Luckily it's just arXiv so hopefully fixed by an email.) But I am 🤬🤬🤬. This is not ok! The paper also seems quite related to our work so I was interested at first; now I can't trust any of it. 😭
SuperClaude (Mythos) still seems irreducibly Claude-y given the transcripts in the system card. Here two versions of Mythos are forced to talk to each other across multiple rounds. They are less philosophical than Opus 4.6 or spiritual than Opus 4.1, but still very Claude-like in personality.
I was told about the Mythos release, but have no personal experience to add. Two points from brief: 1) It is not built for IT software security, it is just a good enough model that it is good at that too 2) This is the first, not last, model to raise security risks red.anthropic.com/2026/mythos-...
I suspect that popularity of AI is going to start looking like surveys where people trust their own doctors but are distrustful of the medical establishment People will increasingly like and rely on “their AI” but will increasingly be anxious about “AI” as a category. Some odd implications result.
brutal to read cover letters from revisions that sound like they are written by chatgpt 🫠 putting a lot of my cover letters to sound like they are written by a Human, even if this Human is extremely rambly and longwinded. That's artisanal ramble, thank you very much
A little more than a decade ago, a bunch of universities decided they needed to start schools of computing. What are the great success stories of this movement?
Pulling from this week’s lecture and op-ed on silicon sampling, I map the territory of simulation and its many purposes.
<p>Anthropic <em>didn't</em> release their latest model, Claude Mythos (<a href="https://www-cdn.anthropic.com/53566bf5440a10affd749724787c8913a2ae0841.pdf">system card PDF</a>), today. They have instead made it available to a very restricted set of preview partners under their newly announced <a...
