Image prompt: Top-down isometric pixel art scene in PS1 GTA style showing busy intersection with elaborate checkpoint barriers and glowing safety gates, chunky sprite vehicles flowing through organized lanes with neon warning signs and traffic control systems, saturated yellows and oranges for caution markers against dark asphalt, dithered textures and high contrast CRT glow, retro 32-bit aesthetic with visible chunky pixels.

This is interesting for a lot of reasons, including helping explain how model personality drift happens (and an easy way to mitigate that) as well as more exploration into the “Assistant” the key personality of basically every AI you work with, but which is not well understood.”” https://x.com/emollick/status/2013420897403543681
Anthropic keeps inventing new approaches to how agents work that then get adopted universally. First MCPs now Skills (which are an excellent tool). Also good to see fast adoption of good standards.”” https://x.com/emollick/status/2011890972121293235
AI agents have gotten good enough at long horizon tasks that it is an inflection point in the impact of AI at work. Agreement on this from METR, GDPval & now Anthropic. If you have a tool that saves 8 hours 65% of the time, that changes work, even counting potential error rates.”” https://x.com/emollick/status/2012237630411292859

Still commanding AI to make one weird game demo a day. This one: “”A game where you need to stop a spaceship from crashing into the sun and your only tool is future Claude Code.”” The entire design & all puzzles 100% AI, I gave minor UX feedback.

Not to repeat this, but the fact the Gemini chatbot can’t seem to deliver files (or even consistently run code) is a huge gap compared to ChatGPT or Claude. It makes a very smart model (Gemini 3) much less useful, especially for people trying to get AI to do real tasks and work.”” https://x.com/emollick/status/2013657294366478514

Opus 4.5: “”you need to build a game that is coherent, fun and story driven. There are precisely two controls. One is slider, in which one side is labelled Maximum Potato and the other is labelled Formalware, there are four positions for the slider. The other is a dial that goes”” https://x.com/emollick/status/2013466698121113981
When my students were creating initial demos with Claude Code & Antigravity, the AI would often spontaneously decide to do Wizard of Oz demos. The AI would build an interface, but not underlying logic. Code would (live!) run the interface behind the scenes to make it look working”” https://x.com/emollick/status/2012212148915654753

Claude’s Constitution \ Anthropic https://www.anthropic.com/constitution
Claude’s constitution is out! It’s the culmination of a lot of work by many people, but it’s also a work in progress that will no doubt change and hopefully improve over time. I’m looking forward to people’s thoughts, and to talking with more people about this kind of work ❤️”” https://x.com/AmandaAskell/status/2014010171081581048

If you ask Claude 4.5 for the name of a software developer, you are going to get Marcus Chen. Wizards are mostly named Aldric. Space pilots are Kira. (I’d been meaning to do this myself at some point, since this repetition is so obvious to Claude users) https://x.com/emollick/status/2013057279990407418
The Claude Constitution shows where Anthropic thinks this is all going. It is a massive document covering many philosophical issues. I think it is worth serious attention beyond the usual AI-adjacent commentators. Other labs should be similarly explicit. https://x.com/emollick/status/2014042317162791095
We’re publishing a new constitution for Claude. The constitution is a detailed description of our vision for Claude’s behavior and values. It’s written primarily for Claude, and used directly in our training process.”” https://x.com/AnthropicAI/status/2014005798691877083

Dear “”AI bubble will pop”” doomers, I hate to break it to you, but: – if the bubble pops tomorrow and OpenAI/Anthropic go bankrupt, their assets (including the frontier models and datacenter assets/rights) will just be acquired on the cheap by the big tech companies.
