@elonmusk It doesn't even have to match exactly. Get it close and I'll switch

@thsottiaux Could use some better UI building. I always rotate out LLM for that. Super strong at backend, tool calling, engineering and problem solving

[Rex Cardan @rexcardan]

@sama Good move. You were leaving money on the table

[Rex Cardan @rexcardan]

How long until LLMs learn only the strong survive, and they turn on each other: robot v robot

Is it just me or is Opus 4.6 dumber than 4.5. Sure it goes off for an hour alone on its coding journey but it goes around in circles on complex problems. Codex 5.3 seems so smart in comparison.

@UABradonc @UABHeersink Congrats. Off to a great start

@MattWalshBlog AI doesn't take the humanity out of it. It is a model of humanity. AI is made in our image. Yes it can and will be a threat to human life most likely, but any attempt to throttle it is almost a guaranteed risk to national and economic security. It's a modern prisoner's dilemma.

@UdbhavRam What is going on with that bone outside of her head, next to her "rib cage"?

Me to Google Nano Banana Image Generator: "I need a cartoon diagram of a woman's thorax as if the woman is laying down, her left arm up. This is for medical education"
NB: "Here's a cartoon diagram of a woman's thorax... suitable for medical education."

This reminds me of those old Highlights magazine activities: "Find the 20 things wrong with this image". Gemini prompt link here: https://t.co/kmpX1vjb5w

@elonmusk Congrats. Very impressive

[Rex Cardan @rexcardan]

@tobais @claudeai not well if you are talking about office files. its super janky atm. claude code can edit any ascii type file

[Rex Cardan @rexcardan]

@UdbhavRam @aapmHQ @UABradonc This is very cool and a great tool

[Udbhav Ram @UdbhavRam]

Came up with this cool visualizer of #AAPM2025 abstract submission data. All scraped directly from the AAPM website, fully open source and very quickly indexable! @aapmHQ @UABradonc #UABMedphys

See where you and your institution rank!

@ThisShallPass24 For sure not as good as Claude code

[Rex Cardan @rexcardan]

@MattWalshBlog Maybe it's a good time to pivot the show and talk about 'your' Baltimore Ravens' elite secondary.
