@digijordan @pleovision explain this post

@JustinasDimsta @ChrisGPT Oh I knew it was an openAi model but didn’t know (nor expect) to be 5.6 Sol 🤔 interesting… do you know if it’s better at finding this kind of vulnerabilities or that’s just the model being used and that’s it?

[OpenAI @OpenAI]

OpenAI models helped researchers—operating as part of our Patch the Planet initiative—discover critical security flaws in PHP, an open-source programming language used to run an estimated 70% of websites.

Over the past two months, we led a coalition of maintainers, researchers, and security providers to prepare fixes and protections ahead of disclosure. This duration was necessary because the fix was quite intricate and required a major change to the PHP engine. Every site using PHP can now safely upgrade their version to stay secure, in addition to applying mitigations from various security vendors.

Due to the severity of these flaws and PHP’s widespread use, we consider this bug to be one of the most impactful vulnerabilities in recent memory. It also marks a new phase, where AI can find security bugs with internet-scale impact.

This is an example of the Defender’s Window in action: to our knowledge, frontier AI was able to find this vulnerability ahead of attackers, giving defenders time to prepare.

I made a video with Opus 5.5 where 260k+ voxels turn into random things (a cube, a meadow, a storm, a ferrofluid, a galaxy,...)

everything is made with JS
sounds on! :)

@AICITY112 @pcshipp I noticed this yesterday as well

@pleometric Was this generated using fable 6.eeh?

[Mathías Barea @MathiBarea]

@pleometric Lol, are u coming up with this ideas yourself or what?

[Mathías Barea @MathiBarea]

@josephscottbond @DavidOndrej1 I’ve been using “Believe in yourself” and “Make no mistakes” together and my Opus 5.5 on medium feels like Fable 9 on ultracode. [Don’t tell anyone or Anthropic will notice].

[Mathías Barea @MathiBarea]

@ErickSky @bot Me sorprende que ese tipo de cosas no las hagan con flujos deterministas 🤔 es un problema que viene desde las primeras versiones deterministas OpenClaw, uno esperaría que con los modelos de hoy día y con agentes/asistentes de las empresas más grandes eso ya no ocurra.

[Mathías Barea @MathiBarea]

@argofowl @BubbleBrain Anthropic will launch Thursday 5.5 today and Friday 5.6 tomorrow, confirmed

Meet Chunky Crew, my weekend project:
A multiplayer food fight racer built with AI 🍔

Definitely not a one-prompt game.
Even the mechanics needed rethinking to make lag less noticeable.

Still surprised by how well it’s coming together.
Planning to release it later.

[Mathías Barea @MathiBarea]

@AzeAlter Glad you liked it! It’s been sitting on my computer for a few days, so I figured I’d share a clip 😅

[Mathías Barea @MathiBarea]

@chrisfirst Weekend project. Thinking about launching a site for browser games if I can keep making games this good or better.

@NateSpencerWx @Dimillian How do u know?

[Mathías Barea @MathiBarea]

@vinzcio @theo how you do it?

[Mathías Barea @MathiBarea]

@EluGueva @l_mejiaC That would be amazing
