@mitsuhiko You're not alone! I can't sleep if I don't fully understand the Rust code lol

On July 25, we hacked OpenAI.

Two bugs let us take over ChatGPT/Codex accounts of OpenAI employees (+some unaffiliated users) and reach connected services: Outlook, Slack, GitHub, etc.

We proved it with a PR in OpenAI’s internal codebase . It took us <72h. 🧵

@elonmusk @aaronburnett Cool! I'm just curious:
1. How much of Grok Build will be involved in this rewrite?
2. Does the team plan to open-source the new stack?

I resigned from Anthropic today. I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives. More thoughts below.

i’ve shifted from telling agents what to do, to asking them what to do, and pulling the best thread.

Fable 5 vs Grok 4.5 vs GPT 5.5

We put three top-tier models to build a same game challenge.

Used Command Code /design, and the exact same prompt.

Result:
Grok 4.5 genuinely plays like a polished mobile game.
Fable 5 and GPT 5.5 feel too fast. Everything feels rushed, lacks finish.

Ranking based on DX & Features:
→ Grok 4.5: 9/10
→ Fable 5: 7.5/10
→ GPT 5.5: 7/10

@goon_nguyen I said what I needed to say.
I don't hate you personally. I just hate scammers in VN.
That's all, I'm done.

[Khai Le @khai0x]

@goon_nguyen @RhysSullivan Of course, you guys didn't have a chance to scam me. For example, this one https://t.co/t9FXYTWbLd is a scam. What type of SOC 2 is it? Where is the evidence?

@mitchellh @jedisct1 Have you considered joining GitHub this time to make it even better?! 😜

[Khai Le @khai0x]

@aadityansha_06 @VazeKshitij It depends! Even on x86_64, if your program uses a 32-bit data type like “int”, the compiler will use %eax instead of %rax.
