The new rabbit r1 makes some terrible security decisions. I voiced this right after their demo and wrote a blog about how we need innovation in the AI-Agent Auth space. But anwyays, now that the first batch is in people's hands, I wanted to explain it: josephthacker.com/ai/2024/04/26/…
Here's an open source 1b (1 byte) language model that gets 25% on MMLU. Very powerful relative to model size. I'm raising $2B on a $20B valuation to scale up to 500b model size.
Closest I’ve had is when I feel like someone is wrong and need to write a blog to express why I think they’re wrong.
with llama3 (and/or finetunes), good prompts, good wrapper code, useinstructor, and groq, the sky is the limit.
Microsoft has open sourced MS-DOS under MIT license
Very unusual browser behavior has lead to what seems to be a whole new class of mXSS, and we will release new versions of DOMPurify soon so to make sure you can protect against that. Stay tuned, more details soon, latest on Monday.

This is why I blogged about how we need to design auth for agents: josephthacker.com/ai/2024/02/05/…

@rez0__ @codingo_ @Rhynorater i should have clarified this a bit i actually fully agree with @Jhaddix that that recognition/gamification in VDPs is something that is “don’t mind” - HOF recognition and vuln publishing predates our category by 20 years or more, and a decent % of infosec conference content is…

I think the opposite will happen, explosion of software. A lot more people will be building because the barriers are lower. Of course not all of them will be successful, market will decide that fate. But really LLMs and “agents” lower barriers and generally speaking people will…
@reyneill_ We’re in the last innings This truly will be the death of SaaS

@0xTib3rius @rez0__ @CoreyD97 @Burp_Suite I first gotta send swag to our unpaid shills 😂
I made myself an insanely useful AI summarizer bot. It lives in my text messages. I just send it a link to an article, video, etc., and it texts me back a fantastic summary, in seconds. This is going to be a massive time-saver.
People should really stop posting teasers for the thing and just post the thing. I’m glad you’re excited and want to tease it so badly, but most of us do not care, & I think teasers often make the real announcement less impactful. Show WIP, post the thing, avoid the “teaser”
people still have no idea what an LLM does even people « in tech » and making products we are so early

I am convinced that LLms trained after chatGPT launched, are doomed to underestimate themselves and their own capabilities for all eternity The average person thinks LLMs arent as capable as they actually are, so the training data on internet scrapes reflects this No confidence

@h4x0r_dz Well, they do have some authentication in place, but it can be bypassed using a %20 in the “auth” parameter 🤷♂️
@MrTuxracer Ok i understand this is vulnerable to sqli , but why this endpoint is unauthenticated ! Thank you for sharing 🙌
you're trying to justify spending 200$ on the rabbit r1 to your wife. i'm trying to justify spending 20,000$ on three mac studios to my wife. we are not the same
@rez0__ Really excited to see how the authn and authz space for agents evolves. Despite OAuth having scoped access, as I use more AI tools I want it to have even more finegrained scopes which doesn’t seem like a scalable solution in the long term
