It's time to announce a large-scale project I have been working on for the past 2 years with a team of security researchers @einstais @calderpwn @edeirme and @beauwoods - a book on "Practical IoT Hacking" to be released this September by @nostarch Press: amazon.com/Practical-IoT-…

here is o1, a series of our most capable and aligned models yet: openai.com/index/learning… o1 is still flawed, still limited, and it still seems more impressive on first use than it does after you spend more time with it.

.@BSidesSF 2024 talks are up! just watched a great one on using llms to scale security teams by @ithilgore and @PaulM check it out! youtu.be/WQIFDnu-c6g?fe… the eval part was interesting, and i’ll probably use the same approach to eval my galah dataset.

the dataset is available at github.com/0x4D31/galah/t…. evaluation needs some manual work, but will be up soon. check out how gpt, claude, and gemini respond to the cve-2024-4577 exploit attempt. exactly what i expected from @OpenAI🧠, @AnthropicAI🚫, and @GoogleAI🤪! xD

we think there is room to make search much better than it is today. we are launching a new prototype called SearchGPT: openai.com/index/searchgp… we will learn from the prototype, make it better, and then integrate the tech into ChatGPT to make it real-time and maximally helpful.


Fotis Chantzis Reposted

GPT-4o is now available in the API. It’s as smart as GPT-4 Turbo, has improved vision capabilities, and is much more efficient—2x faster, 50% cheaper, 5x rate limits. It supports text and vision today, with audio and video coming soon. Details in thread 🧵 openai.com/index/hello-gp…

We’ll be streaming live on openai.com at 10AM PT Monday, May 13 to demo some ChatGPT and GPT-4 updates.

Love the energy of the OpenAI team the day before a launch.

not gpt-5, not a search engine, but we’ve been hard at work on some new stuff we think people will love! feels like magic to me. monday 10am PT.

we are introducing the Model Spec, which specifies how our models should behave. we will listen, debate, and adapt this over time, but i think it will be very useful to be clear when something is a bug vs. a decision. openai.com/index/introduc…


Fotis Chantzis Reposted

using technology to create abundance--intelligence, energy, longevity, whatever--will not solve all problems and will not magically make everyone happy. but it is an unequivocally great thing to do, and expands our option space. to me, it feels like a moral imperative.

Great talk by @PaulM and @ithilgore at BlackHat Asia. There's an accompanying open source release of some of our bots/workflows at github.com/openai/openai-…. Very excited for us to continue working on this! PS: we're hiring if you want to come work with us!

Thank you all for attending our BlackHat talk with @PaulM on automating security workflows using LLMs! @BlackHatEvents blackhat.com/asia-24/briefi… #BlackHat #BHASIA We had tons of questions from the audience at the Q&A section, which was a great sign!

Dinner with homies from @OpenAI and @bugcrowd , then their talk this morning on how they use LLMs internally for security was definitely the highlight of the trip. Supremely validating on the type of stuff I’ve been building. Fantastic morning.

also, while I have your attention, I am hiring experienced product security engineers and software engineers. we're solving some cool security problems, and have a unique approach to solving it.
