So Mythos was, indeed, not marketing hype. Remember this is a general purpose model that just happens to be good at finding exploits because good models are good at lots of things. Expect similar from OpenAI & Google. And from open models in 8 months.

The UK’s state AI Security iIstitute findings: 1) Mythos is a big gain in cyber capabilities. But so is GPT-5.5 2) It is hard to establish an upper bound on Mythos/GPT-5.5, which appear to be limited by tokens used, rather than ability. 3) Capability doubling time is 4.5 months

Daybreak: Frontier AI for cyber defenders

OpenAI is launching Daybreak, our effort to accelerate cyber defense and continuously secure software. AI is already good and about to get super good at cybersecurity; we’d like to start working with as many companies as possible now to help them continuously secure themselves.

Agent observability is a means to an end: making your agent better. But observability and evals tools have traditionally failed to connect traces to meaningful actions. Agent engineering teams are left combing through traces, guessing at root causes, and writing evals manually.

Alignment research often has to focus on averting concerning behaviors, but I think the positive vision for this kind of training is one where we can give models and honest and positive vision for what AI models can be and why. I’m excited about the future of this work.

Human values are a kind of misgeneralization. If humans learn our motivations through neural reinforcement, pleasure and pain, in theory we might expect all humans to care about nothing else. But we do. We learn other values, because they are pretty good proxies for reward, and

I suspect there was a moment, probably 2022-2023, where anything you wrote publicly about AI that was popular is likely to still have influence over current models. Since then, the open internet has become less key to training but the models remain very 2022-brained in many ways

I think frontier model writing is good! It often has a sense of style & tone, variations in sentence structure & length, some great phrasing, etc But it also has some weak spots (fiction!) & clear tics. Mostly there is just far too much of it online which makes it all so cliche

Most model trainings have failed outside of frontier labs. Even inside frontier labs, knowing how to train for very different capabilities is often a matter of taste. Today, we introduce AutoScientist by @adaption_ai which sets out to change that.

Stop turning prompting into magic spells (and yes, this includes random slash commands with obscure outcomes). Let this one area of working with AI not be weird. Just ask for stuff, in well-specified formats, like a manager, not a sorcerer with a bunch of incantations.

The inability of AI systems to act as their own deployment consultants, process mappers, and change management experts is what makes AI use in enterprises so “normal” – the tools are powerful, but you need a lot more to transform enterprises. Possible to imagine that changing .

This is going to get even worse as people realize that careful tuning in their prompts can make AI writing seem not like AI writing to readers. We expect word counts to align, in some way, with thinking & value. Writing took effort. We are not mentally ready for the alternative.

I realize that “Mythos as hype” means two different things to different groups. For insiders, it means “Mythos was not a magical step-change in AI ability.” For outsiders, it means “Mythos couldn’t really find zero day exploits” The latter was wrong, the former was likely right
