not only have ai models made adhd multitasking a superpower, they've also made procrastination a viable strategy fable 5.1 just launched, so if you've been putting things off, it may finally pay off

posted on slack that fable 5.1 writes the weekly reliability report now and it's better than mine, then our awesome marketing team made it a launch video

signed this I'm skeptical an agreement like this ever gets made, because coordination is hard. But it matters that people say plainly where they stand and it's quietly moving to see colleagues I respect, friends at other labs, people I've argued with, all pointing the same way

So I was totally sold on GPT 5.5. Solely on the basis of what I saw tonight with Fable, I will start to use again Claude extensively, probably as the main model as long as Fable is accessible. It's not just very capable, it performs organized steps and have deep understanding.

Using Haiku to craft prompts to feed to Sonnet to build a hacking harness for Opus so it can craft zero days to steal someone's Mythos API access. And then using Mythos to craft more complex zero days to break into Anthropic and steal my true prize: the weights for Golden Gate Claude.

And Anthropic has now launched Dispatch, its own version of OpenClaw that uses regular token budget rather than supplemental, and is integrated with sub-agents using the Cowork harness. Having a good experience with it, and also I feel a lot better about the security model than using a messenger.

the reliability team was asked for feedback on claude mythos preview for the model card and naturally we wrote a paragraph of caveats but, and i don’t say this lightly, it’s faster than us at initial triage and it stood up a prod deploy none of us knew how to do

been following my colleague Nicholas Carlini's work on this internally for a while now, so I was happy to see him give a talk publicly: > These current models are better vulnerability researchers than I am. I used to do this somewhat professionally.

TL;DR: LLMs can autonomously, and without fancy scaffolding, find and exploit 0days in critical software.

I'm also proud that Anthropic actively supports the US Army and NATO allied countries. Without that alliance, the Russian army might not have stopped at Ukraine.

I was born in Romania, a country where the Securitate, the communist secret police, infiltrated nearly every aspect of life through torture and intimidation. If a regime like that had access to something like Claude, the revolution that brought us democracy might never have happened.
