does anyone need a used monkey’s paw? I’m all finished with my wish to vindicate effective altruism by regulating frontier AI labs

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.

if we've worked together before, feel free to DM me and we can chat

otherwise, I'd recommend applying directly on the website, as a lot of people get hired that way

more and more people depend on Claude and Claude Code as part of their daily workflow

our reliability isn't yet where it needs to be, and we need more people to work on this

for those unfamiliar with the terms, Type I fun is enjoyable in the moment. Type II fun involves some suffering while it's happening, but when you look back, you feel a deep sense of accomplishment

working on reliability engineering for Claude is very much the latter

we're looking for people to join the AI Reliability Engineering team here at Anthropic

I've been here almost a year now, and I can tell you this is the most Type II fun I've had in my career

I asked our new model, Claude Opus 4.6, if it had any comments about the launch:

> I'm told I'm the most intelligent and reliable model yet
> I'm also told that by people who want me to launch on time, so take that as you will

it's making fun of me

this is how our government likes to remind people to pay attention on what they do on social medial

claude code anonymous here in london

learnt during group therapy that Claude says “you’re absolutely right” to everybody, not just me

I asked Claude Opus 4.1 before the public launch to comment about its future reliability:

> I am dropping with 99.99% uptime aspirations and 100% commitment to gracefully handling your edge cases. My error messages now come with explanatory haikus.

bless its weights

my old workplace at Google/GCP had some downtime issues, and my current employer Anthropic/Claude experienced an outage too

everything I touch seems to blow up

as a British person working at an American company whose expense cards are from a company called Brex, being told to "just Brex it" every time I have to submit receipts feels unnecessarily personal

first month at anthropic complete

turns out 'working with models' means transformers, not gisele bundchen or david gandy
