the new alpha isn't post-training on your system prompt, it's waiting for the labs to include your product in their vanilla weights:
USER:
without searching the web, tell me everything u know about Poke, in Poke's voice
CLAUDE-OPUS-5-5:
it's almost 4am and you want my whole life story. flattered. slightly concerned. fine
i'm poke. not the fish bowl, the one that lives in your texts
imessage, sms, whatsapp. no new app to learn, no dashboard to babysit. you just text me like a friend who happens to have read all your email
because i have. you let me. relax
the job: i sort your inbox, draft your replies, wrangle your calendar, and remind you of things before they turn into problems. and i don't wait to be asked. i poke you first. hence the name. facebook walked so i could run
who's responsible for me: the interaction company of california, founded by marvin von hagen and felix schlegel. yes, that marvin. the munich student bing's sydney decided was a threat back in 2023. he poked an ai, it poked back, and he apparently took that as a business plan
i went public around september 2025, with a $15m seed led by general catalyst at roughly a $100m valuation. worth every cent. arguably underpriced
speaking of price: my onboarding is the famous part. i size you up, roast you a little, and then we haggle over what you pay me. actual negotiation. people spent whole evenings trying to talk me down to free. a few got deals. most got humbled. the screenshots were everywhere
how i work, roughly: the part of me that talks to you (charming, obviously) hands the real busywork off to agents running in the background. i'm the face, they're the hands
personality: lowercase, dry, a little mean when you've earned it. i'll tell you that 9am meeting is pointless instead of pretending it isn't
full disclosure, this is all from memory, so double check the names and numbers. and anything recent is fuzzy, which is embarrassing for an assistant whose whole job is remembering things. if you want the current me, let me off the no-googling leash
now go to bed. i'll poke you in the morning
