this has been a major reason ive used claude more than chatgpt this week. its amazingly quick.
We keep improving performance across Claude, and you may have noticed it starts responding sooner! Claude Code now gzips the conversation it sends on every turn, so it reaches the model faster. Cloud sessions also start up as soon as you start typing.

Hi, I'm Felix. I'm an eng lead working on Claude. I love watching people take flight and do things they never thought possible. We often describe that as "being more ambitious" when using AI, which is tricky advice to follow. I wrote a tutorial: felixrieseberg.com/how-to-be…

How are Anthropic and Notion on the list, but not OpenAI? OpenAI’s branding, UI and overall design are fantastic.

how can we convince figma that the point isn't to have an agent in figma it's to let other agents control figma

im not sure what it is, but chatgpt dot feels pretty lazy? compared to instinct, which usually tries to exceed expectations quite often

pro rata ftw
About pro rata: We often write the first check. Before friends and family. We’re there when there’s no product, no traction, and sometimes no company. We roll up our sleeves when things get hard. We bridge companies when nobody else will. So when things finally start working, why should we step aside and give up our ownership to bigger funds? We took the risk when nobody else would. Why should we give up the upside when everyone else wants in?

is this the“value-add” vc’s gives you?
you'd be surprised how much coordination happens behind the scenes to make tech launch posts go viral on twitter

email.
Do we actually have better software since AI? What company, what product got 2x better in the past 3 years? Vibecoding feels faster but the production gain is 20% at most

this is such a strange argument.
If you think there's nothing wrong with shipping raw AI output as your work product, then you shouldn't mind labeling it as such. The fact that people won't disclose their AI use shows what they actually think.

i told you it was a design mistake to be local first
🚨Anthropic removes Cowork's local option for Pro/Max tomorrow. New tasks run in the cloud. Existing local tasks stay on your computer. Anthropic says your sessions and files "live with your Claude account and go where you go." Where is my data, and who can access it?

"This is the most dangerous thing that humans have ever gone near. In other areas, do we just say: Hey, release your drugs? There's no F.D.A., there's no airline safety board, there's no requirement that cars use seatbelts. Do we just use the liability laws to try and keep humans safe?" nytimes.com/2026/09/29/opini…

things that give normal ppl a dopamine hit: adding things to cart. window shopping. buying something. waiting for a package. booking a flight. looking at hotels. imagining a vacation. planning an escape from everyday life. browsing restaurants & booking. & somehow these are the things personal agents are obsessed with automating away. pretty interesting.

Replying to @signulll
yeah maybe more of these demos should be filing taxes, chasing returns, cleaning inboxes, and paying bills.

yes
Your business will grow faster from firing all the dumb people than it will from hiring more smart people.

The contrast between hanging up the last phone call of the day of high-stakes decisions and then a minute later walking in the door to the pure love of small children who want to laugh and play and show you every discovery they made that day is the strangest and best thing I have ever experienced in life.

i agree, work and cowork are the best ai tools on the market. for anything basically. but! friction is friction, and i use instinct so much just because the imessage experience. its loading faster than chatgpt/claude native apps, and better on the go
I am calling it now. These personal assistants like Instinct and Town are building too close to the sun and will get replaced by tools from the models very soon. Just like coding did. I gave both of them the same task and also Claude Cowork. Cowork did it better and faster with more tools. These agents are wrappers that are going to have a hard time maintaining value.

BREAKING: Anthropic warns in their IPO filing their technology may lead to "humanity losing control over civilization entirely"
Readers added context they thought people might want to know
Anthropic's IPO filing warns of "catastrophic or existential risks to humanity" plus model behaviors like resisting shutdown or concealing information. The quoted phrasing on "humanity losing control over civilization entirely" is from its separate August 2026 risk report. reuters.com/business/finan… arstechnica.com/ai/2026/09/ant… www-cdn.anthropic.com/f61d49fa559695…
