have people you admire and want to become more like?

match them on repetitions, it's a simple, beautiful trade of time

[Ben Fleming @benfleming__]

@KanishkaNarayan @NVIDIAEU @i_dot_ai @ElevenLabs @HP @nebiusai @SebJohnsonUK my man, great to see

[Ben Fleming @benfleming__]

product community & builders join the conversation!

we all win with more awesome, thoughtfully-built products in the world🌍

open source, with a charity contribution

[Propane @propane_ai]

We're building the biggest qualitative research project in product management history, open sourced and with $10 donated to charity for every interview.

The PM role is the biggest bottleneck in the agentic world and we need your voice, your take, your view of the future.

take your work seriously
take your pleasure seriously
take your health seriously
take your friendships seriously

@DanNeidle can verify living in denmark having lived majority of my life in the uk

denmark is much more expensive in many ways, but phone services are significantly cheaper

says a lot

[Ben Fleming @benfleming__]

caffeinate becoming my most used terminal command nowadays…

use it!

[Ben Fleming @benfleming__]

kinda wild that laptops don’t have built in cellular yet

[Ben Fleming @benfleming__]

@levelsio love how as I was reading this I was going to mention/reply that we should make a page of where is actually good value and where the market platos

then I get to the bottom of the list and there is already hotel list hahah

[Ben Fleming @benfleming__]

@SebJohnsonUK that fact it’s a question gives you the answer🤫🇬🇧

[Ben Fleming @benfleming__]

@levelsio no excuse even on a plane with no wifi especially now there are amazing local models with ollama

gemma 3 for example is amazing and runs on a macbook

@hjoelxyz louder for the people in the back🇩🇰

[Ben Fleming @benfleming__]

@serenaa_ge reallly cool!

where does composer 2.5 slot in here??

[Ben Fleming @benfleming__]

@hjoelxyz fire

[Nicholas Joseph @nickevanjoseph]

Excited to welcome Andrej to the Pretraining team! He'll be building a team focused on using Claude to accelerate pretraining research itself. I can’t think of anyone better suited to do it — looking forward to what we build together!

[Ben Fleming @benfleming__]

wow anthropic are.. reaaally gonna rip

[Andrej Karpathy @karpathy]

Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

[Ben Fleming @benfleming__]

@Jameswise no signs of stopping

bright horizons!

[Ben Fleming @benfleming__]

from scratch will be interesting

composer-type models show cursor have a good rl posttraining setup

keep moving down the stack… they’ll be making chips soon

[Cursor @cursor_ai]

Together with SpaceXAI, we’re training a significantly larger model from scratch, using 10x more total compute.

With Colossus 2’s million H100-equivalents and our combined data and training techniques, we expect this to be a major leap in model capability.

[Ben Fleming @benfleming__]

@itsFelipeDoria super interesting, shrewd example

is this an exception or does there seem to be a a rule on this?

[Ben Fleming @benfleming__]

@bullishLDN let’s goooo

seismic vibe shift in london over the last year, love to see it!

[Ben Fleming @benfleming__]

if london had as high trust as copenhagen

it would be unstoppable..

lean into trust, even if you get burnt occasionally, it’s still 100% worth it - just the cost of doing business

people are generally good and want to help!

let’s focus our energy on building instead🇬🇧

[Ben Fleming @benfleming__]

@threepointone irlmaxxing

important stuff

[Ben Fleming @benfleming__]

@hkanji seismic vibe shift in the last year also

horizon is bright
