have people you admire and want to become more like?
match them on repetitions, it's a simple, beautiful trade of time

The US just banned its best AI model, Fable 5. Kimi K2.7, a free Chinese one is already right behind it.
The open-weight model Kimi K2.7's just scored second on ErdosBench. Better than GPT-5.5 xhigh.
ErdosBench evaluates models on hand-crafted proof problems that aren't in any training data, so it's measuring real reasoning.
The single best model on the planet is locked away, while a free, open-weight Chinese one is sitting right behind it and ahead of everything else out of the US.
> LLMs are commoditizing
> Startups like Strawberry will soon be post-training and hosting our own open-weight model forks
> US keeps torching its trade relationships and undermining its AI companies
> China moves towards becoming the world's de facto economic superpower
I really hope Fable becomes globally accessible again, it's a great model and the world should be able to use it.
Blocking your own best model while open Chinese ones catch up makes no sense.
Kimi 2.7 ranked 2nd after Fable 5 and before GPT-5 xhigh
We have re-run our ErdosBench smoke test on 14 problems with Kimi 2.7, Qwen 3.7 Max, Grok 4.3 and compared it with the top performers from previous runs.
Kimi 2.7 is amazingly good. More below.

the best engineers in the ai era invert the trend in this graph
models encourage bloat, best engineers sculpt with precision

product community & builders join the conversation!
we all win with more awesome, thoughtfully-built products in the world🌍
open source, with a charity contribution
Jun 3
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.

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!

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.

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

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.

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🇬🇧

alignment is the new bottleneck in building great products — inspired by a great talk from @Mappletons (shoutout @aiDotEngineer @swyx)
@github are seeing it, we are too.
a static spec can't anchor a fast-moving product. it creates an alignment tax:
- building on stale context
- circling on settled decisions
- mornings in syncs instead of deep work
the fix isn't more process. it's a spec that updates when your product does — signals attached, context current.
open it and you're reading what's true now, not six weeks ago.
that's what frees up time for building exceptional products, what we're about at @propane_ai.

one ritual I'm glad to see the back of: the standup
15 min every morning describing work that could be read..
in @propane_ai , I can just ask. no breaking flows!
15 min/day back to human collaboration & problem solving - stuff that matters!
what can we build to save you time?

don’t forget to touch grass every once in a while..
and when you do, make sure it’s the luscious kind 🇬🇧

ship from live customer opinions🚢
talking to customers -> building cycle has never been shorter
all that's needed is great taste.. which fortunately we have in abundance in europe!🇪🇺
May 5
Product teams are already using Propane to run competitor research, ship features, and hand off specs directly to @cursor_ai and @Lovable.
Now you can push it directly Cursor Cloud Agent inside the canvas.

est 2012 - london is that ahead of the curve…
city of tastemakers, ain’t gonna change anytime soon
May 3
don’t tell me there is a pub called the tokenhouse in central london and we didn’t do an ai meetup in it yet

noticing in the ai era people trust more a commitment to taste, whatever that taste is
question: is it important to swag out a little more, express taste now?
examples:
- @alexandr_wang ferrari cap
- @WeAreLegora - lean into suits aesthetic
- @meetgranola - fun design

boom!
uk has some excellent plays around the corner
give it 5yrs it will be on fire
- fractile
- olix
- ineffable
- major ai companies all opening in kings cross
going for the whole stack - very bullish
* Anthropic is reportedly in talks to buy AI chips from Fractile, a UK SRAM-based AI chip startup whose product is expected to launch next year. -The Information
They’re buying something that hasn’t even launched yet?
