@GergelyOrosz Threads works more like facebook, content surfaced to the relevant people in smaller groups.

X is 1 to many platform at its core and a few people have giant reach while others are stuck shouting into the void.

This is the holy grail in Consumer AI.

The world is much larger than Silicon Valley coders.

why do they always do livestreams for the garbage no one cares about but not for new models

Meta’s ethos is Connection.

And it is especially *costly*. When you bring together all of humanity, it’s best and worst impulses are apparent to see.

But the company and the people who believe in it, such as myself, we see that there’s more good in doing so. I have felt it. I have family in 4 countries, split by 15 time zones. Some days they feel like they’re in the room next to me thanks to the products this company has built.

[signüll @signulll]

regardless of how you personally *feel* about it every historically great company needs a moral ethos to use as an anchor to tell a great story to both their employees & customers. this is not a mission statement, certainly not values, & def not brand positioning. it must be a much larger cause for the greater good of society.

one simple idea that anchors the story. the most important part is that this ethos has to be *costly*. if it does not force you to say no to things that would otherwise make money, it is just marketing.

e.g. apple does this with privacy, anthropic does this with safety. usually this moral ethos is one word that ends in a y.

if companies lack this, then their story is usually all over the place & they are unable to say no to things. consider meta.. what is meta’s moral ethos? they clearly don’t have one which is why zuck basically attempts everything & the kitchen sink (vr, ai, etc).

since openai has had a bunch of fb ppl they sorta landed in a similar position. “benefiting humanity” is noble, but it is so broad that it can rationalize almost any product surface unless it becomes costly in practice.. when google had one (don’t be evil, im sure there is a y word here that fits neatly) they had this collective mechanic to rally both troops & users. since they abandoned it, the collective became somewhat hollow as you saw in the late 2010’s.

this is not really a moral judgment at all btw. plenty of large companies can exist without a strong ethos. they can make money. they can ship products. & they can even dominate markets.

but their cultural influence starts to wane. employees feel the hollowness first. then users. eventually the company can no longer tell a coherent story about why it exists beyond growth itself.

if you as a company find what this ethos is, & why it is costly to everyone then cultural relevance is yours for a long long time.

@signulll Meta’s ethos is Connection.

It’s the thread that connects everything, Facebook, Instagram, WhatsApp, VR, and especially AR.

guy selling post trained oss models: if you don’t own your models you don’t own anything

guy selling harness on top of models: if you rely on one model you are cooked

guy selling tokens: instead of manually prompting your models just put them in a loop where they prompt themselves

It’s crazy how much tech news ends up misunderstanding or accidentally distorting truth. It’s truly a game of telephone.

I see things said internally with context sound completely different outside.

[Alexandr Wang @alexandr_wang]

First, Mark was clearly talking about the industry’s progress on agentic capabilities on the whole.

But, while we’re on the topic: Our next Muse Spark update is coming soon. Big improvements in coding and agentic capabilities to be more competitive with other leading models.

Excited to get these into your hands—will be rolling out to Meta AI and our new API!

PPO had a second wave in the LLM era for reasons unanticipated by the original paper
- the importance-ratio objective fixes biases from numeric error, async training, and forward pass noise
- the clipping objective affects entropy through a mechanism that we didn't know about at the time of publication (DAPO, https://t.co/sBo9DeFS5Y)

I have a degree in Mech Engineering and I work as a Research Engineer on LLMs now.. what tier is this.

[Hubert Thieblot @hthieblot]

degree Tier List for today’s world:

S Tier: MechE, Physics, Math
A Tier: ML, EE, Aerospace, materials science

(Massive gap)

C Tier: pure CS

what if everything goes right

[Hurley @Johnsjawn]

Or go to the Presidio, jump in the ocean, get a coffee at The Mill, watch sunset at Twin Peaks, ride a bike anywhere, see live music, eat a burrito, take a grass nap in GG Park, have beer at The Page, watch the Bay Bridge lights, wander Chinatown, wander Ferry building, run across GG Bridge, walk Fort Funston, eat the best meal of your life with friends…drive any direction for 2hrs. And be deeply grateful for the heavenscape you live in.
