Super exciting news 😎🎉 Building at the frontier of AI + Media @ Sima Labs with my co-founder Sophie Raniwala (in the pic below) has been electric and exciting ⚡️ I’m thrilled to share that we’re joining Meta 🥳!!! Super pumped to ship and build at massive scale (WOW —> 3.5B+ users is a lot across Instagram + WhatsApp + Facebook + the entire FoA (Family of Apps)). Building Sima Labs has been equal parts obsession, uncertainty, and pure joy. Some days felt impossible; others felt like pure magic 🪄 in the world of AI + media infrastructure. Along the way, our customers, investors, and especially our team showed up with a level of belief and trust we’re endlessly grateful for. Now we’re getting the opportunity to work on global-scale technology, with resources that finally match the ambition we’ve carried since Day 0️⃣ We can’t wait to keep building and to help accelerate AI + Media at Meta. PASSION | PATIENCE | PERSEVERANCE --> the motto along the way 🎶 CC: so many amazing friends + investors + customers along the way (many more, thank you!!) @hernanlopez @JonathanMoffie @whrobbins @etarczynski

@Etched big day :-) what is the "Etched Rack in Prod" birthday this summer going to be (July / August)? 🤩

We're coming out of stealth. We've built our first racks after a successful A0 tapeout, $1B+ in customer contracts, and $800m raised. Early customer tests show us achieving SOTA throughput, latency, and power efficiency on inference workloads. Our first racks ship this summer.

@meh_agarwal @adilmania @siliconmania my man have watched u perform 🤣🤣🤣

@Rushaanchess @adilmania @siliconmania bro you left before I performed

my man @adilmania putting on a performance @siliconmania 😎

@vladtenev @robertwachen @UbertiGavin cc @pitdesi who has all the best spots, this on your list

cc @vladtenev @robertwachen @UbertiGavin have you all been / thoughts?

INSPIRING Palo Alto spot! Diffusion Art & Creativity galore amazing work @mickymalka

@siliconmania keep crushing it : )

The Silicon Mania Mag April Edition drops this month. Last month, we launched our first edition and it ended up all over SF: OpenAI, xAI, Vercel, Notion, and a bunch of other cool places. We want to see where else it landed. If you have Edition 1, post a photo of it and tag us. We’ll send you Edition 2.

@alxmthew @berryaiplushies lots of joy for lots of people : )

Introducing Berry (@berryaiplushies): the first anti-sycophantic AI companion in a stuffed animal. I'm only 17 and we just went viral on TikTok, raised money from incredible people, and now we're shipping to thousands of teens by Christmas.

@nikhilaravi Amazing work, best part is on 1xH100 seeing this. Use-cases accelerating with SAM3 : )

SAM 3.1 is a drop-in upgrade to SAM 3 that 2x's video processing speed (16→32 FPS on a single H100) with no loss in accuracy. Previously SAM 3 tracked every object in video with a SAM 2-style masklet, so inference cost scales linearly with the number of objects. To support 30fps inference in practical applications we had to parallelize across multiple GPUs: up to 10 objects on 2 H200s, up to 28 objects on 4 H200s, and up to 64 objects on 8 H200s. There was also no shared object-level context, making it harder to resolve ambiguities in crowded multi-object scenes. SAM 3.1 addresses both these issues through object multiplexing. 16 objects are processed in a single forward pass on one H100 GPU. Shared global context across objects also gives a slight accuracy boost on crowded multi-object tracking scenarios. 👇Try it out and let us know what you use it for!

Meeting @bcherny at Meta SF office was fantastic. Qq @bcherny what part of your time at Meta has been most helpful at Claude Code? (apart from obv answer Dogfooding)

@facebook turned 22 today! Super grateful to see such a special founder in Zuck! It takes a fantastic leadership team with so many greats to build this generational company reaching billions of users. Grateful on the bet they took on us 😎 so much to build and learn : ) Meta shared the upcoming Super Bowl ad that the whole marketing team has completely crushed 🫡 meta.com/blog/oakley-me…

@hugothomel hmm interesting, what u are saying small model per game sounds like a cool idea. DM'd u, we should meet up

@Rushaanchess There's a fine line, enough data for generalization, not so much you overfit. Even wondering if the first big games will need to be one model. In an action game, you could have one tiny model per level. Easier to train, easier to run, swap them ontransitions. What do you think?

i built the 1st "world model game engine" it makes games from scratch, all running locally on my Mac M1 - 30fps - 40ms latency - ⁠50 million parameters - trained on 15 min of footage made using only "synthetic" datasets this is the first of its kind, & you can try it now

@maticrobots Congrats -- so cool to see what Matic can do : )

@JonathanMoffie @bokelley Love these deepdives @JonathanMoffie today I saw someone share a deepdive into how their app has been doing on mobile ads with Apple especially: docs.google.com/document/d/1bO…

Agentic does not just automate advertising. It expands it. Smarter budget allocation beats faster bidding. @bokelley explains why that shift could double TAM from $1T to $2T. CES felt like the opening bell of an Agentic arms race 🚀

How should founders spend time over the holidays? Besides rest & family, it’s a time to seek inspiration. Read books, visit a museum, hike, write, have a deep conversation over wine, synthesize thoughts. Many of my best ideas have unintentionally hatched Dec 20-Jan 6.

18-year-old founders of "The Pied Piper of GenAI" exit to Meta 🤯 Great journey to watch the team cook
