How differently do AI and the human brain really learn? 🤔

Mechanistically, very differently. But our new ICML paper reveals a surprising emergent alignment between the brain's Hebbian learning and regularized AI algorithms like SGD! 1/6

Many companies are #1 in a benchmark they crafted.

We worked with @micro1 to create an independently audited benchmark to measure document extraction performance with long documents.

The results of LongExtractBench show the nuances companies are likely to find in the real world. micro1 tested frontier models with max reasoning and document processing platforms with their strongest configurations, and found notable precision/recall and completion tradeoffs across most.

Reducto’s Deep Extract leads the industry by a wide margin. 🧵

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.

Big thanks to @LiuZiyin10 and Tomaso Poggio for their collaboration on this paper.

It also has an AI-powered deck builder. Check it out: https://t.co/dHfrtsffw4

I made a website where you can playtest Magic: The Gathering decks against an AI and other people.

We've uploaded a fruit fly. We took the @FlyWireNews connectome of the fruit fly brain, applied a simple neuron model (@Philip_Shiu Nature 2024) and used it to control a MuJoCo physics-simulated body, closing the loop from neural activation to action.

A few things I want to say about what this means and where we're going at @eonsys. 🧵

Announcing Flapping Airplanes!

We’ve raised $180M from GV, Sequoia, and Index to assemble a new guard in AI: one that imagines a world where models can think at human level without ingesting half the internet.

The future of marketing is psy-oping LLMs.

In a few years most big purchasing decisions will be guided by AI assistants.

This is scary — you have no idea what they’re saying about your product, and you have no way to change how they talk about you.

We built Unusual to solve this problem. We’ve already shifted model’s perceptions of top startups from being flimsy to enterprise-ready, and have seen AI-driven leads skyrocket accordingly.

Come work with us!

BREAKING: The shooting at Brown University occurred in the classroom of Prof. Rachel Friedberg—a Jewish professor in Judaic Studies.

We may have seen two mass shootings linked to antisemitism within 24 hours.

Happy 🦃 Thanksgiving weekend! 🍂 This year, we cooked up a new recipe for juicy fact-storing MLPs. Instead of picking apart trained models, we asked: Can we construct fact-storing MLPs from scratch? 🤔

Spoiler: we can & we figured out how to slot these hand-crafted MLPs into Transformer blocks as modular fact stores! 🧩

New work with @garctrob @ronnygjunkins @jerrywliu @dylan_zinsley @EyubogluSabri Atri Rudra @HazyResearch!

[Rox @rox_ai]

6 months, 25 million revenue agents & 3 trillion tokens later... Rox is now globally available 🌎

Just as coding agents 10x’d engineering, revenue agents 10x customer work.

With Rox, humans are evolving to orchestrators while agents manage the end-to-end customer lifecycle.

Even in Beta, Rox powered Global 2000 leaders in banking, hardware, construction, and sovereign AI, while serving dominant AI winners like @tryramp and @cognition.

Rox delivers ROI in 90 days and is built with the best.

Thank you to @OpenAI, @nvidia, @perplexity_ai, @awscloud, @vercel, @Snowflake, and @stripe for helping us scale.
