@ankurnagpal If you are borrowing a few mil on an SBLOC, you can get something like SOFR plus 1.25%, which is currently around 5% and declining. A good strategy if you already have money parked in index funds— might as well use them as collateral!

@nearcyan just crazy enough to work

You . com offers to buy perplexity. Money is totally in the bank and ready to go. Also, Google, we offer to buy them also. TikTok? Certainly, for good measure.

[Shawn Shen @shawnshenjx]

I’m Shawn, founder of https://t.co/DLaNyXWuUn, former researcher at Meta and CS PhD at University of Cambridge.

Today we’re launching https://t.co/DLaNyXWuUn: we built the world’s first Large Visual Memory Model - to give AI human-like visual memories.

Why visual memory?

AI to date is chat-based, which has great applications, but humans are not only chat based. Humans have visual-memories, and are visually driven. https://t.co/DLaNyXWuUn enables AI agents, softwares, and even robots to see and remember the world the way humans do.

We just raised an $8m seed round led by @susaventures to build the visual-memory layer for AI.

Why is https://t.co/DLaNyXWuUn so groundbreaking? 👇

What an exciting week for our friends at @playai! A massive congratulations on their acquisition by @Meta. This is truly a landmark moment for them and a huge validation for the innovative technologies they've embraced.

We're thrilled to share that Vectara is the RAG-as-a-Service behind PlayAI's exceptional text-to-speech capabilities. Their incredible success with this acquisition underscores the critical role that Retrieval Augmented Generation (RAG) and Generative AI play in building impactful, scalable AI products. PlayAI's journey from a pioneering AI company to being acquired by a tech giant like Meta showcases the undeniable power and real-world applicability of a well-implemented RAG strategy.

This is more than just an acquisition; it's a clear signal that #RAG and #GenAI are at the forefront of the next wave of technological innovation. Thinking about how RAG could elevate your next GenAI project? We’d love to be part of your successful journey: https://t.co/yiSdf8pn5j

I said “walk and chew gum at the same time” in a meeting today, and the youngsters on the team thought it was hilarious—first time they’d heard that colorful idiom.

@jeremyphoward @l2k @wandb RF has stood the test of time, Breiman’s paper was in 2001!

@_rockt @NetHack_LE I wonder if part of the future solution will involve feeding the source code to a long context model
