I believe the top question in most tech investors' minds is - "where are we in AI?" I wrote a piece from the perspective of someone who spends a lot of time thinking about the public markets AND speaking with private companies https://t.co/aOZ0vUMnq5

Basically this - can do the math from a fully loaded cost perspective (15Bn+ of fixed costs in a DC) or from revenue perspective (like this) I think #1 being wrong is even more bullish for $NVDA bc NVDA can be used for all accelerated workloads vs ASICs / other GPUs which don't
The $NVDA long pitch is this: You have a finite space for a rack - this is limited by the walls of a DC, but mostly by how much power is available. On that footprint, you can place your own chips, NVDA, potentially ASICs, but the end goal is to serve tokens that you can sell +

Some analysis on "50m H100 equiv" target of Elon & xAI Assuming power / perf improvements: 50m H100s = 250x today's compute But reflects ~4M total GPUs and energy footprint of 11GW ! My best guess is Feynman will cost ~7x Hopper, but offer 25x perf (3-4x TCO passed along)
The @xAI goal is 50 million in units of H100 equivalent-AI compute (but much better power-efficiency) online within 5 years

Tons of great nuggets in this post from co-founder of Segment who just left OAI Since a lot of my audience is semis / AI investors - one in particular: "How to do GPU-math. We had to forecast out the load capacity requirements as part of the Codex launch, and doing this was the

GB300 bring up at CoreWeave. GB200 and GB300 going to hit AI infra like a wave. Once the majority of AI infra install base shifts to rack scale 72 GPU domain, so will the models and capabilities. Models and SW = water, will just pour more as the vessel (hardware) expands
We’re the first cloud provider to bring up the @NVIDIA GB300 NVL72, delivering up to 50x inference throughput and 10x user responsiveness for next-gen AI. Built in collaboration with @Dell and @Switch. The future of AI is now. 🔗 https://t.co/YfoT0z55qA

Lot of discussion on how much Meta is spending on new research hires. But Mark & Susan continue to refocus the co on their top / existential prios 5% employees = ~4K at 300K avg TC = $1.2B = 12 researchers at $100M / ea Meta cut ~4K employees this year in Feb and looking at

LOL this is an episode straight out of Silicon Valley. Funny to meme and read but no doubt in 1 yr it will be working The fact that this is not science fiction and is possible is 🤯 Hard for people to realize when they are riding on an exponential. Important to see the forest!
New Anthropic Research: Project Vend. We had Claude run a small shop in our office lunchroom. Here’s how it went.

Interesting Jensen quotes at GTC Paris: "we estimate around $1.5T of accelerated DC demand" "do believe most of the ASIC projects will end up getting cancelled" "We are going to sell hundreds of billions of GB200/300" "RTX Pro is the biggest opportunity ex GB" $NVDA

@ Snowflake Summit, @saranormous asked @sama what he'd do with 1000x more compute after trolling ("I'd use 1000x compute to train smartest AI model, then ask that model how it'd spend 1000x compute") he said "we see tons of use cases in chatgpt and inside enterprises using

$NVDA - Colette "On average Hyperscalers are deploying 1k GB200 NVL72 racks (72k GPUs) per week, and this rate is increasing" - run rate 4M GPUs a year and ramping... WAY higher (maybe 2-3x0 than what supply chain was estimating

I remember when Brad first came up with Invest America in 2021 and thinking, "this may be one of the most impactful things I can be apart of in my lifetime". I grew up in Queens, NY to an immigrant household. Went to public school. I'm incredibly fortunate to have been born in
The INVEST AMERICA ACT is included in the Reconciliation Bill. Every child born (3.7 M kids / yr) gets a private investment acct w $1000 in the S&P 500. Called “Trump Accts” in the Bill, they launch for all kids in 2026 w partial access at age 18 & full access at 35. 🇺🇸🚀🇺🇸
