@demishassabis @GoogleAIStudio Well done Gemini Flash! The extremely sharp @perplexity_ai Ceo agrees. 👏 youtu.be/Xwjr_jxGFG8?t=…

Our most expressive and steerable TTS model yet! Designed to give builders granular control over AI-generated speech, Gemini 3.1 Flash TTS is really fun to play with! Available in preview today - for devs via the Gemini API & @GoogleAIStudio + for enterprises on Vertex AI

Not all Unrealized Gains are equal 🍀 Let winners run vs Trim a little vs Trim your principle out!

$Nvda + $Googl 📢

@vikramskr @AMD ceo agrees! 👏 "Inference token consumption increased 100x over the last two years. We are only in the early innings of agentic AI that uses multiples of inference tokens that simple queries use."

I have removed paywalls from my most successful post in terms of readership and paid conversion ever. CPU shortages in agentic AI, and the upcoming Intel earnings call is good enough reason to do so. I also want to provide a sample of the kind of reports available to paid subscribers on my Substack. Enjoy! open.substack.com/pub/viksnewsle…

@semidoped @Austinlyons @Meta So good - your Matt Steiner @Meta drill down! ⛳ Next perhaps a discussion with the also in-the-know @AristaNetworks folks! youtu.be/F5PhIDy_yEs?t=…

Meta's core business is ads. Ads are AI workloads. But not LLM workloads. @austinlyons chatted with @Meta VP Matt Steiner to understand Meta's heterogeneous compute stack. Surprises: - Recommender training needs a different compute-to-memory ratio than LLMs. Hence MTIA. - Retrieval is memory-bound at Meta scale. Andromeda runs on a co-designed Grace Hopper SKU, not off-the-shelf. - Adaptive ranking scales compute per user. Power users with long histories get more. - Consolidating N ranking models into one (Lattice) improved performance, not just cost. - KernelEvolve (LLM-written kernels) flipped heterogeneous fleet economics. SWE demand going UP. - Meta wants ~100x more kernels per chip.

@PhotonBull Thought Arista Networks XPO solves the "thermal wall" faced by 800G and 1.6T transceivers, liquid cooled ports with direct "no air gap" connections?

Everyone is watching $LITE, $COHR, $AAOI, $AXTI run. The photonics rotation is real and the AI capex thesis is well understood by now. What isn't talked about enough is what comes after 800G. Silicon photonics (what most of the above ship today) and InP both hit hard physical limits beyond 800 Gbps. The AI buildout doesn't stop there. Nvidia's NVLink 6 is already targeting 3.6 Tb/s per GPU. The whole stack has to move to 1.6T then 3.2T. Current materials can't get you there cleanly. That's where TFLN comes in. Thin-film lithium niobate isn't a new material, LN has been in telecom for 60 years. What changed is the fabrication. A smart-cut process now lets you bond a nanometer-thin film of LN onto a substrate, giving you all the electro-optic properties of the crystal in a form dense enough to build photonic integrated circuits. The result: modulators running 100+ GHz bandwidth, sub-1V drive voltage, and propagation loss under 0.1 dB/cm. Silicon works by pushing carriers around to change the refractive index. TFLN uses the Pockels effect, the field changes the index directly, no carriers, no lag, no extra heat. That's a generational gap in performance at the speeds AI infrastructure needs. TFLN doesn't replace InP either. It needs a laser source from InP or a VCSEL. It sits on top of it. The problem is supply. Nearly all TFLN wafers in the world come from one company: NANOLN, based in Jinan, China. Raytheon literally said this out loud in their Mastermind AFRL contract filing. They described TFLN wafer production as dominated by a Chinese manufacturer and selected Gooch & Housego ($GHH, LON) to build the first domestic US production line in Ohio. CPO (co-packaged optics) is the architecture pulling this forward. CPO integrates optical engines directly onto the switch or GPU package, cutting signal loss and power vs pluggable modules. CPO ports are forecast to be 30%+ of all 800G and 1.6T deployments in 2026-2028. At those speeds the modulator of choice converges on TFLN. The stack is: hyperscaler capex -> CPO adoption -> 1.6T modulator demand -> TFLN wafer supply crunch -> whoever controls domestic production. $AXTI is the InP layer. $GHH is the TFLN layer. Same thesis, different spot. $GHH is a London-listed, small cap, and illiquid. Not a momentum trade. But if the CPO buildout plays out the way the optical interconnect market is projecting, the wafer supply chain gets stress-tested, then this Western producer with a Raytheon-backed production line looks very different at that point. On top of that, $GHH is an undervalued, profitable and growing aerospace/defense/life sciences/telecom/industrial supplier. Small position, long time horizon, high conviction on the structural setup.

Arista networks' xpo technology with liquid cooling of transceiver ports with no air gap is important! 🎖

NYC's government-run grocery store is expected to open in 2029 at a $30M cost to taxpayers More charts: a16z.news/p/charts-of-th…

The US 🇺🇲 is now the world’s top energy superpower: #1 Oil: 13.6 million barrels per day. #1 Petroleum product exports: 7.2 mbpd #1 Crude oil exports: 5.2 mbpd #1 Liquids production: more than Saudi Arabia + Russia combined #1 Natural gas: More than Russia + Iran + China combined #1 Nuclear producer: about 30% of global nuclear generation Global leader in renewable electricity generation, hydro and coal output. Diversification and security are not ideology, it is logic.

The inflation story in one chart: Where government spending and subsidies are highest, prices rise the fastest. Where competition is highest, prices fall.

One of the great political moves by the left in recent years has been convincing a large portion of America that "the rich" don’t pay taxes and it’s all poor people, when the exact opposite is true. The Top 1% pay 46% of all income taxes. The Top 10% pay 76% of all income taxes.
