frontier labs are investing heavily in mechanistic interpretability to understand what’s happening inside neural networks.

we wanted to make these concepts more accessible to people who want to work on the same problems.

our latest release on @TensorTonic lets you build -

> sparse autoencoders from scratch
> inspect the features they learn
> test them through interventions.

At 38, I had 17 years of program management under my belt. PgMP, PMP, enterprise SaaS. Zero machine learning experience. At that time, as everyone does, I started doing some Coursera courses but everything was vague. There were two things that helped - @karpathy and @rasbt. Once the concepts were broken down - I could build, break, and eventually come up with 100s of ideas that failed.

I decided to pivot into AI research. Not a side hobby. A real pivot. I spend to this day at least a few hours every week reading latest papers and trying to break the implementation of the paper. Even now, I am participating in the ICLR huggingface paper reproduction challenge.

Two years later at 40: 6 papers on arXiv, an NVIDIA Inception membership, founded Murai Labs, and an open source Tamil language model that is coming out soon. The book grew directly out of what I needed to build TamilLM from scratch. If it helped me learn how to ship a real model with no ML background, it can help you too. It is such a beautiful coincidence that TamilLM finished pretraining and Under The Hood launched on Amazon on the same day - it was not planned. (Kadavul irukaan Kumaru moment)

Meet Maitrai Maka, who graduated as batch topper in Ocean Engineering and Naval Architecture from IIT Kharagpur in 2017, and started building autonomous ships and submarines before he'd even left campus behind.

He founded Rekise Marine that same year out of Bengaluru, alongside Rear Admiral Shekhar Mital (Retd), betting that future maritime power would run on low cost autonomous systems instead of massive manned fleets. No hype cycle backed him. Defence tech in India barely had a seed-stage playbook back then ye he built anyway.

Rekise designed the vessel, its sensors, and its software as one integrated system rather than bolting pieces together later, working in-house with shipyards like Goa Shipyard Limited and GRSE Limited. Two vessels, Jaldoot and Swadheen, were already delivered and had completed fully autonomous open sea trials.

In June 2026, 9 years into building, that groundwork pulled in $9.7 million in seed funding, co-led by Accel and Nikhil Kamath's NKSquared. The capital now funds Jalkapi, an 11-metre, 20-tonne autonomous submarine built for missions lasting up to 45 days.

Reliable autonomy at sea starts with refusing to separate the hardware from the intelligence.

my weirdest conspiracy theory is that the global ethanol push is far more coordinated than people realize.

the US is pushing e15. brazil has been aggressively expanding e27. india has already committed to e20 & is talking about going higher. much of southeast asia is moving toward e20. many latin american countries are already at e30. even europe continues to expand ethanol blending mandates.

somehow countries with completely different politics, economies and energy priorities all arrived at the same conclusion which was to push for a fuel that's anti-vehicle, kills the engines of your cars and eats away its rubbers.

on one hand this looks like a global movement being driven by big biofuel, which ironically also has every leading oil name invested in it. on the other it also looks like a movement to take away your autonomy

I taught JEE physics for years. That paper breaks strong kids in three hours.

This exam is five hours of theory and five hours of lab work, and these five did close to perfect scores on it.

Let me tell you what actually happened.

The International Physics Olympiad is the world championship of school physics. It was the 56th edition. Held in Bucaramanga, Colombia, from July 5 to 12.

381 students. More than 85 countries. Every one of them the best physics student their country could find.

India sent five kids.

All five came back with gold.

Their names are Kanishk Jain from Pune. Riddhesh Anant Bendale from Indore. Rishit Garg from Dwarka in Delhi. Shresth Suraiya from Mumbai. Svarit Joshi from Ahmedabad.

We know a hundred cricketers by their nickname and not one of these boys. :)

That clean sweep put India at joint World Number One. Tied with China, Russia, Kazakhstan, South Korea and Taiwan.

Those are countries that pour serious money and national pride into science education. We are standing level with them.

Now here is what the exam actually was.

Two papers. Each five hours long.

The theory paper had three problems. One on the thermodynamics of paramagnetic cooling. One on the photoionisation of ozone. One on the dynamics of electron positron pairs.

The experimental paper was another five hours in a lab, working through heat transfer and thermodynamic processes in fluids.

That means you get given equipment you have never seen, and you have to design your own experiment, take your own readings, handle the errors, and reach a real answer.

Not multiple choice. No shortcuts. No pattern recognition. You either understand physics or you sit there for five hours.

HBCSE says the Indian students were near perfect on theory and excellent on the practical too.

Now, this was India's 27th appearance at the IPhO.

Across all those years, about 44 percent of Indian students have won gold, 41 percent silver, 10 percent bronze.

In the last ten years, every single Indian student has come home with a medal. 62 percent gold, 38 percent silver.

Not one kid has gone and come back empty handed in a decade.

Five golds in one year has happened only twice. This year, and in 2018.

So who built this.

The programme is run by HBCSE, the Homi Bhabha Centre for Science Education. It sits under TIFR, which sits under the Department of Atomic Energy.

They run the whole funnel. A national exam, then a national olympiad, then a brutal selection and training camp, and out of everyone in the country, five kids get on a plane.

The team was led by Professor Anwesh Mazumdar of HBCSE-TIFR and Dr Leena Joshi from St Xavier's College, Mumbai.

The scientific observers were Professor Ananda Dasgupta from IISER Kolkata and Nisha Kelkar from Gogate-Joglekar College in Ratnagiri.

Yes. Ratnagiri. A college in a small coastal town in Maharashtra.

This is public education doing something the private coaching industry could never do on its own.

The coaching industry is very good at one thing. Teaching you to solve a known problem fast.

That is what JEE and NEET reward, and I say that with love because I was part of that world.

But an olympiad paper does not have a known type. There is no shortcut chapter. There is no formula sheet that saves you. You have to sit with a problem you have never seen and think.

That is a completely different muscle. And a government funded centre has been quietly building it in Indian teenagers for 27 years.

So yes, be proud. Loudly.

HBCSE also shared that around 64 percent of India's olympiad medallists go on to do a PhD.

But only about 32 percent of medallists end up settling in India.

I do not say that to spoil the moment. These kids owe the country nothing. They earned every option they have.

But it should tell us something. We are excellent at finding this talent. We are excellent at training it. We are still not great at giving it somewhere worth staying.

Congratulations Kanishk, Riddhesh, Rishit, Shresth and Svarit. This is one of the best things an Indian did this year and most of the country will never hear about it.
