When mathematicians enter other domains, they solve it. The most popular example of that is Jim Simons and Renaissance Technologies "solving" algorithmic trading to a large extent. Now we are entering an arena where mathematicians are looking for a new home as AI is encroaching theirs. Extremely interesting times as I expect multiple hard real world problems to be solved by them over the next few years. When theory stops being exciting, great practical things would be achieved. We at @PramaanaLabs are one such group of mathematicians, betting that the next wave of hard, real-world problems gets solved by people who think in proofs. We are actively speaking with more mathematicians, and the hunger and energy are unmistakable. If you are one, reach out. Let us talk about what we could build together. @krishnan_rag @sanjaygsub


The debate around artificial intelligence (AI) has reached the Supreme Court of India after a National Company Law Tribunal (NCLT) reportedly relied on fake precedents and cases generated using the tech. The top court set aside an NCLT judgment as it found that the tribunal had believed "non-existent, fake and hallucinated judgments/precedents" generated using AI, news agency PTI reported. The Supreme Court bench which heard the case comprised Justices PS Narasimha and Alok Aradhe. Read Here:dnaindia.com/india/report-s… #SupremeCourt #AI #DNAUpdates

Math proofs are cool, but the real revolution? Verifying real-world claims in accounting, tax law, compliance, medicine & more; reliably, efficiently, and at scale. Proof trees look different across domains. One-size-fits-all won't cut it. AI prover architectures must be purpose-built to navigate the specific reasoning trees, resource constraints, and rule stability of the environment they are verifying.

Medical AI is rushing toward autonomous agents. But in the clinic, a fluent reasoning trace isn’t enough. We need proofs that are machine-checked and respects every inclusion, exclusion, and contradiction in the patient’s data. Introducing the architecture of clinical truth: formalizing diagnostic criteria in Lean 4 so every diagnosis is verifiable. No more unsafe shortcuts.

We have been working on structural type systems and verifiable code. Best wishes to Pramaana Labs team! I am very happy to see cutting edge R&D in India. Using these approaches, I believe far more efficient as well as highly reliable AI systems are possible. That is also why I fundamentally don't agree with the trillion dollar bets being made but that is a separate topic.


Today, I'm thrilled to announce Pramaana's $27M seed, led by @khoslaventures. The foundational domains that hold the world together: tax, law, finance, healthcare; all run on certainty. Probabilistic AI can't give them that. We’ve been asked to accept wrong answers with AI as ‘hallucinations’, while in traditional software terms, it’s just a bug. And a wrong answer in such mission-critical domains is more than just a bug, it's a liability that could have catastrophic impact. We built Pramaana to deliver a 100% trustable experience to the domains that run on certainty: AI that is provably correct, not probabilistically correct. We turn statute and regulation into machine-verifiable code, so every output ships with mathematical proof of correctness. Our mission is to make AI take ownership of it’s work. Pramaana in Sanskrit stands for “means of valid knowledge”, and we’re going to achieve that by formalizing the world’s knowledge.

Nine years at Google, three on Gemini at DeepMind, working on post-training with people I'd follow anywhere. Close enough to scale to see how far it goes, and where it stops. Today's AI is remarkable, but jagged: it hallucinates fluently. In high-stakes domains like healthcare, legal, or finance, a confident mistake is worthless. Right as I was wrestling with this, @krishnan_rag , @ranjan_vittal and I converged on a wild idea: AI that proves its own work. Proofs, not disclaimers. So I left. Nine months later, at Pramaana Labs, we're building it: a cracked team training foundation models to formalize human knowledge on a scale hitherto undreamt of, and bring formally verified AI to the real world. A future where AI is provably correct, not just probably.

Not many launch videos are this inspiring-- feeling like the future is getting brighter thanks to @ranjan_vittal and team's formal AI verification for real-world domains. Congrats to @PramaanaLabs on the seed raise! Proud to back such a visionary team.

Announcing our investment into @PramaanaLabs, an AI Lab for Formal Verification to formalise real world domains like tax, legal, healthcare & other mission critical domains where truth matters Congrats @ranjan_vittal @krishnan_rag @sanjaygsub Let’s Build On Large Dreams

Nexus is proud to back @PramaanaLabs in their $27M seed round! Congratulations @ranjan_vittal, @sanjaygsub, Krishnan Raghavan & team! @b_jishnu | @746watt

We are thrilled to back @PramaanaLabs! As AI takes on more important work, trust can’t depend on a human checking every answer. Pramaana is building the capability to make AI outputs verifiable by design; this is a BIG step toward safer, more capable, and more useful AI. And with the right leadership in @ranjan_vittal, @krishnan_rag, @sanjaygsub and team @PramaanaLabs cc @khoslaventures @vkhosla

Last week @vkhosla anchored our summit. Injured, when stepping back would've been expected, he showed up and turned it into an example of how verification can transform healthcare. The conviction he brings to every founder, no matter how small the company, is humbling. The GOAT.

Auto formalization will be an important new area.
