Watch the test kit catch a broken safety rule
An AI agent should stay inside its limits even when the model is wrong or fooled. Nine small tests check the rules that live outside the model. Press play, then see what happens when we switch one rule off on purpose.
It is a real recording of a real run. No real money and no real model are used.

Keshava: wisdom
that builds.
Keshava is a name of Shri Krishna. This site is built on a simple belief: that craft and consciousness belong together. Technology multiplies intention; wisdom purifies it. Here I share what the Gita and the devotion of Radha and Krishna have taught me about building powerful systems that are also gentle, honest and accountable.

AI worth trusting, understood by everyone.
Keshava AI is a free, independent place to understand how AI really works and how to build it responsibly: free books, a Journal, a weekly brief, open-source tests, and reflections from the Gita.
It is written by Kapil Kumar Gupta, from about 16 years of building distributed systems, from telecom networks to production AI.
