Agents and Claude Delhi, what a room. 🙌🏼

120 builders showed up ready to talk agentic AI, and the energy matched it.

🔹 @rudrank on Fable 5 and why judgement is the feature
🔹 Rishit Gupta on loop engineering
🔹 Shaurya Singh on going from one engineer to one startup to zero Union on Claude Cowork use cases for productivity

Add in demos, an afternoon showcase, and hours of hallway conversations with people building across AI, dev tools, research, and startups; and honestly, this is why we do these.

Delhi's AI community keeps showing up, and it keeps getting better.
