In this tutorial, we demonstrate how to design a contract-first agentic decision system using PydanticAI, treating structured schemas as non-negotiable governance contracts rather than optional output formats. We show how we define a strict decision model that encodes policy compliance, risk assessment, confidence calibration, and actionable next steps directly into the agent’s output schema. By combining Pydantic validators with PydanticAI’s retry and self-correction mechanisms, we ensure that the agent cannot produce logically inconsistent or non-compliant decisions. Throughout the workflow, we focus on building an enterprise-grade decision agent that reasons under constraints, making it suitable for real-world risk, compliance, and governance…

A founding AI engineer at Delve, an AI startup based out of San Francisco, had been working all-nighters for three days straight. The techie was snapped hooked to his workstation, along with the co-founder having a chuckle. The Indian-origin MIT-graduate CEO, Mr. Karun Kaushik, shared the candid picture online, bragging about “this team never stops shipping,” until social media schooled him back. Anti-aging crusader and multi-millionaire entrepreneur Bryan Johnson slammed the boss with a tweet stating the following adverse impact of burning midnight oil: 3 all-nighters = impaired glucose metabolism, elevated cortisol, reduced BDNF, increased IL-6, shortened telomeres, cognitive decline,…

The mania around data centers has a lot of companies looking to become “picks and shovels” providers, by building profitable businesses that are ancillary to the gold rush gigs of selling server access or training leading AI models. MayimFlow, the Built World stage winner at this year’s TechCrunch Disrupt, is a good example. The startup is focused on essentially one task: preventing damaging water leaks. Data centers use a lot of water, and that water can present a big risk, even if a leak is small. Founder John Khazraee told TechCrunch that many data centers only have reactive solutions for…

Dutch entrepreneur Nalden, who co-founded the platform in 2009, says he’s deeply unhappy with changes made since Bending Spoons — a Milan-based tech firm known for buying and restructuring popular apps — acquired the service last year. “Bending Spoons doesn’t really care about people. Even though I get that it is their private equity strategy, I notice that since I left [WeTransfer] in 2019, there were a lot of updates that were basically killing the product,…
