How Lawyers Built Frontier Plugins for OpenAI

What happens when OpenAI asks practicing lawyers to help build a canonical set of legal plugins for the OpenAI for Law launch?

In Episode 1 of the LegalQuants Podcast, Victor Wang joins Jamie Tso and John Hughes to unpack how the team turned legal expertise into working plugins in just a few weeks. They share the ambitious first idea, the feedback that changed their approach, and what it takes to build something lawyers will actually use.

In this conversation, we discuss: 1. How a small WhatsApp group brought together lawyers who had been building alone—and became LegalQuants. 2. Why OpenAI pushed the team beyond an all-purpose “skill creator” toward concrete, customizable legal workflows. 3. How marketplace discovery changed the product: organize around litigators, transactional lawyers, and lawyers learning AI. 4. What makes a flagship skill: a real practice problem, a clear “aha” moment, testing with real documents, and a way to work with other skills. 5. How cite-checking, diligence, and redlining fit into larger acquisition, litigation, and negotiation workflows. 6. Why a legal AI skill needs a clear purpose even after the next model gets better. 7. Where to start: try a skill on work you understand, use legal design to make complex material easier to navigate, and feed what you learn back into the project. 8. Why Jamie sees legal quants becoming an internal capability at law firms—and what the Residency is building toward.
