Guests, each with their stance on renting or owning models: rent until it hurts, rent then own, ride each new model, own the models, own for margin, and match the model to the task.

Signalful Analysis

From interviews with Gabe Pereyra of Harvey, Misha Laskin of Reflection AI, Gabe Stengel of Rogo, Cliff Obrecht of Canva, Alex Mashrabov of Higgsfield, Mike Cannon-Brookes of Atlassian, Anish Acharya of Andreessen Horowitz and Daniel Dines of UiPath

Canva cut its AI costs by about 90% by training its own models. Harvey spends hundreds of millions of dollars a year running AI models and tells application companies to rent closed ones until the bill forces them to train their own. Opposite moves, one question: should an AI product run on rented models or its own?

Builders give three answers: rent the best model and ride each release, own the model for margin, or match the model to the task. A task worth thousands of dollars justifies the most expensive model on offer. Routine work at volume does not.
