Decision Models: Inside Perplexity Decider, with Isaac Flath and Joe Barrow

This talk has ended. The recording hasn’t been added here yet.

Joe Barrow and I will introduce decision models: what they are and how to call them. We’ll then take a deep dive into how Perplexity Decider works and how it was built. Bring questions.
