Finetuning: 500m AI agents in production with 2 engineers — Mustafa Ali & Kyle Corbitt

Video Description

Method Financial has run AI financial agents in production for over 18 months, handling hundreds of thousands of interactions daily. In this talk we'll review some of the "battle scars" we gained while deploying and scaling this system. We'll discuss specific techniques we've found critical to keeping this system operational and effective including fine tuning, realtime guardrails and "sanity checks", observability platforms, and intelligent caching.
