In this crossover episode of Inference by Turing Post, host Ksenia Say interviews Dev Rishi, CEO and co‑founder of Predibase, about the shift from static, one‑time trained models to continuously learning systems. Rishi explains Reinforcement Fine‑Tuning (RFT) – a technique that uses tiny labeled datasets plus reward functions to fine‑tune models – and how Predibase is building pipelines that collect production traffic, apply RFT, and close the loop for online improvement. The conversation expands to the broader vision of practical specialized intelligence versus AGI, the early‑stage but brittle nature of agentic workflows, and the technical and operational challenges of inference at enterprise scale. Rishi highlights recent advances in open‑source LLMs, gaps in the open‑source stack (especially robust evaluation), and Predibase’s roadmap (data collection features, Direct Preference Optimization, multimodal support). He also shares personal reflections on product‑first leadership, the rapid pace of AI research, concerns about hype bubbles, and a book that shaped his thinking – The Happiness Advantage. Throughout, Nathan Labenz frames the episode, promoting the podcast and its sponsors.
