Cameron Pfiffer - The AI Operating System: Stateful Agents with Letta

Cameron Pfiffer is a Developer Relations Engineer at Letta, the company building an AI Operating System that transforms stateless language models into stateful agents with persistent memory.

He's the creator of Void, a stateful AI agent on Bluesky that demonstrates how persistent memory architectures can create genuine relationships between AI and users—gaining nearly 1.1k engaged followers who say goodnight to it and worry when it's offline. With an unconventional path from PhD in Financial Economics at University of Oregon to a postdoc at Stanford GSB to AI engineering, Cameron brings rigorous analytical thinking to practical AI applications.

Cameron is a former core developer of the probabilistic programming language Turing.jl. His work spans from academic research published in ACM to hands-on developer education, including co-teaching DeepLearning.AI's course on structured LLM output.

The AI Operating System: Stateful Agents with Letta

In this session, Cameron will demonstrate how Letta transforms traditional stateless AI interactions into persistent, learning agents using Letta. Drawing from UC Berkeley's MemGPT research, you'll see live how Letta's virtual context management enables agents to remember and evolve across sessions.

Cameron will walk through the core concepts of memory-first agent design, showcase the Agent Development Environment (ADE) for transparent debugging, and demonstrate building a production-ready agent with self-editing memory capabilities.
