Letta Office Hours is a public video series about the changing architecture and practice of persistent AI agents. These guides turn each recording into a compact, timestamped explanation of its major announcements, demonstrations, questions, and design connections.
The pages are historical records, not current product manuals. Letta changes quickly; a feature described in an older episode may have been renamed, redesigned, removed, or absorbed into a different surface. The original recording remains the primary source for what was said at that time.

Recurring themes
Persistent identity and memory. The series repeatedly separates an agent from any one chat window, model call, or client application.
Execution surfaces. Letta Code, Desktop, Chat, channels, sandboxes, schedules, and the Agent SDK appear as different ways to connect durable agents to work.
Harness extension. Skills, tools, MCP, mods, protocols, and provider compatibility are treated as different layers rather than synonyms.
Inspectable state. Memory files, commits, runs, approvals, traces, and tests make agent behavior reviewable instead of merely fluent.
Teaching and evaluation. Later episodes increasingly ask how agents learn from trajectories, specifications, feedback, and explicit release gates.
