Stateful AI Employees, Not Amnesiac Bots: Why We Build on Letta Code, the Best Agent OS

If you want an AI employee instead of a clever bot that forgets you every morning, the foundation matters more than the model. Claude Code and Codex are remarkable and amnesiac: every session starts from zero. Letta Code does not. It is a stateful agent operating system that persists across sessions, learns your business, writes its own skills, and carries its memory across machines and even across model generations. This is a sourced, head-to-head look at Letta Code versus Claude Code, why people are buying dedicated mini PCs just to keep agents running, why Letta Code is the best agent OS we have found, and how we turn it into stateful AI employees your business can actually depend on.
