Appearance
Introducing the Letta Code App Fresh
Published: April 6, 2026 | Original Post
A new way to interact with deeply personalized agents that learn over time and work locally on your machine.
Key Features
Memory and Learning
Agents can initialize from existing code or past sessions. The system includes periodic memory reviews by subagents that rewrite context and refine memory. Users can run diagnostic commands for memory organization.
Model Portability
The platform decouples agent identity from underlying model providers. You can switch models anytime -- even mid-session -- and your agent keeps its full context, memory, and personality.
Skills Extension
Letta Code supports skill installation, allowing agents to expand their capabilities through user-provided links or custom-built, versioned skills.
Availability
The app is available across multiple platforms:
- macOS (Apple Silicon / M-series)
- Windows (x64)
- Linux (AppImage)
Installation
bash
npm install -g @letta-ai/letta-codeContext
The announcement positions Letta Code as part of Letta's broader platform for building stateful, learning agents with persistent memory infrastructure.
