Use Cases & Benefits
- Implements stateful AI agents with persistent memory, identity, and learning capabilities across coding sessions.
- Enables continuous learning and memory retention across sessions, unlike traditional stateless coding assistants.
- Use for building AI coding assistants that improve and adapt over time with project-specific knowledge.
- Use for integrating multi-model support to leverage different LLMs like Claude, GPT-Codex, and Gemini seamlessly.
- Use for creating personalized developer tools that remember context and skills across multiple development sessions.

From the README
Letta Code is a memory-first coding harness, built on top of the Letta API. Instead of working in independent sessions, you work with a persisted agent that learns over time and is portable across models (Claude Sonnet/Opus 4.5, GPT-5.2-Codex, Gemini 3 Pro, GLM-4.7, and more).
Read more about how to use Letta Code on the official docs page.
Install the package via npm:
Navigate to your project directory and run
letta(see various command-line options on the docs).Run
/connectto configure your own LLM API keys (OpenAI, Anthropic, etc.), and use/modelto swap models.Letta Code is built around long-lived agents that persist across sessions and improve with use. Rather than working in independent sessions, each session is tied to a persisted agent that learns.
