Platform for stateful agents: AI with advanced memory that can learn and self-improve over time.

What it solves

Letta 提供了一種方式來構建具備先進記憶功能的 AI 代理，這些代理能隨時間學習並自我改進，突破標準短期上下文窗口的限制。

How it works

Letta 允許開發者建立保持持久記憶區塊（例如人格與人類細節）的有狀態代理。它與模型無關，且可透過 CLI 工具用於本地任務，或透過 Python 與 TypeScript SDK 的 API 進行應用整合。系統支援使用技能與子代理來增強代理能力。

Who it’s for

想要在應用程式中整合有狀態、可自我改進的 AI 代理，或在終端機本地執行自主代理以協助程式編寫與一般電腦任務的開發者。

Highlights

  • Advanced Memory: Enables agents to learn and maintain state over time.
  • Model Agnostic: Works with various LLMs, including recommendations for high-performance models like Opus 4.5 and GPT-5.2.
  • Flexible Deployment: Offers both a local CLI for terminal-based agents and a full-featured API for app development.
  • Extensible: Supports the addition of skills and subagents for complex workflows.
