- Packages all agent components: system prompts, editable memory blocks, tool configurations, and LLM settings
- Cross-framework portability — agents can be seamlessly migrated and deployed between compatible systems
- Multiple import/export methods: Python SDK, TypeScript SDK, REST API, and ADE GUI
- Supports agent versioning and state snapshots for collaboration and archival
- Includes a curated directory of pre-trained agents ready to use or contribute
Use Cases
💡 Export trained agents and share them with your team or the community
💡 Migrate agents between different AI frameworks for cross-platform deployment
💡 Version control agent configurations and track change history over time
💡 Quickly deploy pre-trained agents to a Letta Server via ADE, SDK, or API
💡 Use the ADE visual interface to import and export agent state with ease
