Access stateful agents through any OpenAI-compatible interface. Run `letta server --openai-api` to chat with stateful agents through OpenWebUI, LibreChat, & more.
Opus 5 is now available in Letta! In our internal evaluations, we found that Opus 5: - Matches Fable in memory generation (rewriting memory and learning skills) - Significantly improves over Opus 4.8 in memory adherence and memory/skill usage
How can we learn across agent experience, when data is split across many different harnesses? We're releasing `trajectory`, an open-source package that normalizes agent sessions into one token-efficient format designed for agents learning from past experience. www.letta.com/blog/trajec...
Trajectory: A Standard Format for Agent Experience Data
Introducing trajectory, an open-source package that normalizes coding-agent sessions from Claude Code, Codex, Letta Code, and other harnesses into one token-efficient format designed for agents learning from past experience.

The distributed agent era is here. Run agents programmatically on cloud sandboxes or any registered remote (running `letta server`). Memory & context moves with agents across machines.
Letta Agent is the easiest way to add persistent, digital coworkers to your team. Each agent: - is teachable and customizable - never forgets - works with your whole team (not just you) - runs locally & on remote machines Available on MacOS/Linux/Windows
Agents can now not only rewrite their memory, but also rewrite the execution code they run in (the harness) through Mods. Mods (inspired by Pi's extension system) allow for harness-level changes like: - modifying context - injecting custom tools - customizing the statusline

We red-teamed the Context Constitution to test whether frontier models can preserve agent memory, identity, and continuity under pressure. Models are improving, but many still default to ephemerality. The model is ephemeral. The agent is not. www.letta.com/blog/red-tea...
Red-teaming the Context Constitution: Auditing models as experiential AI agents | Letta
We evaluate how well models perform for driving agents that have identity, long-lived experience, and the capability to self-evolve. We find that models are still limited by a deep self-identification...
