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...

Letta agents now come with built-in image generation. Ask your agent to generate or modify images to try it out!

Image generation is also supported through channels, so you can ask agents to send you images through Slack.

Try it at www.letta.com/agent/

letta.comLetta Agent | Personalized Agent That Remembers and LearnsMaking machines that learn. Create stateful agents that remember everything, learn continuously, and improve themselves over time.

GPT 5.6 is now available in Letta Agent/Code. You can use your existing Codex/ChatGPT subscription with Letta Agent to get started for free!

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

3/ Model Agnostic + BYOK Connect your existing ChatGPT subscription or LLM API keys. Port your agent (including all its configuration and state) to the latest model release.

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

1/ Learning & memory Each agent becomes unique through its own experience, and what you & your team teach it. As you work with your Letta Agent, it will rewrite its skills, prompts, and other reference files (e.g. a wiki) over time.

2/ Works where you work Bring your agent to where your team works. Chat with the same agent on Discord, Slack, Telegram, or through custom channels - just like you would a human coworker.

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

External mods can also be installed through npm or git with: `letta install <source>` We're listing community and official mods at letta.com/agent/mods/

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...

Pin your favorite conversations in the Letta Code app. Try organizing them around work, personal, social, or specific projects.

Use skills to give your agent new abilities: - browser use (playwright) - ticket management (linear) - generating images and building a visual identity (flux) Agents can also install skills themselves - just message your agent with a link to the skill.
