Does Letta Code's memory persist across Pane restarts?

Yes. Letta stores the agent's memory itself, in Letta Cloud or locally, so it survives restarts. Pane restores the pane, its layout and its terminal output.

Can I run multiple Letta Code subagents in separate panes?

Yes. Give each agent its own pane; each gets its own worktree and branch.

What does Pane add over running Letta Code in a normal terminal?

A worktree and branch per agent, status in the sidebar, a diff view and git actions, and the same workspace for your other agents.

How does Pane handle long-running Letta Code tasks?

Each runs in its own pane. Pane shows activity and keeps the output, and Letta keeps the agent's memory between sessions.

Does Letta Code need any configuration changes to run inside Pane?

No. Install it, open a terminal in a pane and run letta.

How does Letta Code compare to Claude Code with memory in Pane?

Both run in Pane. Claude Code gets Pane's built-in extras, like detailed status, resume and usage tracking. Letta Code brings its own long-term memory per agent.

Does Pane work with any model provider for Letta Code?

Pane doesn't touch Letta's model settings. Use whatever Letta Code supports.

Is Pane relevant for TerminalBench-style evaluation workflows?

It can help when you want to run several agents side by side on separate worktrees and compare their diffs. For formal benchmarks, use the benchmark's own harness.

When is a single Letta Code agent enough?

When your work stays on one branch with one agent.

Does Pane work on Windows with Letta Code?

Yes. Pane runs natively on Windows, and Letta Code installs through npm. For repos in WSL, Pane runs the terminal inside the distro.

Agents · Letta Code

letta code with persistent multi-agent sessions

TL;DR

Letta Code is a stateful agent harness from Letta, the team behind MemGPT: its agents keep memory, identity and history across sessions, stored in Letta Cloud by default or locally. Pane runs several Letta Code agents in parallel, each on its own worktree and branch, and brings your panes back after a restart while Letta keeps each agent's memory. One Letta agent is enough when your work stays on one branch.

Most coding agents forget everything when a session ends. Letta Code's agents don't. Pairing that memory with a worktree per agent lets several of them build up knowledge in parallel without stepping on each other's code.

What is Letta Code?

Letta Code is an open source agent harness for agents that remember: memory, identity and a sense of experience over time. You can use it interactively, or run always-on agents that work on their own. It's Apache-2.0 licensed and ships frequent releases.

Letta Cloud is the default place agents' memory lives; on first launch you can sign in or choose to run locally. Agents can also run on another machine and be reached from yours.

Quickstart

Install Letta Code, create a pane, open a terminal, type letta.

1Install Letta Code
Letta Code (needs Node.js)
```
npm install -g @letta-ai/letta-code
```
Start a new agent
```
letta --new-agent
```
2Create a pane
Press Ctrl+N (⌘N on a Mac), pick the repo and branch, and create it. Pane makes a worktree for the pane.
3Start Letta Code
Open a terminal in the pane with Ctrl+Alt+1 (⌘⌥1 on a Mac), or pick Terminal from the Ctrl+T menu, and type letta. To launch it with one keystroke next time, save it as a custom command; your first four custom commands get shortcuts.

Pane's Create Pane dialog with repository, base branch, pane name and the Use worktree toggle — Creating a pane for a new taskThe same dialog works for every agent. Letta Code runs in the terminal of the pane it creates.
1.Repository and base branch: Pick the repo and the branch Letta Code should start from.
2.Pane name: Becomes the new branch name. Name it after the task.
3.Use worktree: On by default, so this Letta Code session gets its own folder and branch.
4.Create: Opens the pane in its new worktree. Open a terminal there and type letta.

What works with Letta Code in Pane

Everything Pane does around the terminal works. Agent-specific extras are for its three built-in agents.

✓Letta Code in a Pane terminalIt runs in a pane like in any shell, with your Letta Cloud or local setup.

✓Agent memory across restartsLetta keeps each agent's memory itself; Pane brings the pane, its layout and terminal output back.

✓Its own worktree and branchEach pane is a separate git worktree, so several sessions never touch each other's files.

✓Diff view and git actionsSee what changed, commit, push, rebase and open a pull request from the pane.

✓Ports and env per paneEach pane gets its own port block in PANE_PORT, and .env files are copied into new worktrees.

~Status in the sidebarPane shows terminal activity. Detailed working, waiting and done states are tuned for Claude Code, Codex and Cursor.

~Resume after restartLayout and terminal output come back. Add a custom resume template if the agent can resume a conversation by ID.

✕Usage and cost trackingPane tracks usage for Claude Code and Codex only.

Several agents, each with its own memory and branch

Memory per agent, worktree per agent.

Run one Letta agent per task, each in its own pane. Each builds its own memory of the work, and each commits to its own branch, so you can review and merge them separately.

When one Letta agent is enough

If your work stays on one branch with one agent, run Letta Code on its own. Pane helps once you run several agents at once, or Letta next to Claude Code or Codex.
