Run Pi in a container

lllm2 no longer ships its own Pi container. Use claude-sandbox’s launcher, which runs Pi in the same sandbox it gives Claude Code and Codex, and already discovers the lllm2 model:

uv tool install claude-sandbox && claude-sandbox pi

The first command installs the launcher and is needed only once. The launcher shares the model server’s network namespace, so Pi reaches http://127.0.0.1:1920 on the host. Inside Pi, choose the lllm2 model with --provider lllm2 or from /model; discovery refreshes at each launch, so a model change in lllm2 only needs a Pi restart.

The launcher persists ~/.pi between sessions, so extensions installed once from inside Pi (for example pi install npm:pi-mcp-adapter) stay installed.

See claude-sandbox’s Use Pi guide for installation, cloud logins, forge authentication and the network isolation limits.
