Shemesh

A private, frontier-grade coding & reasoning model — drop-in for Claude Code, no VPN required.

1 Get your key

Ask Lior for the shared API key (starts with sk-aitken-…). Keep it private.

2 Run the installer

Paste this in your terminal, replacing YOUR_KEY:

curl -fsSL https://shemesh.liorruba.com/install.sh | bash -s -- YOUR_KEY

It checks your key, installs the Claude Code CLI if needed, and adds a shemesh command. Your normal claude is left untouched.

3 Start coding

cd your/project
shemesh

shemesh launches Claude Code against the Shemesh model. That's it.

🧩 Using VS Code?

With the Claude Code extension installed, open VS Code's built-in terminal (Terminal → New Terminal) and run this once:

curl -fsSL https://shemesh.liorruba.com/vscode.sh | bash -s -- YOUR_KEY

Then reload: Cmd/Ctrl+Shift+P → Reload Window. Claude Code in VS Code now uses Shemesh.

Prefer to do it by hand?

Create ~/.claude/settings.json (or add to it):

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://shemesh.liorruba.com",
    "ANTHROPIC_AUTH_TOKEN": "YOUR_KEY",
    "ANTHROPIC_MODEL": "shemesh",
    "ANTHROPIC_SMALL_FAST_MODEL": "shemesh"
  }
}

Reload VS Code afterward. To undo, remove the ANTHROPIC_* lines.
