It runs the same model-group discovery as above, splits the results into chat-capable and embedding-capable pools, and asks you to assign one or more models from the chat pool to each of the four complexity tiers -- SIMPLE, MEDIUM, COMPLEX, REASONING. Each tier's picker is a type-to-filter fuzzy search (fzf-style) rather than a scrollable numbered list, so it stays usable even with hundreds of model groups: type a substring to narrow the list, tab to toggle a model into the selection, enter to confirm (assigning more than one model to a tier is exactly when this matters -- complexity_router picks randomly among a tier's pool per request, and adaptive mode specifically depends on having more than one candidate to choose from). From there it optionally offers: classifying prompt complexity with an LLM (again picked from your discovered pool) instead of the free built-in heuristic scorer, semantic keyword matching for tier assignment (needs an embedding model from the pool), and adaptive (bandit-based) selection layered on top of tiering. + +The wizard writes the result to `~/.litellm/autorouter/config.yaml` with `0600` permissions, since the file embeds your real proxy API key. Every model referenced anywhere in that config -- tier targets, the classifier model, the embedding model -- becomes its own `litellm_proxy/` deployment whose `api_base` and `api_key` point back at your real proxy. That is the trick that keeps your real proxy's config untouched: every actual network call this generates, whether it is the routed completion, an LLM-classifier call, or an embedding call, forwards transparently through your real, already-running proxy with your real key. + +You do not need to tell Claude Code to request `autorouter` by name yourself: `lite autoroute up` also sets `ANTHROPIC_DEFAULT_SONNET_MODEL`, `ANTHROPIC_DEFAULT_HAIKU_MODEL`, and `ANTHROPIC_DEFAULT_OPUS_MODEL` to `autorouter` in `~/.claude/settings.json`, so every one of Claude Code's own model tiers requests it directly regardless of `/model` or whatever it defaults to otherwise. (A bare `model_name: "*"` deployment looks like the obvious way to catch any request instead, but litellm's Router looks up auto-router deployments by the literal requested model string with no wildcard resolution, so a `"*"` entry would never actually match real traffic -- these env var overrides are what makes it work.) + +You must run `configure` at least once before `up`; running `up` first fails with a clear error telling you to configure first. + +#### Launch the Ephemeral Auto-Router Proxy + +```bash +lite autoroute up +``` + +Starts a local, throwaway litellm proxy on a random free port, running the config `configure` generated, with a freshly-minted random API key baked in for this session only (your real proxy key never leaves the generated config -- it only appears there, forwarding to your real proxy). It waits for the ephemeral proxy to report healthy, then patches `~/.claude/settings.json` the same way `lite up` does, except with a static `ANTHROPIC_AUTH_TOKEN` env var instead of an `apiKeyHelper`, since this key is short-lived and self-issued rather than something needing SSO refresh. Any `claude` session started afterward, from any terminal, routes through the ephemeral proxy. + +`lite autoroute up` runs in the foreground and streams the ephemeral proxy's own log file into your terminal, so you can watch its routing decisions -- which tier and model got picked for each request -- as you use Claude Code normally. Press Ctrl-C (or send SIGTERM) to stop it; this kills the child proxy process and restores your original Claude Code settings, in that order. + +#### Recover From an Unclean Shutdown + +```bash +lite autoroute down +``` + +If the `lite autoroute up` process dies uncleanly -- `kill -9`, a crash -- rather than being stopped with Ctrl-C, `down` is the manual recovery path: it kills any leftover ephemeral proxy process found via a recorded pid file and restores Claude Code's settings from whatever backup is on disk. + +#### Example + +```bash +lite autoroute configure +lite autoroute up +# use Claude Code as normal in another terminal; routing decisions stream live +lite autoroute down # only needed if `up` was killed uncleanly instead of Ctrl-C'd +``` + +#### Caveats + +Adaptive mode's learned state does not persist across `lite autoroute up` sessions -- there is no local database, so every session starts adaptive selection cold. A Claude Code session already running before `up` started, or still running when it stops, keeps whatever settings it loaded at its own startup; like `lite up`, this is a one-time file patch and restore, not a live traffic interceptor. Only Claude Code is supported, for the same reason as `lite up`: no other supported agent (for example Cursor) has an equivalent hot-patchable config file. + +A session that outlives `up` (or is still running the moment you stop it) keeps sending requests, master key included, to that now-freed loopback port until you restart it. Once the ephemeral proxy process exits, nothing stops another local account on the same machine from binding that same port and receiving those requests instead -- unlike `lite up`'s `apiKeyHelper`, which is re-resolved per request, `autoroute`'s master key is a static value, so whoever receives them gets a live-looking token along with the prompt content. Restart any Claude Code session before you consider the machine clean, run `lite autoroute down` promptly rather than leaving a stopped session's settings patched, and do not run `lite autoroute up` on a shared or multi-tenant host. + +Do not run `lite up` and `lite autoroute up` at the same time. Each patches `~/.claude/settings.json` and keeps its own separate backup, with no coordination between them: whichever one you stop or crash out of last is the one whose backup gets restored, which can silently leave the *other* mode's settings (a static master key and a now-dead loopback URL, or a stale `apiKeyHelper`) active. Run `lite down` or `lite autoroute down` (whichever applies) before switching to the other mode. + ## Environment Variables The CLI respects the following environment variables: diff --git a/litellm/proxy/client/cli/commands/agents.py b/litellm/proxy/client/cli/commands/agents.py index dfcedb70686..6b6252d8ecb 100644 --- a/litellm/proxy/client/cli/commands/agents.py +++ b/litellm/proxy/client/cli/commands/agents.py @@ -212,7 +212,7 @@ def _is_interactive() -> bool: return sys.stdin.isatty() -def _resolve_api_key(ctx: click.Context) -> str: +def resolve_api_key(ctx: click.Context) -> str: base_url = ctx.obj["base_url"] api_key = ctx.obj.get("api_key") if api_key: @@ -238,7 +238,7 @@ _SKIP_VERIFY_HELP = "Skip the pre-launch key check against the proxy." def _launch(ctx: click.Context, binary: str, args: Sequence[str], *, skip_verify: bool) -> None: base_url = ctx.obj["base_url"] started_interactive = _is_interactive() - api_key = _resolve_api_key(ctx) + api_key = resolve_api_key(ctx) display_name, _ = agent_profile(binary) click.echo(f"litellm: routing {display_name} through proxy at {base_url.rstrip('/')}") @@ -288,5 +288,6 @@ __all__ = [ "agent_launch_args", "verify_proxy_key", "agent_profile", + "resolve_api_key", "AgentRunError", ] diff --git a/litellm/proxy/client/cli/commands/auth.py b/litellm/proxy/client/cli/commands/auth.py index 4eda6817252..61495403407 100644 --- a/litellm/proxy/client/cli/commands/auth.py +++ b/litellm/proxy/client/cli/commands/auth.py @@ -72,7 +72,7 @@ def display_teams_table(teams: List[Dict[str, Any]]) -> None: console = Console() if not teams: - console.print("❌ No teams found for your user.") + console.print("No teams found for your user.") return table = Table(title="Available Teams") @@ -162,7 +162,7 @@ def display_interactive_team_selection(teams: List[Dict[str, Any]], selected_ind # Clear the screen using Rich's method console.clear() - console.print("🎯 Select a Team (Use ↑↓ arrows, Enter to select, 'q' to skip):\n") + console.print("Select a Team (Use up/down arrows, Enter to select, 'q' to skip):\n") for i, team in enumerate(teams): team_alias = team.get("team_alias") or "N/A" @@ -184,7 +184,7 @@ def display_interactive_team_selection(teams: List[Dict[str, Any]], selected_ind # Highlight the selected item if i == selected_index: - console.print(f"➤ [bold cyan]{team_alias}[/bold cyan] ({team_id})") + console.print(f"> [bold cyan]{team_alias}[/bold cyan] ({team_id})") console.print(f" Models: [yellow]{models_str}[/yellow]") console.print(f" Budget: [blue]{budget_str}[/blue]\n") else: @@ -220,15 +220,13 @@ def prompt_team_selection(teams: List[Dict[str, Any]]) -> Optional[Dict[str, Any # Clear screen and show selection console = Console() console.clear() - click.echo( - f"✅ Selected team: {selected_team.get('team_alias', 'N/A')} ({selected_team.get('team_id')})" - ) + click.echo(f"Selected team: {selected_team.get('team_alias', 'N/A')} ({selected_team.get('team_id')})") return selected_team elif key == "quit" or key == "escape": # Clear screen console = Console() console.clear() - click.echo("ℹ️ Team selection skipped.") + click.echo("Team selection skipped.") return None elif key is None: # If we can't get key input, fall back to simple selection @@ -237,7 +235,7 @@ def prompt_team_selection(teams: List[Dict[str, Any]]) -> Optional[Dict[str, Any except KeyboardInterrupt: console = Console() console.clear() - click.echo("\n❌ Team selection cancelled.") + click.echo("\nTeam selection cancelled.") return None except Exception: # If interactive mode fails, fall back to simple selection @@ -265,18 +263,40 @@ def prompt_team_selection_fallback( if 0 <= index < len(teams): selected_team = teams[index] click.echo( - f"\n✅ Selected team: {selected_team.get('team_alias', 'N/A')} ({selected_team.get('team_id')})" + f"\nSelected team: {selected_team.get('team_alias', 'N/A')} ({selected_team.get('team_id')})" ) return selected_team else: - click.echo(f"❌ Invalid selection.
