* feat(cli): add lite autoroute to QA complexity-based auto-routing against a real proxy Lets a customer try litellm's complexity_router against models they already have on their existing, unmodified production proxy, with no config.yaml edits and no new infra. lite autoroute configure discovers accessible models via /model_group/info and walks through tier assignment (plus optional LLM classifier / semantic matching / adaptive selection); every referenced model becomes its own litellm_proxy/<name> deployment forwarding back to the real proxy with the real key, so every actual call, routed completions, classifier calls, embedding calls, still lands on their real proxy. lite autoroute up launches that generated config as an ephemeral local proxy, patches ~/.claude/settings.json to point Claude Code at it, and streams routing decisions live; Ctrl-C/SIGTERM (or lite autoroute down after an unclean exit) restores everything. Also adds lite model-groups list (a thin CLI wrapper over the existing ModelGroupsManagementClient), and generalizes up.py's settings-backup/restore helpers to take explicit paths so this feature can reuse them instead of duplicating the logic. Depends on litellm_lite_up_down (#33231) for that generalization. * feat(cli): allow multiple models per autoroute tier complexity_router already supports a pool of models per tier (randomly picked per request; adaptive mode specifically needs a pool to choose within), but the configure wizard only ever let you assign one. Tiers are now a tuple of model names; the wizard prompt accepts comma-separated indices to pick more than one per tier. * feat(cli): fuzzy model picker and auto-route Claude Code to autorouter Numbered-index selection didn't scale past a handful of models, so switch the tier picker to InquirerPy's fzf-style fuzzy search. Also set ANTHROPIC_DEFAULT_{SONNET,HAIKU,OPUS}_MODEL to "autorouter" in Claude Code's settings, since Router resolves auto-router deployments by literal model name with no wildcard support, so a "*" catch-all model_name would never match real traffic. * feat(cli): allow installing lite CLI from source via LITELLM_CLI_REF Lets testers try an unreleased branch's CLI changes with the same curl-piped installer, instead of waiting for a PyPI release. * fix(ci): modernize type hints to clear ruff strict-rule budget * fix(ci): bump httplib2 and setuptools to patched versions Clears osv-scan findings for PYSEC-2026-3444 and PYSEC-2026-3447. * fix(cli): write autoroute's secret-bearing files with mode 0600 commands.py wrote config.yaml (embeds the real proxy key) and Claude Code's settings.json (embeds the ephemeral proxy's master key) with plain open(), landing at the umask-derived default (commonly 0644) until a later chmod call caught up. That window, and the missed case where settings.json already exists (chmod never ran at all there), left a credential-bearing file readable by another local account. secure_create() fixes the mode via fchmod on the fd before any content is written, covering both the brand-new-file and already-exists cases, and commands.py/wizard.py now route their sensitive writes through it. * docs(cli): warn that a stale Claude Code session can leak to a squatted port lite autoroute up's master key is embedded statically (unlike lite up's apiKeyHelper, resolved per request), so a Claude Code session still running after teardown keeps sending it, along with prompt content, to a now-unbound loopback port that another local account can bind. This is the same one-time-patch tradeoff lite up already accepts, just with a static secret instead of a re-resolved one -- document it in the README's Caveats section and surface it in the teardown message itself. * fix(cli): address greptile review feedback on autoroute PR - terminate the ephemeral proxy child process when its health check fails, instead of leaking an orphaned, unrecoverable process bound to the port - replace bare assert isinstance checks (no-ops under python -O) with click.ClickException in the model-groups list and configure wizard code paths - close launch_proxy's log file handle once the child process has inherited its fd, instead of leaking it - add build_generated_proxy_config to config.py's __all__ * fix(cli): close TOCTOU window in lite up's settings backup write write_backup wrote the backup (which can embed the original apiKeyHelper/settings content) with plain open() + a chmod call after the fact -- the same permissive-until-corrected window already fixed for autoroute's config.yaml and Claude settings writes, and missed entirely when the backup file already exists with broader permissions. Moves secure_create (atomic-enough 0600 via fchmod before any content is written) to up.py, the module both lite up and lite autoroute share, and has autoroute/process.py import it from there instead of keeping its own copy. * fix(cli): refuse autoroute up when a stale backup exists from a crash The pid-record check only catches a still-live duplicate process; a SIGKILL'd `up` leaves no live pid but does leave AUTOROUTE_BACKUP_PATH behind. Without this guard, a fresh `up` overwrote that backup with the currently-patched Claude settings instead of the true originals, so `down`/Ctrl-C would restore the wrong content permanently. up.py's `lite up` already guards the analogous case; mirror it here. * fix(cli): bind the ephemeral autoroute proxy to loopback only proxy_cli.py defaults --host to 0.0.0.0 when not passed explicitly. launch_proxy never passed it, so the ephemeral proxy -- despite every base_url in this module being built from 127.0.0.1 -- was actually reachable from other hosts on the network, including its unauthenticated-until-config-lands routes before the master key is wired in. |

In total litellm runs 1000+ tests
[02/20/2025] Update:
To make it easier to contribute and map what behavior is tested,
we've started mapping the litellm directory in tests/test_litellm
This folder can only run mock tests.
