Budget is enforced once during auth, against the requested model group. `_is_model_cost_zero` waives every budget check for a zero-cost group, and the router then picks a fallback target afterwards, inside `run_async_fallback`, where nothing re-checks budget. A free model with a paid fallback therefore bills with no budget gate at all. Add `fallback_budget_check`, the budget sibling of the existing `fallback_access_check`: a predicate awaited per fallback target that skips targets the caller cannot pay for. The primary attempt is untouched, so a zero-cost model is never blocked by budget and only the paid fallback is refused. Counter reads pass `max_budget` so `get_current_spend` verifies against authoritative recorded spend, matching the auth-time key and user checks; a counter restored from an older snapshot reads as a hit rather than a clean miss, so without it a stale-low value would keep admitting paid fallbacks. A zero-cost fallback target is always allowed, and a team key does not inherit the key owner's personal budget unless `apply_user_budget_to_team_keys` is set, matching `_PROXY_MaxBudgetLimiter`. Scope is key and user budgets. Team, team-member, end-user, org, global and per-model budgets are not covered yet: those auth-path functions enforce rather than report, so reusing them would fire threshold alerts and take spend reservations for a target that is then skipped. Two limitations of that scope are documented in the module docstring: the check reads the spend counter rather than reserving against it, so concurrent fallbacks can cross a cap together; and a request reaching the router without `metadata["user_api_key_auth"]` is not restricted. Both are shared with `fallback_model_access.py`. Opt-in via `general_settings.enforce_fallback_budget`. Relates to #41344 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

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.
