`_is_model_cost_zero()` reads a group's cost through `Router.get_model_group_info()`, which resolves `model_group_alias`, and then gates that on `_is_cost_explicitly_configured()`, which scanned `Router.model_list` for an exact `model_name` match. Alias names live only in `Router.model_group_alias` and are never `model_name` entries, so the scan found nothing and returned False. That False means "the zero cost was defaulted, not configured" (the sparse auto-registration gate added for #24770), so a model priced explicitly at 0 had budget enforced against it when requested through an alias, while the same deployment under its own name was exempt. Both names route to the same deployment and add nothing to spend. The two lookups in one function disagreeing is the bug, so they now share one resolution: `_is_cost_explicitly_configured()` resolves through `Router.get_model_list()`, the same alias-aware path `get_model_group_info()` takes. That also reaches a deployment which prices itself through its `model_info` block, whose cost-map entry lands under the deployment id. `_group_declares_explicit_cost()` was an alias-aware copy of this function, wired only into `model_has_no_cost_mapping()` and never into the budget path; its body is what `_is_cost_explicitly_configured()` now carries, and both callers share it so the two cannot drift apart again. `_has_ptu_flat_cost()` scanned `model_list` the same way and runs after the gate above, so resolving one without the other would let an aliased PTU group — explicit zero per-token price alongside a flat capacity cost — pass as free. It resolves the same way now. Tests cover the predicate and the request path it feeds: over-budget requests through `_should_skip_budget_checks()` into `common_checks()` for an aliased free model (allowed) and an aliased paid model (refused), the predicate for free, paid, PTU, hidden and dangling aliases, and `model_has_no_cost_mapping()` through an alias so the other caller of the shared check stays covered. Unchanged: priced groups (the predicate returns False before the gate), unmapped groups whose zero cost was defaulted (#24770), hidden aliases and aliases pointing at a nonexistent group (`get_model_group_info()` returns None for both, so the cost is unknown and budget is enforced), and non-aliased PTU groups.

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/unit
This folder can only run mock tests.
