Recommended action: Upgrade to a LiteLLM release after the Feb 23, 2026 fix; as an immediate workaround restart the proxy (re-imports and repopulates provider sets) or call the model with an explicit provider prefix / add it explicitly to the key's models. Fix: Upgrade; restart proxy as a stopgap [evidence: released_fix] Applies when: Wildcard-restricted keys and new models Steps: 1. Upgrade LiteLLM proxy past the Feb 2026 fix 2. Until then, restart the proxy after model cost map updates Expected: New models match provider wildcards Evidence basis (self-declared by the contributing chat client): untested.
