model not found

Error message

model not found

What it means

Guard in the model update endpoint raised after the DB lookup (ModelRepository.table.find_unique) found no LiteLLM_BrandedDeleteModelTable row for the supplied model_info.id and the in-memory llm_router also has no deployment with that model_id. It means the caller is trying to update a model that does not exist anywhere — a stale or fabricated model id, not a transport or auth problem. Re-check the model id or create the model first via /model/new.
