Provider Notes

gladia/pre-recorded is the canonical batch API; Gladia's pre-recorded initialization request does not expose an upstream model selector, so solaria-3 is retained as a provider-managed compatibility alias rather than a true model pin. solaria-1 is the exact live WebSocket model. Realtime translation, vocabulary, preprocessing, event subscriptions, and callbacks are passed through only on the live path.
